Quick answer

Pick RedTrack if you buy paid media for affiliate offers, landers and ecommerce 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.

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, billed by the events you track. 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 bases its price on your monthly pageviews, quoted by its sales team. RedTrack is a metered tracker for someone buying traffic for offers. Cometly is a quoted service for a SaaS seller 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 traffic for affiliate offers, sending it 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 ad led to 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.

How you earn decides it. 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 CRM data to work from. Send high-volume affiliate traffic through Cometly and you pay pageview-based fees for redirect work 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 with the modern paid-media plumbing built into the core product. 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. One account tracks affiliate offers, lead-gen forms and ecommerce checkouts, with a free Relay plan and a Brand plan for stores and Solo as the first affiliate plan at 5 million events, 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 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. Setup rewards patience, since first-time users spend real time wiring postbacks and mapping conversions. Because everything is metered by events, a traffic spike adds overage per thousand events to the month's bill, 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 subscription business, 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 ads brought in 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 to Meta, Google, LinkedIn, TikTok, Microsoft, Reddit and Snapchat through a server-side conversion API on both plans, so bidding optimizes toward paying customers. 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.

Cometly is harder to buy than to use. It publishes no price and offers no free trial: the Core and Enterprise plans are quoted by its sales team, usage-based on your traffic, 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. Insist on a live demo with your real numbers, because that is the only up-front evidence you get. Outside its solid but small G2 record the proof thins out, with Trustpilot at 3.6 and no clear Capterra listing, the reverse of RedTrack, where years of public discussion are there to read before you pay. The full Cometly review walks through the setup and the sentiment in detail.

Two answers for two kinds of business

Each tool answers a different owner's question. 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 ads produced recurring revenue for a SaaS team, and writes it onto the deal in the CRM. A solo B2B founder on RedTrack gets a deep click tracker with no CRM pipeline to tell them which ad produced a paying subscriber weeks later. A scaling affiliate on Cometly pays pageview-based fees for a job RedTrack does at click-level with CAPI and cost sync already switched on.

So your operation breaks the tie. If you run affiliate campaigns 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

The two are billed on different measures, so there is no crossover point to model, only two shapes to compare. RedTrack meters events: stores can start on the free Relay plan, affiliate buyers start on Solo, and the bill climbs through Team and Enterprise as you track more, with overage per thousand events on top. Because every visit, click, conversion and postback counts as an event, estimate your real volume before you pick a tier. Cometly does not publish a price at all: its plans are usage-based and quoted once you have seen a demo, so you cannot line its cost up against a competitor before you talk to sales, or test it before you buy. 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 once sales has called you, that is the friction you take on with Cometly.

Count your own usage before either bill. RedTrack's tiers are public, but events add up faster than plan names suggest on high-volume traffic. Ask Cometly for a written quote against your actual monthly pageviews, because usage-based pricing climbs as your traffic grows, and ask 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 at the moment of purchase, and it reports purchases, refunds, chargebacks and renewals to your affiliate networks from the server, 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.

Being new is its main limitation. ElasticFunnels is younger 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 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. Its reporting also covers only 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 an outside CRM still needs a tool like Cometly. It suits the seller who runs their own pages and checkout end to end, next to either tool.

Which one for you

You buy paid traffic for affiliate offers: 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 check the numbers against your own traffic during the no-card trial. Estimate your real event count first, since a spike adds overage to the bill.

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 is our default pick here because more readers who reach this comparison buy traffic for 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 that never sees a deal. If you are actually weighing attribution tools for a software business, 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
  • Every paid plan carries CAPI, ad-spend sync and Stop Rules, from Solo at $141/mo on annual billing with 5M events
  • 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

  • Ad spend is matched to revenue that reached Stripe. 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.
  • 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. 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, so you cannot line its cost up against a competitor before you talk to sales. Some buyers report the quote feels high, one G2 review titled bluntly "Not worth of it's price."
  • Cometly offers no free trial, arguing that attribution needs your CRM and ad platforms wired up first, and sells a paid onboarding instead. You commit, or at least pay to get set up, before you see it run on your own traffic, which makes the live demo the one look at your real numbers 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.
  • Its models will not perfectly match Meta, Google, GA4 and your bank at once, and its accuracy depends on your UTMs and CRM hygiene. Use its numbers to choose where the next dollar goes, and reconcile them against a second source.
  • 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.

Pricing

RedTrack: from free, then $83/mo. Affiliate and lead-gen plans are priced by events and seats. Solo is $141/mo billed yearly ($169 monthly) with 5M events and one user. Team is $333/mo ($399 monthly) with 20M events and five users. Enterprise is $833/mo ($999 monthly) with 75M events and fifteen users. Overage costs $0.04 per 1,000 events on Solo, $0.035 on Team and $0.025 on Enterprise, and tracking keeps running past the cap. Ecommerce plans are priced by tracked revenue: Relay is free with UTM-based last-click attribution, Brand starts at $83/mo billed yearly ($99 monthly) and Agency at $499/mo ($599 monthly). Faster ad-spend sync is a paid add-on. Paid plans start with a 14-day free trial.

Cometly: from a quoted, usage-based fee. Cometly quotes every plan on a sales call. Core and Enterprise are both priced on monthly pageviews, which the vendor estimates at about 1.5 times sessions. No figures are published. Billing is monthly or annual, and annual saves 20%. There is no free trial, and a paid Professional Onboarding takes its place. One buyer publicly reported a $600 a month quote.

Frequently asked questions

Which is cheaper, RedTrack or Cometly?
On entry price, RedTrack comes in at free, then $83/mo 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: stores can start on a free plan, affiliate plans start with Solo at 5 million events, and usage past your plan is billed per thousand events while tracking keeps running. Cometly meters your monthly pageviews and quotes after a demo, with no public number and no free trial. There is no crossover to model. Size each against the business you run.
Do RedTrack and Cometly do the same thing?
No. RedTrack tracks clicks to offers, imports ad spend and feeds conversions to Meta, Google and TikTok, so a media buyer sees which traffic paid. Cometly links ad spend to Stripe payments and CRM deals for a software or subscription seller.
Can RedTrack tie ad spend to Stripe revenue and a CRM the way Cometly does?
It reads ecommerce revenue values and offers a store plan, but it has no Stripe or HubSpot pipeline view and writes nothing onto a deal. A weeks-long, sales-assisted sale belongs in Cometly.
Can Cometly track high-volume pop, push or native affiliate traffic?
It was designed for SaaS funnels and bills by pageviews, so millions of pop or push clicks would run up the bill for redirect work it was never meant to do. RedTrack is built for that traffic.
Which one has more independent proof I can check before I buy?
RedTrack, with the largest community among trackers and a 14-day trial that needs no card. Cometly has 36 G2 reviews averaging 4.8, 3.6 on Trustpilot and no trial, so its demo is most of what you can check.
