Best Conversion API Tools 2026

The conversion API category died on April 15, 2026. That was the day Meta shipped a one-click CAPI setup inside Events Manager — no developer, no server, no cost, no maintenance. The floor dropped to zero. And on the same morning you woke up to that news, Google Tag Gateway was already three months old and also free. Any tool charging you to solve the pipe problem in 2026 needs a better answer than "we connect your server to Meta."

The pipe is now a commodity. The water inside it is not.

That distinction is what every comparison article on this topic misses. They rank tools by setup time, platform count, and monthly cost. None of them ask what is actually flowing through the pipe — and whether it is worth sending. If 20% of your traffic is bots, your CAPI is not recovering lost signal. It is automating the delivery of garbage to Meta's algorithm at scale. Project Andromeda, fully deployed October 2025, acts on contaminated conversion signals within hours, not the weeks it used to take for bad data to poison a Lookalike Audience. You are not just wasting budget. You are actively accelerating the deterioration of your targeting.

This article covers 17 tools. It will tell you who each one is for, what it actually costs in 2026, and where it fails. It includes DataCops because I run it and you deserve to know where it fits and where it does not.

What changed in 2026 that makes this decision different

Three things shifted the math between 2025 and now.

Meta's one-click CAPI went live April 15, 2026. Standard web events — page views, add-to-carts, purchases, leads — can now flow server-side from Events Manager in minutes with zero engineering. Meta hosts the infrastructure. For the specific case of a single-store advertiser running only Facebook and Instagram with no bot problem and no multi-platform needs, the category question is answered for free.

Google Tag Gateway launched in January 2026 via one-click deployment on GCP, Cloudflare, or Akamai. Free. Google-native. If all you need is Google Enhanced Conversions and you already run GA4, the infrastructure problem is solved before you open any vendor's pricing page.

ChatGPT Ads Manager went live May 5, 2026. OpenAI's advertising platform is live for US advertisers with a $50K minimum, with CPC bidding and a conversion pixel inside its "bazaar" interface. It matters here for one reason: 70.6% of LLM-driven traffic is misclassified as direct in GA4. Every CAPI tool that feeds only Meta and Google is already blind to a growing conversion channel. The infrastructure decision you make today will either include or exclude that pipeline.

The remaining question, after free takes the basic case, is who needs more than basic. The answer is everyone running meaningful ad spend, advertising on more than one platform, operating in a regulated geography, or doing any volume of lead generation where the quality of the human behind the conversion matters.

Quick answers

Do I still need a paid CAPI tool after Meta's one-click launch?

If you advertise on Meta only, have clean traffic, and do not operate in the EU, the free one-click covers standard web events adequately. The moment you add a second platform (Google, TikTok, LinkedIn), operate in any GDPR-regulated territory, or care about filtering bots before they train your algorithm, free is not enough. One-click handles the pipe. It does nothing about the water.

What is a good Event Match Quality score and how do I improve it?

Meta's EMQ runs on a scale of 0-10. An EMQ of 8.6 is average for a well-configured CAPI integration. Moving from 8.6 to 9.3 delivers approximately 18% lower CPA and 22% ROAS lift. The levers are: matching more customer signals (email, phone, name, address), deduplicating browser and server events cleanly, and eliminating bot events that distort match patterns. Tools that filter bots before the CAPI call tend to report higher sustained EMQ than those that forward everything.

What is the difference between sGTM and CAPI?

Server-side Google Tag Manager is a transport container. Meta CAPI is one of the destinations inside it. They are not the same category. You can run Meta CAPI without sGTM by integrating directly server-to-API. You can run sGTM without sending to Meta. Many setups use both together: sGTM as the routing layer, CAPI as one output. The distinction matters because sGTM still depends on the browser firing an event before the server can relay it — it does not independently observe user behavior. If an ad blocker kills the browser call, sGTM has nothing to forward.

How much conversion data am I actually losing without CAPI?

Pixel-only setups typically miss 20-40% of real conversions due to ad blockers, iOS tracking restrictions, and browser privacy settings. On iOS-heavy audiences running Safari with Link Tracking Protection (which Apple expanded in September 2025 to strip fbclid from Private Browsing, Mail, and Messages), the number is worse. CAPI with proper deduplication closes most of that gap. The 17.8% lower CPA Meta cites in their April 2026 launch data reflects real signal improvement, not just methodology.

