Cometly vs PeerClick

Two tools that barely overlap

If you are genuinely down to these two, start by noticing that they are not two versions of one product. They share a single feature, server-side conversion tracking, and almost nothing else. Cometly is a marketing attribution platform built for B2B SaaS: it ties an ad to Stripe revenue and CRM pipeline, all the way to closed-won ARR. PeerClick is an in-path click tracker built for affiliate and iGaming media buyers: you route paid traffic through it and it moves budget toward the offers that convert, minute by minute. So the real question is not which is better in the abstract. It is which business you run, because that decides the answer cleanly.

What Cometly is built to do

Cometly is a marketing attribution platform. You install its Comet Pixel with one line, it captures visitors cookielessly and across devices, records the conversion server-side so ad blockers and iOS restrictions do not drop it, and models the multi-touch journey back to the ad and creative that drove it. In 2026 its headline job is revenue attribution for software companies: a native Stripe sync ties trials, new customers, recurring revenue and lifetime value to the originating ad, and HubSpot or Salesforce lifecycle stages map onto the same touchpoints, right through to closed-won ARR. Its genuine strength is the server-side Conversion API: it pushes deduplicated conversions back to Meta, Google, LinkedIn and TikTok and reports Meta event match quality well above a hand-rolled setup. What it does not do is route offers, rotate landers by rule or distribute clicks. It attributes traffic to your own funnel and hands a cleaner signal to the ad platforms. The full Cometly review has the detail.

What PeerClick is built to do

PeerClick is a cloud ad tracker for affiliates, media buyers and iGaming teams, and it sits in the click path the way Voluum and RedTrack do. You route paid traffic through it, and it ties every visit, click and conversion back to the source, landing page and offer that produced it, then optimizes toward the metric you pick. Its edge over a plain tracker is the Traffic Distribution AI, which re-weights offers, landers and paths every minute toward ROI, earnings per visit or conversion rate, so the winners take more traffic without you touching a dashboard. Tracking is cookieless and server-to-server, with native CAPI to Facebook, Google Enhanced Conversions and TikTok, and it handles the redirect-style flows these buyers actually run: incoming and outgoing postbacks, FTD and RevShare tracking, offer rotation and A/B testing across 100-plus integrations. The PeerClick review covers where it holds up and where it does not.

The one place they touch, and where they split

Both send server-side conversions back to the ad platforms, and if you squint that looks like overlap. It is not. Cometly's conversion is a Stripe-verified revenue event: a trial that became a paid plan, a renewal, an expansion. That is the signal a finance team will defend, and it is what Cometly feeds Meta and Google so the auction optimizes toward paying customers rather than form fills. PeerClick's conversion is an offer action inside a path it is actively routing, a lead, a sale or a first-time deposit, fed back so the auction learns while the same engine shifts traffic toward whichever offer is winning right now. One measures a funnel and improves the ad signal; the other runs the traffic. If your world is a set of offers and creatives you push paid clicks at, PeerClick sees exactly what matters and acts on it every minute. If your world is one SaaS funnel where the money shows up weeks later in Stripe, PeerClick cannot see that revenue and Cometly is built for nothing else.

Which one is you

The fit question is really a business-model question, and it settles the pick. Cometly is the answer if you sell software on subscriptions, your conversions live in Stripe and a CRM, and the number you defend to a board is customer-acquisition cost against ARR rather than cost per click. Be clear-eyed about the trade: it has left the DTC and ecommerce market it once served, there is no public price and no free trial, so you are quoted on a call and cannot test against your own numbers first, and its recurring complaints are support measured in business days and trouble seeing the full pre-purchase journey. PeerClick is the answer for the operator this site is mostly written for: an affiliate, iGaming or performance buyer routing paid traffic to offers, who needs to see which source and lander converted and move budget the same hour. Its costs are different in kind: outside proof is thin, with one Trustpilot review and no G2 footprint, support reads as a coin flip, the Traffic Distribution AI sits on the $199 tier and the anti-fraud kit on the $399 tier, and billing takes no refunds. Neither cost list is a dealbreaker. They are the price of two different tools, and there is no overlap to agonize over: if you are a SaaS marketer Cometly is the serious answer and PeerClick is not in the running, and if you are a media buyer routing offer traffic PeerClick fits the work and Cometly is the wrong shape and the wrong buying model.

When the tracker is only half the problem

Both of these stop at measurement and the ad signal. Neither builds the page the traffic lands on or hosts the checkout that takes the money, and for a lot of paid-traffic operators the leak is on that side of the line, not in the reporting. Two tools worth knowing sit there.

ElasticFunnels is a funnel platform for teams running paid traffic. Its lead feature is same-URL split testing: variants rotate server-side under one campaign link, so Meta, Google and TikTok keep their learning and a test never resets the ad's optimization by pointing traffic at a new address. Around that it builds the pages, hosts the checkout with order bumps, one-click upsells, subscriptions and multi-MID routing, and keeps the click, the order, the rebill and the refund on one data layer with a CRM and attribution, so nobody reconciles four exports to find which angle actually made money. It starts at $97 a month with a 14-day trial that needs no card, every feature is on every plan, and plans differ by traffic. The honest caveat is that it is newer than the platforms on this page and there is very little independent third-party review coverage yet, which is what you would expect of a product this recent, so until you run real volume through it you are largely weighing the vendor's own account rather than a stack of outside reports.

TrackPlay matters if the offer runs on a video sales letter, which neither an attribution platform nor a click tracker can see inside. It is a VSL player and analytics platform that ties every second watched to who actually bought, draws retention per second split into buyers and non-buyers, and posts the cart-verified sale back to Meta, TikTok and GA4 on the play that earned it. It has a no-card free tier of 1,000 plays a month and paid plans from $29 a month. It is narrow by design, though: built for paid-traffic VSL conversion, it is not a general video host or a B2B content library and has none of the channels or webinar tooling of a Wistia, so it is the wrong tool if the video's job is content marketing rather than a direct-response sale.
