# CPV Lab Pro vs Cometly (2026) · OfferROAS > Source: https://offerroas.com/compare/cpvlab-pro-vs-cometly ## CPV Lab Pro vs Cometly By [Marcus Flynn](/authors/marcus-flynn), tracking and attribution editor. Updated 24 September 2026. You are down to two tools that both get called ad tracking and solve opposite problems. One routes your paid media through a server you own and rotates the offers and landers you test. The other attributes the traffic that lands on a site you already run, and ties it to the revenue in your Stripe and CRM. The right pick is decided by which of those two jobs is yours. **Disclosure:**We may earn a commission when you buy through links on this page. It never affects our rankings. Pick CPV Lab Pro if you buy paid traffic at volume and route clicks through your own server to offers and landers you test and rotate, want unlimited events on a flat or one-time price, and can host it yourself; pick Cometly if you run a B2B SaaS business and need ad spend tied to Stripe revenue and CRM pipeline, right through to closed-won ARR. Quick answer **CPV Lab Pro** is our top pick for most people. For a buyer moving real paid-media volume, CPV Lab Pro is the pick. It is a genuine self-hosted route-through tracker: you route traffic through it, rotate offers, split-test landers and forward conversions to Meta, TikTok, Google and Microsoft, all on unlimited events with no overage, on a server and data you own. You pay for that with the Linux box you have to run and keep patched, which is the honest catch. If you already run a VPS and would rather own the stack than rent it, it is one of the better-value trackers in the lane, and a one-time licence removes the monthly bill entirely. * **CPV Lab Pro.** Best for Paid-traffic affiliates and media buyers who want a tracker they own and host themselves. From $57/mo. * **Cometly.** Best for B2B SaaS teams tying ad spend to Stripe revenue and CRM pipeline. ### Side by side __Feature comparison across 2 tools__ | Tool | Core job | Delivery | CAPI reach | Setup | From | | ----------- | ---------------------------------- | ----------------------------- | ------------------------ | ------------------------ | ---------- | | CPV Lab Pro | Self-hosted route-through tracking | Self-hosted, unlimited events | Meta, TikTok, Google, MS | Own server; 14-day trial | $57/mo | | Cometly | B2B SaaS attribution | Cloud, quote-only | Meta, Google, LinkedIn + | Demo, no trial | Not listed | ### CPV Lab Pro: pros and cons ##### What works * You own it. CPV Lab is self-hosted, so your click data, redirects and tracking domains live on hardware you control, not inside a cloud plan. Every tier is unlimited events and unlimited campaigns, so a winning campaign that suddenly does volume never trips an overage fee or a plan-limit wall. * It is a real route-through tracker, not a light attribution layer. Direct-link and landing-page campaigns, multiple-path and listicle funnels, offer rotation and landing-page split testing are built in, with S2S postbacks into 300-plus preconfigured traffic sources and affiliate networks, and cookieless tracking that keeps firing on iOS and Safari. This is the media-buyer job the cloud trackers charge more for. * Conversion API forwarding starts on the Pro plan: server-side conversions back to Meta, TikTok, Google Ads and Microsoft, with enriched signals (email, phone, custom parameters) on Expert. Cleaner signal to the ad platforms means their algorithms optimize against real conversions instead of a browser pixel that iOS keeps breaking. * Support is the single most repeated piece of praise. G2 sits at 4.9 out of 5 across 11 reviews and Capterra at 4.9 across 17, with a 4.9 for customer service, and reviewers name specific agents who help with install and campaign setup. It undercuts the cloud incumbents on price, and a one-time lifetime licence removes the monthly fee entirely if you would rather buy than rent. ##### What to watch * It is self-hosted, so you own the server as well as the tracker. A Linux VPS, PHP, MySQL, the ionCube Loader, SSL, tracking domains and cron jobs are yours to stand up and keep patched. That weighs most on a non-technical buyer or a solo operator with no server experience; a media buyer who already runs a VPS will find the install, which the vendor's onboarding call walks through, a small tax for owning the data. * The work does not end at install. Before your first campaign tracks you still configure traffic sources, postbacks or CAPI, and custom domains, and one user reported the Google Ads API conversion import not working for them. Plan an afternoon and lean on support rather than expecting it to track the moment it is live. * Independent proof is thin in absolute numbers. The 4.9 scores on G2 and Capterra are real but rest on 11 and 17 reviews, and a lot of the praise on the vendor's own site is testimonials it collected. Weigh it against your own 14-day trial and the 30-day money-back window, not the star count. * The lifetime licence is capped to version 13\. Pay once and you keep the version you bought and its updates within v13, but a future major version is a separate purchase and support on that one-time deal ends four major versions on. If you want the newest features indefinitely, the monthly