What does bot traffic actually do to my CAPI integration?

Every bot event that reaches Meta CAPI gets treated as a conversion signal for audience targeting. Meta's algorithm uses those signals to find more people like that converter. The problem is the converter was a datacenter in Frankfurt. With global invalid traffic at 20.64% (Fraudlogix 2026) and Instagram's IVT at 38%, the typical unfiltered CAPI feed is training audience algorithms on a meaningful share of non-human data. This does not show up as a line item in your ads dashboard. It shows up as gradually worsening ROAS on a Lookalike that used to perform.

What is the realistic cost of a full server-side stack in 2026?

For a mid-traffic Shopify store running Elevar or Littledata plus Stape plus Meta CAPI Gateway, the honest monthly ongoing cost is $475-970, plus $1,000-2,790 in initial setup. Google Cloud Run alone runs $150/month minimum at production scale. This is the context in which a $49/month all-in tool should be evaluated.

Is CAPI enough for EU compliance?

No. CAPI handles the server-to-platform signal pipe. It does not manage consent. In the EU and EEA, Google Ads Consent Mode v2 became mandatory June 15, 2026. You need a TCF 2.2 certified CMP that actually loads on every session to gate identity data correctly before it enters the CAPI pipe. Running CAPI without a functioning consent layer in the EU is not just a data quality problem. It is a legal one.

Does server-side tracking fix Shopify checkout attribution gaps?

Partially. In an April 2026 audit of 27 top DTC Shopify brands, 51.9% were routing checkout to an external Shopify domain. sGTM cannot close this gap because the purchase event never originates in merchant JavaScript. Shop Pay, Apple Pay, PayPal, and iframe checkouts fire outside your tracking container entirely. Shopify-native apps like Elevar and Littledata handle this at the platform level, which is why they command a premium despite the existence of cheaper generic server-side tools.

How to pick before you read 17 reviews

The decision tree is shorter than most people make it.

If you advertise on Meta only, do not operate in the EU, and have fewer than 5,000 sessions a month: use Meta's one-click CAPI for free and spend the money you saved on actual ads.

If you run Shopify at scale (100K+ monthly sessions, $500K+ GMV) and Shopify-native order fidelity is the primary concern: Elevar at $200-950/month is purpose-built. You will overpay relative to alternatives but you will get order-level accuracy that generic server-side tools miss.

If you have in-house GTM engineers who want full container control and the ability to customize every tag: Stape at $17/month hosting is the infrastructure play. Budget separately for the engineering time; it is real.

If you are an EU-focused brand or agency that needs documented GDPR compliance, SOC 2 certification, and legal paper trail with a large vendor: Tracklution (€31/month) or JENTIS (€199/month) are the serious European options with the compliance posture to match.

If you need multi-platform CAPI (Meta plus Google plus TikTok plus LinkedIn), first-party CMP that actually loads on every session, and bot filtering before any event fires, and you want all of that for $49/month: that is what DataCops was built to do.

The tools

DataCops

DataCops is a first-party analytics platform, TCF 2.2 CMP, and multi-platform CAPI in one architecture. Setup is one script tag plus one CNAME record, typically live in 5-30 minutes with no developer required. It works on Shopify, WooCommerce, Webflow, and custom builds.

The product solves three problems simultaneously that every other tool solves separately or ignores entirely.

The first is consent. DataCops' CMP loads from your subdomain (datacops.yourdomain.com), not from a third-party CDN. Competitor CMPs — OneTrust, Cookiebot, Usercentrics — load from CDNs that uBlock Origin and Brave block 30-40% of the time. When the banner does not load, consent is never recorded, and in the EU, tracking never fires. You lose those sessions entirely without ever knowing it happened. A first-party CMP that loads on every session is the prerequisite for accurate EU data, and it is bundled here rather than a separate $11-10,000/month line item.

