Northbeam vs Keitaro

If you are down to Northbeam and Keitaro, the first thing worth saying is that these two rarely measure the same thing. Both help you see which of your ads actually made money, but they were built for two different operations at two very different prices. Northbeam is a modeled attribution and media-mix platform for a high-spend DTC brand. Keitaro is a self-hosted tracker and traffic router for a paid-traffic buyer who wants to own the data, route visitors by hand, and skip per-event billing. The reader stuck between them is really deciding what kind of operation they run, not which product is better made.

Northbeam blends first-party click data with modeled and deterministic view-through data, then layers multi-touch attribution, media-mix modeling and incrementality testing on top, so a brand spending across Meta, Google and TikTok can decide where the next dollar goes. Keitaro sits on your own Linux server, stamps a click, routes the visitor to the right lander and offer, catches the conversion, fires server-side postbacks to your networks, and syncs ad spend back for real cost and ROI. One models the whole media mix for a brand. The other tracks and routes the clicks for a buyer, on hardware you control. The price tags say the same thing: Northbeam starts at $1,500 a month as hosted software, Keitaro starts at €40 a month for a license you run yourself.

The one question that decides it: what you run

Answer this before you compare a single feature. Are you a brand allocating heavy spend across several channels, or a buyer routing and tracking campaigns at volume? If your problem is deciding how to split a large budget across Meta, Google, TikTok and more, and proving whether a channel is genuinely incremental, that is Northbeam's problem to solve. If your problem is knowing which click, source and offer produced a conversion, and expressing the exact rule that sends the right visitor to the right lander, that is what Keitaro is for.

The scale gap is the decision, not a detail. Northbeam has a floor of $1,500 a month and, by the most common complaint about it, needs a dedicated analyst to run the models and act on them, or it becomes expensive shelfware. Keitaro is a tiered license with no click cap, but it assumes you are comfortable running a server: you supply the VPS, patch it, and own uptime and scaling yourself. If you do not have heavy multi-channel spend and someone to own the data, most of Northbeam goes unused. If you do not push real volume or cannot run your own infrastructure, its cheap uncapped tracking is wasted on you. Knowing which of those two sentences describes you settles it.

Northbeam: modeled attribution for a high-spend brand

Northbeam is the tool you graduate to when a percentage point of attribution accuracy is worth thousands of dollars in reallocated spend. It blends first-party clicks with modeled and deterministic view-through data, and layers multi-touch attribution, media-mix modeling and incrementality on top. For a brand spending across several channels, that is a genuinely fuller picture than a tracker or a Shopify-first dashboard gives you, because it is trying to answer where the whole budget should go, not just which link fired.

That reach has a floor and a cost of ownership. Pricing starts at $1,500 a month and rises to $3,500 for the Professional tier, so it only makes sense above a real spend threshold. The bigger risk is not the price, it is adoption. The most common complaint is onboarding: one G2 reviewer described paying for Northbeam and being unable to get it usable. Without an analyst to run the models and act on them, it becomes expensive shelfware. Northbeam earns its keep for a brand that has both the spend and the person to own it, and we rank it second in our ecommerce attribution ranking for exactly that buyer. The full Northbeam review covers how the modeling holds up in practice.

Keitaro: routing depth, native cost sync, and a cheaper way in

Keitaro does the tracker's job and puts its weight on routing and breadth. Its maker, Apliteni, has shipped it for years and says more than 4,000 businesses run it, and the thing those businesses reach for is its filtering engine. 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 the 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 a cheaper way in than a modeling platform, that combination is the whole draw, and on that ground we would take Keitaro over Northbeam without hesitation.

Its costs are operational, and they are real. It is self-hosted only, with no cloud version: you rent and maintain a Linux VPS (CentOS 9 or 10 Stream, 4GB RAM minimum), keeping it fast, patched and online is your job, and there is a learning curve across DNS, SSL, Cloudflare and postback debugging. There is no free trial either; you buy a license, though a public live demo and a refund policy soften the commitment. The mixed note is support. 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. Like every tracker, it answers a narrower question than Northbeam: it tells you which click, source and offer converted, but it does not model your media mix or test incrementality across channels.

Different jobs, not a better and a worse tool

Underneath the price gap, this is not one tool beating another, it is two answers to two different questions. Northbeam answers where your next budget dollar should go across every channel, with modeling that only pays off at heavy spend and only if someone runs it. Keitaro answers which click, source and offer made money, and lets you route each visitor by hand, for a buyer who wants to own that data outright and refuses to pay a tax on every event. Put a solo affiliate into Northbeam and they pay $1,500 a month for models they cannot staff. Put a large brand's media-mix question into Keitaro and it cannot see it, because a click tracker was never built to answer it.

So the honest tie-break is not features, it is your operation. If you are a brand with real multi-channel spend and an analyst, the tracker was never going to answer your budget-allocation question. If you are a buyer running serious volume who wants to own the stack and control the routing, the modeling platform is priced and staffed for a company you are not yet, and it takes your data onto someone else's servers, which is the opposite of what you came for.

Where the pricing diverges

The two do not price on the same planet, and that itself tells you who each is for. Northbeam opens at $1,500 a month and climbs to $3,500 for Professional, priced for a brand where reallocating spend more accurately is worth many times that. Keitaro is a ladder: €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. There is no crossover to calculate here the way there is between two cloud trackers. The gap is the point: if $1,500 a month for measurement sounds absurd for your situation, that is a signal Northbeam is not built for you, and if you need media-mix modeling and incrementality, Keitaro was never going to provide it at any price.

Read both on your real situation. Verify Northbeam's number with their sales team, because the entry tier assumes a spend level. And remember Keitaro's license is not the whole cost: a VPS to run it, and the time to maintain it, are part of the bill even though they never appear on the vendor's invoice, and the €40 entry is the floor, not the tier most volume buyers land on once they need more domains and seats.

A third path if the funnel is yours to host

There is a third answer worth naming, because neither of these tools builds or hosts the funnel it measures. Northbeam models attribution across channels that live elsewhere, and Keitaro follows clicks to pages and offers hosted 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 Keitaro does and a slice of the reporting job Northbeam does, on one system rather than three. 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 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: Northbeam has years of public setups behind it, 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 brand measuring paid media across channels and stores it runs elsewhere still needs a platform like Northbeam for that job, and a buyer routing traffic that closes on other people's domains still needs a tracker like Keitaro for that traffic. One more contrast is worth being straight about: 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.

Which one for you

You spend heavily across channels and have a data owner: Northbeam. Multi-touch attribution, media-mix modeling and incrementality are worth the $1,500 floor once a percentage point of accuracy moves real budget, provided you have the analyst to run the models and act on them.

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, a built-in lander editor and bot filtering, uncapped tracking and full ownership of your data are the right call, as long as 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 Northbeam for cross-channel media-mix questions or Keitaro for traffic that closes off your own domains.

Keitaro takes our default pick, not because it out-measures Northbeam, but because more readers who reach this specific comparison are the high-volume paid-traffic buyer Keitaro is built for than the funded DTC brand with an analyst that Northbeam requires. A buyer weighing a self-hosted license they run themselves against a $1,500-a-month modeling platform almost always belongs at the tracker end of that line today. On its own turf, a high-spend brand with a data owner, Northbeam is plainly the more capable tool, and we rank it second in our ecommerce attribution ranking for exactly that buyer. If you are actually choosing between two self-hosted trackers rather than a tracker and a platform, our Binom vs Keitaro page takes the next step, and our Northbeam vs CPV Lab Pro and Northbeam vs Binom comparisons run this same fork against the other self-hosted trackers.
