A proven cloud ad tracker against a B2B SaaS revenue attribution tool, and which one your business needs

RedTrack vs Cometly

By Dana Rourke, Lead reviewer. Reviewed by Campaign Buyer Editorial. Updated 23 September 2026.

Quick answer

Pick RedTrack if you buy paid media to offers, landers and ecommerce as an affiliate or media buyer and want click-level ROI, automatic ad-cost sync and server-side CAPI to Meta, Google and TikTok from one account with nothing to install; pick Cometly if you sell B2B SaaS or a subscription and need ad spend tied to Stripe revenue and CRM pipeline, from first click to closed-won, with server-side conversion feeds back to the ad platforms.

If you are down to RedTrack and Cometly, the honest starting point is that these two were built for two different jobs, and for two different kinds of company. Both sit somewhere under the word attribution, but they answer completely different questions. RedTrack is a cloud ad tracker for affiliates and media buyers: it stamps every click, follows it through a lander to an offer, and tells you which source made money. Cometly is a B2B SaaS revenue attribution tool: it ties ad spend to money that arrived in Stripe and to deals in a CRM. The reader stuck between them is really deciding what they buy traffic for, not which product is better made.

RedTrack runs in the cloud with nothing to install, pulls your ad spend in automatically, fires server-side conversion API events back to Meta, Google and TikTok, and tracks affiliate, lead-gen and ecommerce from one account, metered by events from $69 a month billed annually with 2 million events on that entry plan. Cometly also runs in the cloud, but it feeds Stripe revenue and CRM deal stages into its attribution through the Comet Pixel and server-side events, and prices on your monthly pageviews with a quote you get on a sales call. The pricing points the same way the products do: one is a metered tracker for someone buying traffic to offers, the other is a metered fee for a software company that wants its pipeline tied to ad spend.

The one question that decides it: what you buy traffic for

Answer this before you compare a single feature. Do you buy media to offers as an affiliate or media buyer, pushing traffic to landers and offers that may live on domains you do not even own? Or do you sell B2B SaaS or a subscription through a longer, sales-assisted funnel that closes in a CRM weeks after the click? If your problem is seeing which source, campaign, lander and offer produced a profit at click-level, across any traffic type, that is RedTrack's problem to solve. If your problem is knowing which campaign produced a trial that became a paying customer weeks later, and getting that signal back to the ad platforms so they optimize toward revenue instead of raw form fills, that is what Cometly is for.

The business model is not a detail here, it is the decision. RedTrack assumes you run direct-response traffic and want click-level ROI with the modern paid-media plumbing, CAPI and synced spend, working on day one. Cometly assumes a Stripe subscription or a CRM pipeline and a sale that takes weeks, which is why it writes pre- and post-form touch history onto each deal in HubSpot or Salesforce, the part a CRM's own tracking usually cannot see across a long journey. Put a B2B software closed-won question into RedTrack and it has no pipeline to read. Point high-volume affiliate traffic at Cometly and you are metering a revenue-attribution tool on a job it was never built for. Knowing which of those two sentences describes you settles most of the choice.

RedTrack: the proven cloud tracker with the plumbing switched on

RedTrack is the tracker this site ranks first, and the reason is coverage for the price with the modern paid-media plumbing built in rather than bolted on. It runs in the cloud with nothing to host, captures conversions server-side, pulls your ad spend from the platforms automatically so ROI is calculated for you, and fires conversion API events back to Meta, Google and TikTok, all from the $69 a month Builder plan billed annually, which already includes 2 million events. One account tracks affiliate offers, lead-gen forms and ecommerce checkouts, and there is a dedicated ecommerce Brand plan on top, so a buyer running more than one kind of traffic does not need a second tool. That breadth is why it sits at the top of our tracker ranking.

Its edge in this particular matchup is proof. RedTrack has the deepest public record and the largest community in the category, so before you commit you can read honest setup complaints, long-term user reports and real answers to the questions you will hit, and the 14-day trial takes no card, so you can run it against your ad platform's own numbers first. Two caveats worth naming: the setup rewards patience, since first-time users spend real time wiring postbacks and mapping conversions, and because everything is metered by events, a traffic spike can push you into the next tier mid-month, so estimate your real volume before you pick a plan. RedTrack carries an affiliate link on this site, which is disclosed above. The full RedTrack review covers how it holds up.