The second is identity. DataCops uses cookieless persistent first-party identity resolution instead of cookies. No ITP decay, no 7-day browser deletion, no expiry. For EU traffic, identity resolution gates behind TCF 2.2 consent. For US, UK, and APAC traffic where consent was never legally required, it activates by default. Returning customers are recognized as returning customers across sessions without relying on a cookie that Safari will quietly delete.

The third is the CAPI pipe itself. DataCops runs bot filtering before any event fires, not after. The IP database covers 361,873,948,495 IPs: 146.4 billion datacenter and cloud IPs, 202 billion residential and mobile carrier IPs, 11.9 billion VPN endpoints, 620 million proxy and anonymizer IPs, and 160,000 fraud email domains. Up to 98% of automated traffic is filtered. Puppeteer, Selenium, and Playwright are detected. The CAPI output on the other end reflects real human conversions. That matters for the same reason a clean dataset matters before you run a model: garbage in, algorithm poisoned, ROAS degrades.

Multi-platform output at Business tier ($49/month): Meta CAPI, Google Ads Enhanced Conversions, TikTok Events API, LinkedIn Insight CAPI, and HubSpot. No Pinterest. No Snapchat.

The proof case: PillarlabAI ran 4,560 signups over 4 weeks. DataCops flagged 3,830 as fraudulent. 730 were real humans. 650 accounts came from one laptop. They would have fed all 4,560 into a Meta audience and a HubSpot CRM without that filter.

What does not work: DataCops is newer than Stape, Elevar, and Datahash. SOC 2 Type II certification is in progress, not complete. The integration catalog is narrower than enterprise CDPs — no Segment pipeline, no Snowflake connector, no Salesforce native hook at launch. If you are an enterprise running a multi-warehouse data infrastructure or need a vendor with a decade of enterprise contracts behind them, the maturity gap is real and you should evaluate accordingly.

Right for: Multi-platform advertisers below the enterprise threshold who need clean CAPI data, a first-party CMP that actually loads, and do not want to assemble five separate tools to get there.

Value: 9/10. No other single tool at this price delivers bot-filtered CAPI across four platforms plus a first-party CMP plus cookieless identity resolution.

Pricing: Free ($0, 2,000 sessions, no CAPI). Growth ($7.99/month, 5,000 sessions, no CAPI). Business ($49/month, 50,000 sessions, CAPI starts here). Organization ($299/month, 300,000 sessions). Enterprise (custom).

Meta Conversions API (one-click, native)

Meta's own CAPI, now accessible via one-click setup in Events Manager since April 15, 2026, with no cost, no server, and no developer. Meta hosts the infrastructure. For standard web events (page view, add-to-cart, purchase, lead), this now works without any third-party tool. The EMQ improvement is real: advertisers with CAPI for web events saw 17.8% lower cost per result compared to pixel-only setups per Meta's April 2026 launch data.

What does not work: Meta-only, full stop. No Google Enhanced Conversions, no TikTok Events API, no LinkedIn. No bot filtering — every traffic source flows through, bots included. No consent management. Custom events require additional configuration. If your audience is EU-heavy, the consent gap this creates is a compliance problem, not just a data quality one. The one-click CMP is Meta's, which means Meta decides what data gets shared back with Meta, without an intermediary.

Right for: Single-platform Meta advertisers with clean traffic, no EU exposure, and basic event sets. The free baseline before you evaluate whether you need more.

Value: 10/10 for what it costs. Exactly right for its use case.

Pricing: Free. AWS-hosted variant (CAPI Gateway) runs $5-30/month in infrastructure.

---

Google Tag Gateway

Google's answer to Meta's one-click, shipped January 2026. One-click deployment on Google Cloud Platform, Cloudflare, or Akamai. Routes Google Ads Enhanced Conversions through a first-party domain, improving match rates on cookieless and iOS-affected traffic. Free. No ongoing maintenance.

What does not work: Google Ads only. No Meta, no TikTok, no LinkedIn. No bot filtering, no CMP, no analytics layer. Like Meta's one-click, it solves the pipe for one platform and nothing else. If you need Google Enhanced Conversions and nothing else, this is the correct decision.

Right for: Google Ads-only advertisers or as one component of a multi-platform stack (not the whole stack).

Value: 10/10 for its scope. The free option for the Google pipe.

