BeMob vs Keitaro

If your shortlist is down to BeMob and Keitaro, the good news is that these two really are trying to do the same job. Both are click trackers for people who buy paid traffic: they stamp a click, follow it through your landing page to an offer, catch the conversion, and tell you which source, lander and offer made money. So this is not a question of which tool is built for a different reader. It is a question of how you want to run your tracking, and at what scale.

The split is hosting and volume. BeMob is a cloud tracker you log into, with a genuinely free tier to start on. Keitaro is a self-hosted tracker and traffic router you install on your own Linux server, with a flat license and no cap on events. One asks nothing of you but a login and, past a point, a monthly bill that grows with your events. The other asks you to run a server, and in return never meters a single click.

The one question that decides it: volume, and whether you will run a server

Answer this before you compare a single feature. Are you newer to tracking or spending lightly, and want to prove the workflow without spending or installing anything? Or do you push real volume, want to own your data outright, and refuse to pay a tax on every event? The first buyer belongs on BeMob. The second belongs on Keitaro. Almost everything else follows from that.

BeMob's free plan is not a crippled demo. It gives you 100,000 events a month, 10 campaigns, real landing-page and offer management, and reporting good enough to learn how postbacks and tokens actually work. For a buyer validating their first funnels, that is the right place to make mistakes before money is on the line, and it is the single sharpest reason to pick it here: Keitaro has no free trial at all, so trying it properly means buying a license. But BeMob counts every impression, visit and postback as an event, so the free allowance vanishes fast on impression-heavy traffic, and custom tracking domains only start on its $249-a-month Business plan.

Keitaro answers the opposite instinct. Its maker, Apliteni, has shipped it for years and says more than 4,000 businesses run it, and what those businesses reach for is the routing engine and the ownership. There is no click cap and no per-event meter, the license is flat, and your data lives on hardware you control. The cost is operational: you rent a clean Linux VPS, patch it, and own uptime and scaling yourself. If running a server is not your thing, that cost is real and it is yours.

BeMob: the free on-ramp into tracking

BeMob is the tracker to start on. Nothing to install, a cheap paid entry at $49 a month for a million events, and a free tier that lets you wire up real postbacks and prove a funnel converts before you commit a budget. Because it is cloud-hosted, there is no server to maintain and no operations skill required to keep tracking online. For the buyer whose first question is whether they can test this before they pay, BeMob is the honest answer on this page.

Its limits are the flip side of that convenience. Events are metered, so the bill climbs as you scale, and past testing it is shallower than a self-hosted tracker on routing depth. Custom domains, which most serious buyers want early to keep their tracking off a shared subdomain, sit behind the $249 Business plan. And its conversions go back to your affiliate networks by postback rather than to the ad platforms by CAPI, which is the right shape for a network affiliate and the wrong one for a buyer who lives on Meta's or Google's conversion API. The full BeMob review covers where the free tier stops being enough.

Keitaro: routing depth and a license you own

Keitaro puts its weight on routing and ownership. It splits visitors to different landing pages and offers across 35+ tracking parameters, by geo, device, OS, browser, connection and source ID, and it fires server-side postbacks, sends conversions back to Meta, Google and TikTok through their APIs, and pulls ad spend in for real cost and ROI, all on every individual plan rather than gated behind a top tier. It also bundles a landing page editor, custom domains with SSL and bot filtering, so fewer separate tools sit between your tracker, your lander and your offer. For a buyer whose edge is routing logic and who wants uncapped tracking on data they own, that combination is the whole draw, and on that ground we would take Keitaro over BeMob every time.

The costs are operational and real. It is self-hosted only, with no cloud version: you supply and maintain the VPS (CentOS 9 or 10 Stream, 4GB RAM minimum), and there is a learning curve across DNS, SSL, Cloudflare and postback debugging. There is no free trial, though a public live demo and a refund policy soften the commitment. Support is the mixed note. Long-term users praise it as fast, knowledgeable and cheap against cloud trackers, but the sharpest critical review reports 502 errors on server-side conversion tracking and inaccurate cost attribution, with support acknowledging the problem but giving no timeline for a fix, which for a media buyer means daily lost optimization while it is open. Live chat also runs business hours, roughly 06:00 to 16:00 GMT on weekdays, so a launch that breaks overnight in your timezone waits for the next window. The full Keitaro review goes through the routing depth and the support record in detail.

