Head-to-head
Cometly vs AdsBridge
Two attribution names on one shortlist that answer opposite questions. One ties ad spend to Stripe revenue and CRM pipeline; the other tracks the paid traffic you route to your own landers. Here is which fits which operator.
By Marcus Flynn, tracking and attribution editor. Updated 28 September 2026.
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; pick AdsBridge if you buy paid traffic to landers and offers you run and want a real tracker with a landing page builder in one cheap tool.
Quick answer
AdsBridge is our top pick for most people. AdsBridge bundles click tracking, a landing page builder and Fraud-Guard bot filtering into one cloud tool that starts at $29 a month, which makes it one of the cheapest ways to run a real tracker and hosted landers together. It is legitimate and it has been around since 2013; the honest caveat is that independent proof is thin and its hosted landers lock to its servers.
- Cometly. Best for B2B SaaS teams tying ad spend to Stripe revenue and CRM pipeline.
- AdsBridge. Best for Budget affiliates who want tracking and landing pages in one tool. From $29/mo.

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. Buyers on r/FacebookAds confirm it pushed more matched data to Meta than other trackers they had run.
- 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, and HubSpot and Salesforce lifecycle stages map onto the same touchpoints, 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 instead of writing SQL, and on Enterprise a warehouse sync to Snowflake or BigQuery plus an MCP server that lets an AI agent read your attribution data. 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) and aggregate ratings of 4.8 out of 5 on G2 across 36 reviews and 3.6 out of 5 on Trustpilot across 92.
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. That matters most to affiliate media buyers running many offers through a redirect. A SaaS team sending paid traffic to one funnel does not need routing.
- It has left the DTC and ecommerce market it once served. Cometly's own site now names Triple Whale as the ecommerce tool and positions itself for B2B SaaS. 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 before buying.
- 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, or just want a price before a call, get neither. One G2 reviewer wanted more transparent negotiation and flagged pricing changes over time.
- 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 or getting purchases captured fast enough. The sample is small, but it is consistent enough that you should test response times and event latency during onboarding.
AdsBridge: pros and cons
What works
- Cheap to start: $29/mo for 100,000 visits with a 14-day trial that needs no card, well below what Voluum or RedTrack charge to get going.
- A built-in landing page builder with visual and HTML editors, templates and CDN hosting, so your tracker and your landers live in one tool instead of two subscriptions.
- Cloud-hosted across seven AWS data centers in 160-plus countries, so there is no server to provision, patch or scale like Keitaro or Binom.
- The media-buyer basics are all present: a traffic distribution system with rules, split testing, S2S postbacks, tracking without redirects, and Fraud-Guard bot and proxy filtering.
- It has run under the same company since 2013, so it is an established tracker rather than a new arrival with no history.
What to watch
- Independent proof is thin and dated. G2 lists no reviews, Capterra has a handful, and most affiliate-forum praise is from 2014 to 2019, so you are largely trusting the vendor's own pages.
- Landing pages built in its editor are hosted on AdsBridge and cannot be downloaded, so switching trackers later means rebuilding those pages from scratch.
- Pricing is by monthly visits with per-1,000-visit overage, so a high-traffic pop or native campaign with a low conversion rate can push the real bill well past its tier.
- Cancellations get no refund under its own billing policy, so a mid-cycle change of mind costs you the rest of the month.
- Serious media buyers mostly shortlist Voluum, RedTrack or Keitaro, so there are fewer public setups and recent walkthroughs to copy when you get stuck.
The real differences
What each one actually is
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 multi-touch journey back to the campaign, ad and creative that drove it. Its headline job in 2026 is revenue attribution: a native Stripe integration ties trials, paid conversions, renewals and LTV to the originating ad, and HubSpot and Salesforce lifecycle stages map onto the same touchpoints, right through to closed-won ARR. Comet LLC has tracked paid spend for years, it carries named case studies, and its plans are usage-based on monthly pageviews and quoted on a sales call.
AdsBridge is a cloud click tracker with a landing page builder attached. You point your paid traffic through it, and it routes each visitor to the right lander and offer through its traffic distribution system, records the conversion your network or pixel posts back, and reports by campaign, source and country. On top of the tracker sits a visual and HTML editor that builds and hosts the landers themselves, so a buyer runs tracking, split tests and pages from one login. It has run under the same company since 2013, hosted across seven AWS data centers, and starts at $29 a month.
Do they even compete?
Only at the edges, and that is the honest place to start. Both read conversions, and both can move some signal back toward the ad platforms. Everything else is different. Cometly measures the value of your traffic: it is built for a business that sends paid clicks to a funnel it owns and needs to tie those clicks to real revenue, subscription MRR and pipeline. AdsBridge tracks the traffic itself: it is built for a media buyer routing paid clicks to landers and network offers, who wants to know which campaign, source and country made the sale, cheaply, without a data team.
The gap is starkest on the way in. AdsBridge starts at $29 a month with a 14-day trial that needs no card, so you can point it at a small campaign this afternoon. Cometly publishes no price and runs no free trial: every plan is quoted on a sales call, because, it says, attribution needs setup before it means anything. This site is written for the media buyer routing paid traffic to offers they run, so for most readers here AdsBridge is the tool shaped like the job. The rest of this page is the case for each, because the exception, a B2B SaaS operator, is real and Cometly is built precisely for it.