Pricing: Free. GCP compute costs apply at scale, typically under $10/month for most sites.

---

Stape

Stape is the most popular server-side GTM hosting platform, and it earned that position by being genuinely cheap and flexible. At $17/month for the Pro plan, you get managed sGTM hosting with 80+ pre-built templates covering Meta CAPI, Google, TikTok, and more. The template library is legitimately extensive. Agencies managing multiple clients find it economical at scale, and the tagging infrastructure is the same sGTM that enterprise teams run on custom Cloud Run deployments, just hosted and managed.

What does not work: Stape is infrastructure. It does not come with analytics, bot filtering, or a CMP. You assemble those separately, which means separate cost and separate maintenance. Setting up and debugging server containers requires real GTM fluency. A non-technical marketer cannot do this alone. The 80% of sGTM setups detected by Bounteous research as identifiable-despite-server-side is a real concern: a custom CNAME mitigates it but requires additional configuration. Server-side still depends on the browser firing the initial event. If an ad blocker kills the page view tag before it can relay, Stape relays nothing.

Right for: In-house GTM engineers or agencies with dedicated tagging resource who want full container control and cheapest possible infrastructure.

Value: 7/10. Genuinely cheap for what it does, but the missing layers are not free.

Pricing: $17/month Pro, $83/month Business. Add $50-300/month Cloud Run if you want the self-hosted variant. Engineering time is an additional unlisted cost.

---

Elevar

Elevar is the Shopify-native tracking platform built specifically for ecommerce operators who care about order-level attribution fidelity. Six thousand five hundred brands use it. The product handles the Shopify data layer, server-side tracking, and CAPI output for Meta and Google in a way that accounts for Shopify-specific edge cases: Shop Pay, headless builds, subscription flows, and external checkout domains. When a purchase fires outside merchant JavaScript, Elevar catches it where a generic sGTM setup cannot.

What does not work: Shopify only. Period. If you run WooCommerce, Webflow, or a custom stack, Elevar does not apply. The pricing model escalates sharply with order volume: $200/month for 1,000 orders, $950/month for 50,000 orders. No bot filtering — Elevar forwards everything it observes. No built-in CMP; you pay separately for consent management. The gap between what Elevar costs and what DataCops or Tracklution costs at equivalent session volumes is significant enough to calculate explicitly before committing.

Right for: Shopify-only brands doing $500K+ GMV per month who need order-level accuracy and have budget for a premium Shopify-native solution.

Value: 6/10 at the $950/month tier. Strong product, but the Shopify-only constraint and bot-blind CAPI output are real limitations at that price.

Pricing: $200/month Essentials (1,000 orders), $950/month Business (50,000 orders). Custom above that.

---

Tracklution

Tracklution is a fully managed server-side tracking service with no-code setup, ~30-minute implementation, and transparent SaaS pricing. It does not require GTM expertise, does not require a developer, and covers Meta CAPI, Google Enhanced Conversions, and TikTok Events API. The EU compliance posture is serious: the platform is built in Finland, data stays on Stockholm servers, and the documentation around GDPR handling is clear. Agencies managing multiple client accounts find the multi-domain setup workable.

What does not work: No bot filtering. Tracklution sends what it observes, including all automated traffic. No built-in CMP — you buy that separately. LinkedIn Insight CAPI is not included. The tool does not have the depth of a Shopify-native solution like Elevar for order-level Shopify edge cases. At €31/month it is excellent value, but the data quality coming out the other end is only as good as the data going in, and there is no filter at the door.

Right for: EU-focused agencies and marketers who want clean managed server-side tracking without the GTM prerequisite, particularly on non-Shopify stacks.

Value: 8/10. Best value managed sGTM alternative in the European market.

Pricing: €31/month Starter. Custom Enterprise with SOC 2 Type II and ISO 27001 certification.

---

Littledata

Littledata is the surgical fix for Shopify stores whose primary complaint is "my GA4 data is inaccurate." It handles server-side event collection for GA4, Segment, and Meta CAPI, with particularly strong handling of subscription revenue tracking — a gap that most CAPI tools either ignore or handle poorly. The case studies show consistent checkout capture improvements; Future Kind reported 205% more checkout events captured versus pixel-only. The Segment integration is the cleanest in this category for stores that route data through a CDP before forwarding to ad platforms.

