Binom vs Cometly

What each one actually is

Binom is a self-hosted performance-marketing tracker for affiliates and media buyers. You install it on your own server, route ad clicks through it, and read conversions back from affiliate networks through server-to-server postbacks. Around that sit the things a high-volume buyer lives in: click routing with paths and rules, offer and lander rotation, reports up to five grouping levels deep, sub-ID tracking and built-in cloaking. It calls itself "the tracker for professionals", and the thing you buy is a license to run software yourself, not an account someone else runs.

Cometly is a marketing attribution platform, and in 2026 it is built for B2B SaaS. You install its Comet Pixel with one line, it captures every visitor cookielessly and across devices, records conversions server-side so ad blockers and iOS restrictions do not drop them, and models the multi-touch journey back to the campaign, ad and creative that drove it. Its headline job is revenue attribution through Stripe: a native 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. Its own site puts the split plainly: "Stripe knows who pays. Ad platforms only know who clicks. Cometly stitches the two together, so every trial, paid conversion, and renewal flows back to the ad, audience, and creative that drove it."

So the first thing to be honest about is that these are not the same category. Binom moves clicks through a redirect and reads network postbacks; Cometly reads your own funnel and your Stripe account. A buyer down to exactly these two is usually deciding between two different jobs, not two versions of one. Get the job right and the tool follows.

The one place they overlap is conversion feedback, and it is not a tie

Both tools can send server-side conversions back to the ad platforms, which is the one axis where they genuinely compete. On most cross-class pairs that axis reads as a rough tie. Here it does not. Cometly's Conversion API is its strongest feature: it sends deduplicated conversions to Meta, Google, LinkedIn and TikTok and reports Meta event match quality up to 9.3 out of 10 against a manual setup that sits around 4 to 5. Binom's server-side conversion API is limited by comparison, with Facebook and Google integrations in its first version and the second still catching up. So on the narrow question of feeding the ad platforms clean first-party data, Cometly is ahead, and if that loop is the whole reason you are shopping, that settles it.

That is one axis, though, and it points the opposite way to the others. Binom's job is not to feed the platforms a corrected revenue signal; it is to route and measure clicks at volume on flows where you often cannot drop a browser pixel on someone else's page, which is exactly where a postback model holds up and a pixel does not. Weigh the conversion-feedback edge against what each tool is built to do before you let it decide.

What Binom does that Cometly will not

Binom routes traffic. You point a campaign at your tracker, split clicks across prelanders and offers by rule, rotate creatives, and read five-level reports on native, push, pop and search inventory, with cloaking built in and bot filtering available as a paid module. Conversions come back server-to-server from the network, which is the model that survives on redirect-style affiliate flows. Cometly does none of that, and says so: its own record notes it "does not rotate offers, split traffic across landers by rule, or distribute clicks the way Voluum, RedTrack or Binom do." For an affiliate or media buyer running many offers through a redirect, that is not a small gap. It is the whole job, and Cometly is not the tool for it. If routing at volume is what you need, weigh Binom against a like-class tracker in Binom vs FunnelFlux Pro rather than against Cometly.

What Cometly does that Binom will not

Cometly models recurring revenue. Its native Stripe sync ties trials, new customers, MRR, ARR and LTV to the ad that produced them, and HubSpot or Salesforce lifecycle stages map onto the same touchpoints, so a SaaS team can read spend against MQL, SQL, opportunity and closed-won ARR. Around that sit a cookieless pixel with cross-device identity, 70-plus native integrations and, on Enterprise, a warehouse sync to Snowflake or BigQuery. Binom carries none of this. It is a click tracker, not a revenue-attribution layer for subscription businesses; it tells you which click converted, not which ad grew your ARR. A B2B SaaS operator whose budget question is ad spend against Stripe revenue is describing Cometly, and the closest like-class comparison for that buyer is Hyros vs Cometly, not this one.

Hosting, cost and how you buy

Binom is self-served on price and self-run on infrastructure. You can see the license fee, start a full-feature 14-day trial (extendable to 30 on request) and buy without a call. The catch is the server. Binom's own install docs require a clean VPS or dedicated box (Ubuntu, 4 GB of RAM, two cores, 50 GB of disk, KVM) and warn that stability is not guaranteed if you alter it. Support installs the tracker on a fresh server for free, but from there the domains, backups, monitoring and uptime are yours. The real cost is total ownership, not the license line.

Cometly is the opposite on every count. There is nothing to host, and setup runs in hours with an onboarding specialist rather than a server build. But there is 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 has to be set up before it can be judged. So you trade Binom's self-serve start and flat, visible license for a managed cloud you cannot test against your own numbers until you have bought it.

Who each one is for

Binom fits the high-volume affiliate and media buyer who is comfortable running infrastructure. Network offers, CPA and lead-gen across native, push, pop and search, several traffic sources rotated and tested on the click, built-in cloaking, and a click count high enough that event-priced SaaS turns into a four-figure monthly line: that is where a flat license and your own server pay off. Below that volume it is overkill, and the reader who wants the detail should read the full Binom review or scan the alternatives to Binom.

Cometly is the fit when you run a B2B SaaS business and the report that decides your budget is ad spend against Stripe revenue and CRM pipeline, right through to closed-won ARR. Its Conversion API and cookieless pixel are a genuine strength there, and if that is your business it is worth a demo. Note, though, that Cometly has left the DTC and ecommerce market it once served, and reviewers report weaker matching on cash-on-delivery and email-less orders, so an ecom brand should demand proof on its own orders. The full Cometly review and the alternatives to Cometly have the rest.

Two caveats close it out. If your business is a scaled direct-to-consumer store rather than an affiliate operation or a SaaS, neither of these is really your tool, and cross-channel measurement suites are the shape to look at instead: the whole field is on the best ad tracking and attribution software page. And neither tool fixes a weak offer, a broken pixel setup or low event match quality. They make the numbers clearer. They do not make the funnel better.

Binom publishes a flat license that does not climb with clicks. The self-hosted v2 tracker is $149 a month, or $104 a month billed yearly, and the vendor rates it at up to 260 million clicks a day for the same price. A managed Binom Cloud plan is $299 a month, an extra license is $75, and the Binom Protect bot and cloaking module is a separate add-on. On top of any of those you carry the server it runs on, so budget for a VPS or dedicated box, domains, backups and uptime. There is a full-feature 14-day trial, extendable to 30 on request, and you can buy without a sales call.

Cometly publishes no price. It runs two plans, Core and Enterprise, priced on your monthly pageviews rather than your ad spend, with annual billing about 20% cheaper than monthly, and both are quoted after a demo. There is no free trial: Cometly pairs you with an onboarding specialist and says attribution has to be set up before it can be judged, so you cannot test it against your own numbers before you pay. Enterprise adds the warehouse sync to Snowflake or BigQuery, an MCP server and API access.

The two do not really trade off on a single number, because one is a visible flat license plus a server you run and the other is an opaque usage quote with nothing to host. The figure that decides it is not one price against the other. It is whether you are routing paid traffic through a tracker at volume, which is Binom, or tying recurring Stripe revenue back to ads, which is Cometly.