What actually feeds the ad platforms
This is the axis buyers reach for first, and it is the one place where Cometly is plainly the stronger tool. Its server-side Conversion API sends deduplicated conversions back to Meta, Google, LinkedIn and TikTok, and it reports Meta event match quality as high as 9.3 out of 10 where a hand-rolled pixel often sits at 4 to 5. Buyers on r/FacebookAds say it pushed more matched data to Meta than other trackers they had run. That clean signal is what a smart-bidding algorithm learns from, so better match quality is not a vanity metric. It is more of your conversions arriving to train the bid.
AdsBridge handles the pixels and server-to-server postbacks for the offers you route through it, which tells your affiliate network or your own pixel that a conversion happened. That is enough for a network to reconcile a payout or for a campaign to count sales. But it does not lead with a native platform CAPI feed piping a modeled, deduplicated signal into Meta, Google and TikTok the way Cometly does. If the job is feeding the algorithm the cleanest possible conversion data, Cometly wins this point, and it is worth being clear about that before the fit question decides the page. Neither tool fixes a broken pixel or low event match quality on its own. They report and forward the signal, they do not repair a weak setup.
Where each one earns its place
Cometly's clearest edge is the revenue report. The native Stripe sync ties trials, new customers, recurring revenue and LTV to the ad that drove them, and CRM lifecycle stages ride the same touchpoints through to closed-won ARR. That is the report a SaaS finance team will actually defend in a board meeting, and it is a genuinely different thing from clicks and ROAS. The honest caveats are real. Cometly has left the DTC and ecommerce market it once served and now names Triple Whale for ecom, so an ecommerce brand should demand proof on its own orders first. There is no public price and no free trial, so you buy on a call. And the recurring complaints on r/FacebookAds are about support measured in business days and trouble seeing the full pre-purchase journey, both worth testing during onboarding.
AdsBridge's clearest edge is that pages come in the box. Its visual and HTML editor, templates and CDN hosting live inside the same tool as the tracker, so a buyer without a page stack does not need a second subscription to a funnel builder or separate hosting. It also bundles Fraud-Guard bot and proxy filtering, which matters on pop, push and native traffic where junk clicks are common. The catch is real: landers built in its editor are hosted on AdsBridge and cannot be downloaded, so switching trackers later means rebuilding those pages. Its independent proof is also thin and dated, with no G2 reviews, a handful on Capterra and most affiliate-forum praise from 2014 to 2019, so you are largely trusting the vendor's own pages. And it meters on visits with per-1,000-visit overage, so a high-traffic, low-converting campaign can push the bill past its tier before your conversions do.
Which operator are you?
Pick Cometly if you run a B2B SaaS business and your real pain is that no report ties ad spend to the money. Cometly gives you trials, paid conversions, MRR, LTV and closed-won ARR mapped back to the ad, audience and creative, a server-side Conversion API with event match quality most manual setups cannot reach, and CRM lifecycle stages on the same journey. Its catch is the shape of the purchase: no public price, no free trial, and a sales call before you see a number, plus support and journey-timing complaints worth pressure-testing during onboarding. It is not a route-through tracker, and it has stepped back from ecommerce, so an affiliate or DTC buyer is not its reader.
Pick AdsBridge if you buy paid traffic to landers and offers you run and want a real tracker and hosted pages in one cheap login. Twenty-nine dollars a month, a card-free trial, no server to patch and a page builder included is a low bar to clear, and the media-buyer basics are all there: rule-based traffic distribution, split testing, S2S postbacks and Fraud-Guard. Its catch is the mirror of Cometly's: it records and posts back conversions, but it will not tie a subscription's MRR and ARR to the originating ad, and it does not push a native modeled CAPI signal to the platforms the way Cometly does. Confirm the numbers on a small campaign first, because the independent proof is thin, the hosted landers lock you in, and cancellations get no refund.
For this site's reader, the media buyer routing paid traffic to offers they own, AdsBridge is the practical pick, and Cometly is the wrong shape and the wrong price to test. Flip the operator, though, and the answer flips with it: a B2B SaaS team tying ad spend to recurring revenue wants Cometly, and AdsBridge cannot produce that report at all. The full Cometly review and AdsBridge review go deeper on each, and if you are weighing a route-through tracker against Cometly on the same revenue axis, RedTrack vs Cometly draws the same line.
Changelog

What each one costs
Cometly. Cometly does not publish a price. Every plan is usage-based on monthly pageviews and quoted on a sales call, and Cometly says it runs no free trial because attribution needs setup first. So you cannot see a number, or test it against your own conversions, before you have taken the call. One G2 reviewer wanted more transparent negotiation and flagged pricing changes over time.
AdsBridge. From $29 a month for 100,000 visits, with a 14-day trial that needs no card, well below what Voluum or RedTrack charge to start. Tiers are metered by monthly visits with per-1,000-visit overage, climbing to around $799 a month, so a high-traffic, low-converting campaign can push the real bill past its tier before your conversions do. Cancellations get no refund under its own billing policy, so a mid-cycle change of mind costs you the rest of the month.