What does not work: No bot filtering. No CMP. No LinkedIn or TikTok CAPI. The product is genuinely narrow — it excels at GA4 accuracy and subscription commerce tracking and does not pretend to be a multi-platform CAPI orchestration layer. Pricing by order volume makes costs unpredictable at scale for high-volume DTC brands.

Right for: Shopify subscription brands where GA4 accuracy and Segment pipeline fidelity are the primary pain points.

Value: 7/10. Does its specific job extremely well. Overpriced if GA4 accuracy is not your primary concern.

Pricing: $199/month Standard, $0.35/order variant available.

---

TrackBee

TrackBee is a European server-side tracking tool aimed at ecommerce brands, particularly on Shopify and WooCommerce. It covers Meta CAPI and Google Enhanced Conversions, with a clean onboarding flow that requires no GTM expertise. The product positions itself on data accuracy with a visible Tracking Score metric in the dashboard, giving operators a real-time read on signal completeness. EU compliance documentation is solid.

What does not work: No bot filtering. No built-in CMP. TikTok and LinkedIn are not covered. The pricing is higher than Tracklution without a clear feature advantage over it. Limited case study data compared to Elevar or Littledata.

Right for: European ecommerce brands on Shopify or WooCommerce who want a no-code managed option with transparent EU data handling.

Value: 6/10. Solid but not differentiated enough to command a premium over Tracklution at similar traffic volumes.

Pricing: €79/month.

---

SignalBridge

SignalBridge is worth covering because it is the only other tool in this category that includes bot filtering alongside CAPI, which makes it a direct competitor in the layer that most tools ignore. At $29/month, it covers Meta CAPI, Google Enhanced Conversions, and TikTok Events API, with funnel analytics and ad spend sync included. Setup is 5-15 minutes with no developer required. The bot filtering is present but uses a smaller IP database than DataCops; the published comparison is 361 billion IPs (DataCops) versus SignalBridge's undisclosed database size.

What does not work: No built-in CMP. No LinkedIn Insight CAPI. No cookieless persistent identity architecture — SignalBridge relies on first-party cookies, which means ITP degrades identity over a 7-day window for Safari users. The analytics layer is functional but not a replacement for dedicated first-party analytics if that is a priority.

Right for: Small-to-mid advertisers on three platforms (Meta, Google, TikTok) who want bot filtering at the lowest price point without building a CMP separately.

Value: 8/10. Strong value relative to price. The bot filtering and tri-platform coverage at $29/month is legitimately competitive.

Pricing: $29/month.

---

Aimerce

Aimerce is a Shopify-native CAPI tool that built its differentiation on EMQ optimization. The Durable ID extends visitor tracking from the standard 7-day ITP window to a full year using first-party cookies, and the Meta CAPI Enhancer pushes EMQ scores above 9.4 by fixing data mismatches and enforcing Meta's data quality rules at the source. For brands where 60% of conversions happen outside the 7-day default window (a real number from their published jewelry brand case study), this identity persistence is meaningful revenue recovery.

What does not work: Shopify only. The identity persistence relies on first-party cookies — which means Safari's ITP can still clear them after 7 days for some users, and the Durable ID carries that dependency. No bot filtering. No CMP. At $299/month for 1,000 orders, the pricing is aggressive for a tool that is purely a CAPI enhancer with no analytics layer and no multi-platform output for TikTok or LinkedIn.

Right for: Shopify brands with high-EMQ sensitivity, long consideration cycles (luxury, jewelry, high-ticket), or subscription models where the 7-day attribution window misses actual purchase behavior.

Value: 6/10. Strong for its specific use case, expensive for what it excludes.

Pricing: $299/month Essential (1,000 orders), $499/month Growth (10,000 orders).

---

Cometly

Cometly is an attribution platform that includes CAPI functionality. The positioning is "understand which ads drive revenue" rather than "fix your tracking infrastructure." It wraps multi-touch attribution, creative performance analytics, and a unified dashboard around a server-side tracking layer that covers Meta, Google, TikTok, and other platforms. For a buyer who wants attribution intelligence alongside the CAPI plumbing, the combination is appealing.