Cometly: ad spend tied to Stripe and CRM revenue

Cometly does a narrower and, for a software company, more useful thing: it ties ad spend to money that actually arrived. Its Comet Pixel and server-side events feed Stripe revenue and CRM deal stages into the attribution, so you see which campaign produced pipeline and closed-won revenue, with MRR and LTV attached, instead of trusting Meta to grade its own homework. It runs first, last, linear, U-shaped and data-driven models across a long journey, and it sends deal-stage-aware events back to Meta, Google, LinkedIn, TikTok, Microsoft, Reddit and Snapchat through a server-side conversion API on both plans, so bidding optimizes toward paying customers rather than raw leads. Its G2 record is strong and consistent, 4.8 out of 5 across 36 reviews, with praise clustering on tracking accuracy and fast, human support, and one reviewer reported accurate tracking on over $100,000 a month in ad spend.

The two real caveats are commercial, not technical. Cometly publishes no price and offers no free trial: the Core and Enterprise plans are quoted on a sales call, usage-based on your monthly pageviews, and you commit, or at least pay for onboarding, before you see it run on your own traffic. Some buyers report the quote feels high. The honest workaround is to make the live demo prove the tracking on your real numbers first, because that is the only up-front proof you get. Outside its solid but small G2 record the proof thins out, with Trustpilot at 3.6 and no clear Capterra listing, so it is the opposite of RedTrack here, where you can read years of public discussion before you pay. The full Cometly review walks through the setup and the sentiment in detail.

Different jobs, not a better and a worse tool

Underneath the surface, this is not one tool beating another, it is two answers to two different businesses. RedTrack answers which source, lander and offer made money at click-level, for a buyer sending traffic to offers on any domain, and feeds that signal back to the ad platforms. Cometly answers which campaign produced recurring revenue for a software company, and writes it onto the deal in the CRM. Put a solo B2B founder into RedTrack and they get a deep click tracker with no CRM pipeline to tell them which ad produced a paying subscriber weeks later. Point a scaling affiliate's pop or push volume at Cometly and they are metering a revenue-attribution tool for a job RedTrack does at click-level with CAPI and cost sync already switched on.

So the honest tie-break is not features, it is your operation. If you buy media to offers and live or die by click-level ROI and feeding the ad platforms, the SaaS-first attribution tool was never going to serve you. If you sell software or a subscription and need a weeks-long sale tied to the deal in your CRM, the click tracker has no pipeline to read and no revenue layer to attach. Match the tool to how your revenue actually arrives and the rest of the comparison mostly answers itself.

Where the pricing diverges

Neither of these prices on the same axis, so you are not modeling a crossover point, you are comparing two shapes. RedTrack meters events: $69 a month billed annually gets you in, with CAPI, automatic cost sync and 2 million events already included, and the bill climbs as you track more. Because every visit, click, conversion and postback counts as an event, estimate your real volume before you pick a tier, since a spike can push you up mid-month. Cometly does not publish a price at all: its plans are usage-based on monthly pageviews and quoted on a call, so you cannot line its cost up against a competitor before you talk to sales, and there is no free trial to test it first. If a metered cloud bill you can read on the pricing page fits how you work, that points to RedTrack. If you can accept a quote you only see after a demo, that is the friction you take on with Cometly, and the reason to make that demo run on your own data.

Verify both on your real situation. RedTrack's number is public, but events add up faster than plan names suggest on high-volume traffic, so count yours first. Push Cometly for a written quote against your actual monthly pageviews, because usage-based pricing climbs quietly as your traffic grows, and confirm what the paid onboarding includes before you commit.

A third path if you host the funnel yourself

Both of these tools measure traffic to pages and offers that live somewhere else. RedTrack stamps a click and follows it to a lander and an offer you host on another platform, and Cometly reads revenue out of a Stripe account and a CRM that sit elsewhere too. There is a different way to close the same gap, worth naming because it changes where the data lives. ElasticFunnels is a funnel platform for teams running paid traffic that builds the pages and hosts the checkout itself, and keeps its ad-spend and conversion reporting on the same data layer as those pages, the CRM and the sale. Because a sale closes in a checkout it hosts, that conversion is a first-party event it records directly rather than a postback it has to catch, and it fires server-side postbacks to your affiliate networks on purchase, refund, chargeback and renewal, the network-attribution job RedTrack does for click traffic. It also split-tests page variants under one campaign URL, so a test never resets the ad platform's learning. It starts with a 14-day free trial that takes no card, on plans from $97 a month, plus 0.5% of revenue processed through its hosted checkout.