or yearly plan, not the pay-once price, is the honest option. ### Cometly: pros and cons ##### What works * Server-side Conversion API is the genuine strength. Cometly sends deduplicated conversions back to Meta, Google, LinkedIn and TikTok, and reports Meta event match quality up to 9.3 out of 10 where a manual setup sits at 4 to 5. * Revenue attribution built around Stripe and the CRM, not just clicks. The native Stripe sync ties trials, new customers, recurring revenue and LTV to the originating ad, right through to closed-won ARR. That is the report a SaaS finance team will actually defend. * Modern data plumbing under it. A cookieless Comet Pixel with cross-device identity, 70-plus native integrations, an Agent you query in plain English, and on Enterprise a warehouse sync to Snowflake or BigQuery plus an MCP server. The vendor puts setup at hours rather than weeks. * Established and reviewed, not a new app. Comet LLC has tracked paid spend for years, with named case studies (ClickFunnels reports a 31% ad-return lift, Trainual a 40% improvement in 90 days). ##### What to watch * It is not a route-through campaign tracker. Cometly attributes traffic to your own site and funnel; it does not rotate offers, split traffic across landers by rule, or distribute clicks the way Voluum, RedTrack or Binom do. A media buyer running many offers through a redirect needs that, and Cometly does not have it. * It has left the DTC and ecommerce market it once served. Cometly's own site now names Triple Whale as the ecommerce tool. Shopify still integrates, but reviewers report weaker matching on cash-on-delivery and email-less orders, so an ecom brand should demand proof on its own orders. * No public price and no free trial. Every plan is usage-based on monthly pageviews and quoted on a sales call, and Cometly says it does not run a trial because attribution needs setup first. Buyers who want to test against their own numbers before paying get neither. * Support and journey timing draw the recurring complaints. The long-running r/FacebookAds thread reports support replies measured in business days and trouble seeing the full pre-purchase journey. The sample is small, but consistent enough to test response times during onboarding. ### The real differences #### What each one actually is CPV Lab Pro is a self-hosted performance-marketing tracker. You install it on your own Linux server, route your campaign links through it, and it stamps every click, records the conversion your network or pixel posts back, rotates offers, split-tests landing pages, and reports profit by campaign, source, offer and creative. It has been in affiliates' hands for years, and what it sells is a route-through tracker you own outright: the click data, the redirects and the tracking domains all live on hardware you control. Cometly is a marketing attribution platform. You install its Comet Pixel with one line, and it captures every visitor cookielessly and across devices, records the conversion server-side so ad blockers and iOS restrictions do not drop it, and models the full multi-touch journey back to the campaign, ad and creative that drove it. Its headline job in 2026 is revenue attribution for B2B SaaS: a native Stripe integration ties trials, new customers, recurring revenue and LTV to the originating ad, and HubSpot or Salesforce lifecycle stages map onto the same touchpoints, right through to closed-won ARR. #### Do they even compete? Barely They share the label ad tracking and little else. CPV Lab Pro routes and rotates traffic through a redirect you own, and reads conversions back through postbacks into 300-plus preconfigured traffic sources and networks. Cometly does not route traffic at all. It attributes the traffic that lands on a site and funnel you already run, and its centre of gravity is a revenue report a SaaS finance team can defend, not a campaign a media buyer rotates. If you are choosing between these two, you are usually not really choosing at all: one of them is built for the business you run and the other is built for a business you do not. Settle which job is yours first, and the tool follows. #### Where they overlap: sending conversions back to the ad platforms The one place they meet is server-side conversion feedback, and here Cometly is the stronger of the two on the merits. Its Conversion API sends deduplicated conversions to Meta, Google, LinkedIn and TikTok, and it reports Meta event match quality up to 9.3 out of 10 where a manual setup sits at 4 to 5\. CPV Lab Pro forwards conversions server-side to Meta, TikTok, Google Ads and Microsoft too, starting on its Pro plan, with enriched signals like email and phone on Expert. If the only thing you cared about were the quality of the signal going back to Meta, Cometly would edge it. But for the reader on this site, that signal is one feature of a tracker, not the tracker: CPV Lab Pro pairs it with the routing, rotation and split-testing that Cometly does not do at all. #### How each one bills you CPV Lab Pro publishes its price and lets you self-serve: three unlimited-event tiers, or a one-time lifetime licence, plus the server you host it on. Cometly publishes no price at all. Every plan is usage-based on monthly pageviews and quoted on a sales