What does not work: No bot filtering. No built-in CMP. The attribution layer adds cost relative to pure CAPI tools, which means you are paying for attribution features even if attribution is not your primary problem. The pricing is sales-led, which typically means the number is higher than you expect before the conversation. Users comparing it to DataCops or Tracklution on pure CAPI value will find the price-to-pipe ratio unfavorable.

Right for: Mid-market advertisers who genuinely need multi-touch attribution reporting alongside their CAPI infrastructure and are willing to pay for both in one platform.

Value: 6/10 for CAPI use case specifically. Higher if the attribution dashboard is a primary need.

Pricing: $199-499/month (sales-led; final pricing varies).

---

Triple Whale

Triple Whale is an ecommerce analytics platform with CAPI features. It is not primarily a CAPI tool. The product's core value is profit-and-loss analytics, creative performance reporting, and LTV modeling for Shopify brands. The first-party pixel and CAPI output are part of the stack, not the stack itself. If your primary need is a live profit dashboard that integrates ad spend with COGS and shipping, Triple Whale delivers that in a way that pure CAPI tools do not attempt.

What does not work: No bot filtering. The CAPI output is only as clean as the traffic it observes. The pricing starts at $179/month annual and scales by GMV, reaching significant numbers at high-volume stores. It is substantially more expensive than pure CAPI tools for buyers who primarily care about server-side signal quality. The product makes no pretense of being a tracking infrastructure tool; it is a business intelligence layer that happens to include tracking.

Right for: Shopify brands doing $1M+ GMV who want profit intelligence, LTV modeling, and creative analytics alongside a CAPI integration, and who are willing to pay for all of it together.

Value: 7/10 as an analytics platform. 4/10 evaluated purely on CAPI signal quality per dollar.

Pricing: $179/month annual, $259/month Advanced. GMV-based pricing above $5M.

---

Northbeam

Northbeam is a media mix modeling and attribution platform for high-spend advertisers. Entry price $1,500/month, scaling to $5,000-10,000/month for large brands. The product uses machine learning attribution that operates across channels including paid social, search, and organic — not just CAPI channels. The incrementality testing is genuinely sophisticated and produces insights that simpler tools cannot replicate. The customer base is serious media buyers spending $500K+/month on advertising.

What does not work: Not a CAPI tool in the infrastructure sense. If you are looking for server-side event delivery to ad platforms, Northbeam is the wrong product category. No bot filtering. The pricing is prohibitive for anyone below the enterprise threshold. The contract structure is typically annual, which is a significant commitment at $18,000/year minimum.

Right for: Performance marketing teams at large brands who need channel-level media mix modeling and have the ad spend to justify the insight layer.

Value: 8/10 for its intended buyer. 2/10 for anyone evaluating it as a CAPI tool.

Pricing: $1,500/month entry. $5,000-10,000/month at scale.

---

Datahash

Datahash is an enterprise-grade CAPI and data connectivity platform. It handles clean room integrations, first-party data hashing and matching, and multi-platform CAPI delivery with documented compliance posture for large brands. The product covers Meta, Google, TikTok, Snapchat, Pinterest, LinkedIn, and others — the broadest platform coverage in this list. Setup is always implementation-assisted, not self-serve. The customer base is typically enterprise retail, finance, and media.

What does not work: Custom quote pricing, typically $500-2,000/month at minimum. No self-serve onboarding. Not appropriate for any brand below enterprise size. No bot filtering in the published feature set. The product requires procurement-level engagement; it is not a tool you trial on a credit card.

Right for: Enterprise brands that need documented compliance, clean room CAPI connectivity, and support for platforms beyond Meta and Google including Snapchat and Pinterest.

Value: 8/10 for enterprise buyers who need the platform coverage and compliance paper trail.

Pricing: Custom. Most deployments $500-2,000/month.

---

JENTIS

JENTIS is an Austrian-built server-side tracking platform that takes a fundamentally different compliance approach from the rest of the category. The Synthetic Users technology uses AI to model what opted-out users would have done — recovering conversion intelligence from consent-rejected sessions without using their actual data. The Tracking Score dashboard shows a reported +61.5% more data captured versus client-side baseline. Documentation for GDPR compliance is the most thorough in this list, built for the German and Austrian regulatory environment where enforcement has actual teeth (the CNIL fined Google €325M in September 2025; that number shapes what "compliance" means to European brands).