The honest limit that keeps it on its own line rather than in the table: ElasticFunnels is newer than either tool here, and there is very little independent third-party review coverage to check its claims against, so until you run real volume through it you are largely taking the vendor's word for how its reporting and postbacks hold up. That is exactly what you would expect of a platform this recent, where RedTrack has the deepest public record in the tracker category and Cometly a consistent G2 record you can read before you buy. And its reporting covers the funnels it hosts, so an affiliate tracking clicks across offers on other people's domains still needs a dedicated tracker like RedTrack for that traffic, and a B2B SaaS team attributing a sales-led motion that closes in a CRM it runs elsewhere still needs a tool like Cometly. It is an option for the seller who runs their own pages and checkout end to end, not a replacement for either tool.

Which one for you

You buy media to offers as an affiliate or media buyer: RedTrack. Click-level ROI, automatic ad-cost sync and server-side CAPI to Meta, Google and TikTok come from one account with nothing to install, covering affiliate, lead-gen and ecommerce, and you can prove the tracking on your own traffic during the no-card trial. Estimate your real event count first, since a spike can push you into the next tier mid-month.

You sell B2B SaaS or a subscription and need ad spend tied to revenue: Cometly. Stripe and CRM revenue attribution, long-journey multi-touch models and server-side conversion feeds to seven ad platforms are the right fit, as long as you can commit without a public price or a free trial and you make the demo prove the tracking on your own numbers first.

You host your own pages and checkout end to end: look at ElasticFunnels alongside them, with the newness caveat above in mind, and keep a tracker like RedTrack for any traffic that closes on domains you do not host, or Cometly for a software sale that closes in your CRM.

RedTrack takes our default pick here, not because it out-measures Cometly at Cometly's own job, but because more readers who reach this comparison buy media to offers than sell B2B software. On its own turf, a B2B SaaS or subscription company tying ad spend to Stripe revenue and a CRM pipeline, Cometly is plainly the better tool, and we would pick it every time over a click tracker with no pipeline to read. If you are actually weighing attribution tools for a software business rather than a media-buying operation, our Northbeam vs Cometly comparison takes the next step. If you are choosing between cloud trackers, RedTrack vs ClickFlare and our ad tracker ranking are the ones to read next, and BeMob vs Cometly runs this same fork with a cheaper, free-to-start tracker in RedTrack's place.

RedTrack

What works

  • CAPI and server-side postbacks are built in, so conversions reach Meta and TikTok even after the pixel drops them
  • Pulls ad spend from the platforms automatically, so ROI is calculated for you
  • Mid-market pricing: 2M events at $69/mo on annual billing undercuts Voluum for the same job
  • Handles affiliate, lead-gen and ecommerce tracking from one account

What to watch

  • The setup rewards patience. First-time users spend real time wiring postbacks and mapping conversions
  • The interface is dense and looks dated next to newer dashboards
  • Event-based pricing means a traffic spike can push you into the next tier mid-month

Cometly

What works

  • It ties ad spend to money that actually arrived, not to platform-reported conversions. The Comet Pixel and server-side events feed Stripe revenue and CRM deal stages into the attribution, so you see which campaign produced pipeline and closed-won revenue, with MRR and LTV attached, instead of trusting Meta to grade its own homework.
  • Server-side Conversion API to seven ad platforms, on both plans. It sends deal-stage-aware events to Meta, Google, LinkedIn, TikTok, Microsoft, Reddit and Snapchat, so the bidding optimizes toward paying customers rather than raw form fills. The vendor claims Meta event match quality up to 9.3 out of 10.
  • Multi-touch models built for long B2B journeys. First, last, linear, U-shaped and data-driven attribution, with the full pre- and post-form touch history written onto each deal in HubSpot or Salesforce, which is the part a CRM's own tracking usually cannot see across a weeks-long sale.
  • A strong, consistent G2 record. 4.8 out of 5 from 36 reviews, 34 of them five-star, with praise clustering on attribution accuracy, custom-event tracking and fast, human support. One reviewer reported accurate tracking on over $100,000 a month in ad spend.
  • 70-plus native integrations and done-for-you onboarding. Stripe, HubSpot, Salesforce, Close, HighLevel and the major ad platforms connect in minutes, and a specialist wires your stack up, which matters because attribution is only ever as good as its setup.