The trade-off, plainly

This is not one tool beating the other on merit. It is convenience and a free start against ownership and no meter. BeMob gives you a login, a free tier and nothing to run, at the cost of event-based pricing and shallower routing once you scale. Keitaro gives you deep routing, uncapped tracking and full control of your data, at the cost of running and maintaining the server it lives on. Put a first-week affiliate onto Keitaro and they buy a license and a VPS to learn a workflow BeMob would have taught them for free. Point millions of clicks at BeMob and the event meter and the $249 domain gate start to look like a tax that Keitaro's flat license simply does not charge.

So the honest tie-break is your operation, not a feature checklist. If you are still learning, spending lightly, or you never want to touch a server, the free cloud tracker was always the right call. If you push serious volume and want to own the stack, the self-hosted router is worth the operations work, and BeMob's metering was going to catch up with you anyway.

Where the pricing diverges

The two do not meter on the same axis, and that itself tells you who each is for. BeMob is free for your first 100,000 events, then $49 a month for a million, so your cost tracks your volume and you can start at zero. Keitaro is a tiered license: €40 a month for Individual Starter, €72 for Advanced, €104 for Expert, then €200 and €400 for its Business Team and Enterprise plans, with six- and twelve-month terms taking 10% and 20% off, and no event cap on any of them. There is no clean crossover to calculate, because one price grows with events and the other does not move at all. Remember that Keitaro's license is not the whole bill either: a VPS to run it, and the time to keep it patched and fast, are part of the cost even though they never appear on the vendor's invoice.

A third path if you host the funnel yourself

There is a third answer worth naming, because neither BeMob nor Keitaro builds or hosts the funnel it measures. Both follow clicks to pages and offers that live somewhere else. ElasticFunnels owns that middle instead. It is a funnel platform for teams running paid traffic that builds the pages, hosts the checkout, and keeps its ad-spend and conversion reporting on the same data layer as the 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, and it fires server-side postbacks to your networks on purchase, refund, chargeback and renewal from that checkout, which is the tracking-and-feeding job both trackers here do, on one system rather than a tracker bolted onto a separate funnel builder. 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.

Two honest limits keep it on its own line rather than in the head-to-head. ElasticFunnels is newer than both tools 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: BeMob has a longer public track record, and Keitaro a long support record and more than 4,000 businesses to read about before you buy. Its reporting also covers the funnels it hosts, so a buyer tracking clicks across offers on domains they do not own still needs a tracker like BeMob or Keitaro for that traffic. And Keitaro's whole appeal is that you own the server and the data, while ElasticFunnels is hosted software you rent, so the buyer who chose self-hosting specifically to keep everything on their own infrastructure is trading that away here. It is an option for the seller who runs their own funnel and checkout end to end, not a replacement for either tracker.

Which one for you

You are newer to tracking or spending lightly: BeMob. The free tier, the cheap $49 entry and nothing to install make it the right place to learn postbacks and prove your first funnels, as long as you watch the event meter and know custom domains wait for the $249 plan.

You buy paid traffic at volume and want to own the stack: Keitaro. Granular routing across 35+ parameters, CAPI and cost sync on every plan, uncapped tracking and full ownership of your data are the right call, provided you can run and maintain the Linux server it lives on and can live with business-hours support.

You host your own funnel and checkout end to end: look at ElasticFunnels alongside them, with the newness and the rented-not-owned caveats above in mind, and keep BeMob or Keitaro for traffic that closes on domains you do not own.

BeMob takes our default pick, not because it out-tracks Keitaro at volume, but because more readers who reach this specific comparison are the newer or lighter-spending buyer BeMob is built for than the high-volume operator who will happily run their own server. A buyer weighing a free cloud tracker against a self-hosted license almost always belongs at the cloud end of that line today. On its own turf, a high-volume buyer who wants deep routing and owned data, Keitaro is plainly the stronger tool, and we would pick it every time for that operator. If you are actually choosing between two self-hosted trackers, our Binom vs Keitaro page takes the next step, and our BeMob vs CPV Lab Pro and ClickFlare vs BeMob comparisons run this same cloud-versus-self-hosted fork against BeMob's other rivals.