What does not work: €199/month entry price is the second-highest in this list for pure tracking tools. The product is genuinely complex and implementation requires significant onboarding effort. Outside of Europe and companies with active GDPR exposure, the compliance investment is over-specified. No bot filtering in the standard product.

Right for: EU enterprises with GDPR exposure where the legal risk of non-compliance exceeds the cost of the most thorough compliance tool available.

Value: 9/10 for EU enterprise compliance use case. 5/10 for everyone else at that price.

Pricing: €199/month and €549/month. Enterprise custom.

---

Addingwell (now Didomi)

Addingwell was acquired by Didomi in April 2025 for $83M — the clearest signal the market sent about where this is heading. The combined entity now offers CMP plus server-side GTM in one vendor, which is the same architectural thesis as DataCops but aimed at the enterprise/agency market rather than SMB. The acquisition means Addingwell's sGTM hosting is now backed by Didomi's consent infrastructure, which is genuinely useful for EU-heavy agencies that previously bought these separately.

What does not work: The integration of two acquired products is never seamless at launch. Pricing has increased post-acquisition and is now enterprise-first. The free tier covers 100K requests/month; above that it scales in EUR-based usage pricing that can surprise at high volume. No bot filtering. The product is an EU compliance plus sGTM play, not a bot-filtered CAPI play.

Right for: EU agencies and large brands that already use Didomi for consent and want to consolidate server-side tracking under the same vendor relationship.

Value: 7/10 post-acquisition. Good combined product at a price that reflects the enterprise positioning.

Pricing: Free (100K requests/month). EUR-based usage pricing above that. Enterprise custom.

---

Converge

Converge is a YC S23 company positioning as "Segment for ecommerce" — a first-party CDP that handles event collection, identity resolution, and CAPI delivery to Meta, Google, TikTok, Klaviyo, and others in a unified pipeline. The developer experience is genuinely good: the tracking pixel is less than 1KB, the SDK documentation is clean, and multi-destination routing is managed without GTM. For ecommerce brands that think about data as a pipeline problem (collect once, route everywhere), Converge addresses the architecture more elegantly than assembling separate tools.

What does not work: $3,600/year ($300/month) for the standard plan, with custom pricing above. No bot filtering. No CMP. The product requires more technical involvement than Tracklution or DataCops — it is the right call for a team that wants control over the data model, not for a marketer who wants it running in 30 minutes. Platform coverage is strong but the maturity of the company (YC 2023) means less battle-testing on edge cases than Elevar or Tracklution.

Right for: Technical ecommerce teams who want a Segment-style event infrastructure with CAPI output and are comfortable paying CDP-level pricing for the architectural flexibility.

Value: 7/10. Technically strong. Expensive relative to simpler managed tools if pipeline architecture is not a priority.

Pricing: $3,600/year ($300/month). Custom above.

---

Feature comparison

DataCops is the only tool with all four: bot filtering, first-party CMP, four-platform CAPI, and no developer requirement. At $49/month, it is the only tool in this list that bundles all of these at SMB pricing. Every other tool with multi-platform CAPI either lacks a CMP, lacks bot filtering, or charges enterprise pricing.

---

The question that matters more than this list

Every tool in this article solves the pipe problem to some degree. Meta and Google solved the most common version of it for free in the first four months of 2026. The CAPI category is not about whether you have a pipe. Most of you already do or can have one for nothing.

The question is what is actually flowing through it.

The conversions you sent Meta last month — how many of them can you prove were real humans from real sessions who made a genuine purchase decision? If you cannot answer that with a number, your Lookalike Audiences are trained on a dataset you have never audited, your CPA benchmarks are measuring a population that does not exist, and every campaign you optimize against that baseline is learning from noise. The pipe is clean. The water is not.

Before you pick a tool from this list, run that audit. Your CAPI dashboard will not tell you. Your Meta Ads Manager will not tell you. The number lives in your traffic logs, and most people have never looked.