What to watch

  • No public pricing. The two plans, Core and Enterprise, carry no numbers; pricing is usage-based on your monthly pageviews and quoted on a sales call. You cannot line its cost up against a competitor before you talk to sales, and some buyers report the quote feels high, one G2 review titled bluntly "Not worth of it's price."
  • No free trial. Cometly does not offer one, arguing that attribution needs your CRM and ad platforms wired up first, and sells a paid onboarding instead. So you commit, or at least pay to get set up, before you see it run on your own traffic. Make the live demo show your real numbers, because that is the only proof you get up front.
  • Thin proof outside G2. Trustpilot sits at 3.6 from 92 reviews and flags that only a handful are recent and the sample may not be representative, and there is no clear Capterra listing. The G2 record is good but small, so the trial you cannot take is exactly the due diligence you would most want.
  • It is attribution, so it is directional, not truth. Like every tool in the category, its models will not perfectly match Meta, Google, GA4 and your bank at once, and it is only as accurate as your UTMs and CRM hygiene. Treat its numbers as a better basis for decisions, not a precise ledger.
  • Some rough edges reviewers name. A couple report documentation that lags the actual app, one flags pricing changing after they signed, and a Trustpilot reviewer found it "just another tool with a bunch of complicated options." None is disqualifying, but budget setup time and expect to lean on support early.

Frequently asked questions

RedTrack or Cometly: which should I use?
Pick RedTrack if you buy paid media to offers, landers and ecommerce as an affiliate or media buyer and want click-level ROI, automatic ad-cost sync and server-side CAPI to Meta, Google and TikTok from one account with nothing to install; pick Cometly if you sell B2B SaaS or a subscription and need ad spend tied to Stripe revenue and CRM pipeline, from first click to closed-won, with server-side conversion feeds back to the ad platforms.
Which is cheaper, RedTrack or Cometly?
RedTrack starts at $69/mo, billed annually and Cometly at a quoted, usage-based fee. These two do not price on the same axis, and that tells you who each is for. RedTrack meters events and starts at $69 a month billed annually, with CAPI, automatic ad-cost sync and 2 million events already on that entry plan. Cometly meters your monthly pageviews and quotes on a sales call, with no public number and no free trial. There is no crossover to model. Price each on the business you run, not the entry figure.
Do RedTrack and Cometly do the same thing?
No, and it is the first thing to get straight. RedTrack is a cloud ad tracker: it stamps every click, follows it through your lander to an offer on any domain, catches the conversion server-side, pulls your ad spend in automatically and fires conversion API events back to Meta, Google and TikTok, so a media buyer sees which source, lander and offer made money. Cometly is a B2B SaaS revenue attribution tool: its Comet Pixel and server-side events tie ad spend to Stripe revenue and CRM deal stages, so a software company sees which campaign produced pipeline and closed-won revenue. One reads click-level ROI to offers; the other connects paid spend to recurring revenue in a CRM. They overlap in name only.
Can RedTrack tie ad spend to Stripe revenue and a CRM the way Cometly does?
Not out of the box. RedTrack captures conversions server-side and can read ecommerce revenue values, and it does have an ecommerce Brand plan, but it is a click-level ad tracker, not a revenue-attribution layer over Stripe and a HubSpot or Salesforce pipeline. Following a click through a weeks-long, sales-assisted journey to closed-won, with MRR and LTV written onto the deal, is Cometly's whole reason to exist. If that is the question you need answered, RedTrack is the wrong shape for it.
Can Cometly track high-volume pop, push or native affiliate traffic?
It is not built for it. Cometly is made and marketed for B2B SaaS and subscription companies tying ad spend to Stripe and a CRM, and it prices on your monthly pageviews. Point millions of pop or push clicks at it and you are using a revenue-attribution tool for a redirect-and-postback job it was never designed for, at a cost that meters on the volume. High-volume, direct-response click tracking is RedTrack's territory, not Cometly's.
Which one has more independent proof I can check before I buy?
RedTrack, clearly. It has the deepest public record and the largest community in the tracker category, so setup answers, honest complaints and long-term user reports are easy to find before you commit, and it offers a 14-day trial with no card to run against your ad platform's own numbers. Cometly's proof is a strong but small G2 record, 4.8 from 36 reviews, and it thins out elsewhere with Trustpilot at 3.6 and no free trial, so the demo you sit through is most of the up-front proof you get. Make that demo run on your real numbers.