call, and Cometly says it does not run a trial because attribution needs setup first. So one is a visible, testable cost you can stand up in an afternoon, and the other is an opaque quote you get after a demo. The honest comparison is not which line is lower. It is which one matches the business you are running, because the cheaper number for the wrong job is still money spent on the wrong tool. #### Who should pick which Pick CPV Lab Pro if you buy paid media at volume, route clicks through offers and landers you test and rotate, and want to own the tracker and its data on a server you run, at a flat unlimited-event price or a one-time licence. Pick Cometly if you run a B2B SaaS business and need ad spend tied to Stripe revenue and CRM pipeline through to closed-won ARR, and you can host that on a cloud platform quoted on a call. Neither is a substitute for the other: CPV Lab Pro will not tie your ads to Stripe MRR, and Cometly will not route or rotate a media campaign. Know which job you are buying, and the choice makes itself. ### What each one costs **CPV Lab Pro.** Three tiers, each unlimited on events with no overage: Starter at $57 a month, Pro at $97 (where Conversion API forwarding to Meta, TikTok, Google and Microsoft begins), and Expert at $187 (adding enriched CAPI signals). Billed yearly the same tiers fall to $48, $81 and $156 a month. Every plan also sells as a one-time lifetime licence instead, a single payment of $1,157 to $3,757, capped to version 13\. A 14-day trial runs with no card, with a 30-day money-back window. On top of any of these you pay for the Linux server it runs on, so budget for a VPS, tracking domains and the upkeep that comes with owning the box. **Cometly.** No public price. Two plans, Core and Enterprise, are priced on monthly pageviews and quoted after a demo, with annual billing about 20% cheaper than monthly. There is no free trial, because Cometly says attribution needs setup before it means anything. So you cannot test it against your own numbers before you pay, and you cannot even see a figure before a call. The two prices are not comparable line to line: CPV Lab Pro is a visible, self-serve cost you own, and Cometly is an opaque usage quote for a different job. Prices read from each vendor's own pricing page, current as of 23 September 2026. Our pick ### CPV Lab Pro For a buyer moving real paid-media volume, CPV Lab Pro is the pick. It is a genuine self-hosted route-through tracker: you route traffic through it, rotate offers, split-test landers and forward conversions to Meta, TikTok, Google and Microsoft, all on unlimited events with no overage, on a server and data you own.

If you already run a VPS and would rather own the stack than rent it, it is one of the better-value trackers in the lane, and a one-time licence removes the monthly bill entirely. ### Frequently asked questions CPV Lab Pro or Cometly: which should I pick? Pick CPV Lab Pro if you buy paid traffic at volume, route clicks through your own server to offers and landers you test and rotate, want offer rotation, split-testing and unlimited events on a flat or one-time price, and can host it yourself. Pick Cometly if you run a B2B SaaS business and need ad spend tied to Stripe revenue and CRM pipeline, right through to closed-won ARR. They do different jobs, so the answer is usually clear once you know which one you are. Do CPV Lab Pro and Cometly even compete? Barely. They share the label ad tracking and little else. CPV Lab Pro is a self-hosted route-through tracker that rotates offers and landers through a redirect you own and reads conversions back through network postbacks. Cometly is a cloud attribution platform that does not route traffic at all; it ties ad spend to Stripe revenue and CRM pipeline for a B2B SaaS. The one place they overlap is sending server-side conversions back to the ad platforms, and even there Cometly's Conversion API is the stronger of the two. Is CPV Lab Pro or Cometly cheaper? There is no clean headline comparison. CPV Lab Pro publishes its price and starts at $57 a month with unlimited events and no overage, plus the Linux server you host it on, and it also sells each plan as a one-time lifetime licence for $1,157 to $3,757\. Cometly publishes no price at all: two plans priced on monthly pageviews and quoted after a demo, with annual billing about 20% cheaper than monthly and no free trial. So CPV Lab Pro is the visible, self-serve cost and Cometly is an opaque usage quote, and the honest comparison is which one matches your business, not which line is lower. Which one sends better conversion data back to Meta and Google? Cometly, on the merits. Its server-side Conversion API is its strongest feature, sending deduplicated conversions to Meta, Google, LinkedIn and TikTok with Meta event match quality reported up to 9.3 out of 10\. CPV Lab Pro forwards conversions server-side to Meta, TikTok, Google and Microsoft too, starting on its Pro plan, with enriched signals on Expert, so the gap is smaller than it looks. But CPV Lab Pro pairs that feed with routing, rotation and split-testing that Cometly does not do, so a media buyer is choosing a whole tracker, not just a conversion pipe. ### Sources #### Other sources 6 discussions and reviews read for this page.
