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.

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, posts it back to your networks, and syncs ad spend 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 agree: Northbeam is hosted software with a four-figure monthly floor, and Keitaro is a license you run yourself for a small fraction of that.

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 writing the exact rule that sends the right visitor to the right lander, that is what Keitaro is for.

Northbeam's entry price is high, and by the most common complaint about it, 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. Without heavy multi-channel spend and someone to own the data, most of Northbeam goes unused. Without real volume or the skills to run infrastructure, Keitaro's cheap uncapped tracking is wasted.

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 mixes deterministic clicks with modeled view-through data and runs three kinds of analysis over them. For a brand spending across several channels, that is a fuller picture than a tracker or a Shopify-first dashboard gives you, because it tries to say where the whole budget should go.

Adoption is where Northbeam buyers struggle. Professional sits well above the entry tier, so it only makes sense above a real spend threshold, and 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, the subscription buys little. Northbeam pays off 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. Every individual plan returns conversions to Meta, Google and TikTok through their APIs and pulls ad spend in for real cost and ROI. 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, that combination is the draw, and on that ground we would take Keitaro over Northbeam without hesitation.

Running it is on you, because Keitaro is self-hosted only, with no cloud version. You rent and maintain a Linux VPS (CentOS 9 or 10 Stream, 4GB RAM minimum) and keep it fast, patched and online, and there is a learning curve across DNS, SSL, Cloudflare and postback debugging. You buy a license without a trial, though a public live demo and a refund policy soften the commitment. Support gets mixed marks: long-term users praise it as fast and knowledgeable, but the sharpest critical review reports 502 errors on server-side conversion tracking and inaccurate cost attribution with no timeline for a fix, and live chat runs roughly 06:00 to 16:00 GMT on weekdays. The full Keitaro review goes through the routing depth and the support record in detail.

Two questions, two tools

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 for models they cannot staff. Put a large brand's channel-mix question into Keitaro and it cannot see it, because a click tracker was never built to answer it.

A brand with real multi-channel spend and an analyst will not get a budget-allocation answer from a tracker. A buyer running serious volume who wants to own the stack and control the routing would be paying a modeling platform priced for a much bigger company, and moving their data onto someone else's servers, the opposite of what they came for.

Where the pricing diverges

The two sit at opposite ends of the market, and that alone tells you who each is for. Northbeam's two published tiers are priced for a brand where reallocating spend more accurately is worth many times the fee. Keitaro is a ladder of Individual and Business plans, with six- and twelve-month terms taking 10% and 20% off. There is no crossover to calculate the way there is between two cloud trackers. If Northbeam's entry fee sounds absurd for your situation, it was built for someone else, and if you need a channel-mix model, Keitaro was never going to provide one.

Northbeam's sales team will size the quote against your spend. Keitaro's license is only part of its cost: the VPS and the hours to maintain it never appear on the vendor's invoice, and most volume buyers land a few tiers above the entry plan once they need more domains and seats.

A third path if the funnel is yours to host

A brand or buyer who sells a product of their own has a third choice between a modeling platform and a tracker. ElasticFunnels is a funnel platform for teams running paid traffic: it builds the pages, hosts the checkout, and keeps ad-spend and conversion reporting on the same data layer as the CRM and the sale. A sale in its checkout is recorded directly, and it sends server-side postbacks to your networks on purchase, refund, chargeback and renewal, which covers the tracking job Keitaro does and a slice of Northbeam's reporting on one system. 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.

Its main drawback is age. ElasticFunnels has very little independent review coverage, so until you run real volume through it you are taking the vendor's word on how its reporting and postbacks hold up, which is normal for a platform this recent and a contrast with Northbeam's years of public setups and Keitaro's 4,000-plus businesses. It reports on the funnels it hosts, so cross-channel modeling for stores run elsewhere still needs Northbeam, and traffic to other people's domains still needs Keitaro. It is also hosted software you rent, so a buyer who chose Keitaro to keep everything on their own server gives that up here.

Which one for you

You spend heavily across channels and have a data owner: Northbeam. Multi-touch attribution, media-mix modeling and incrementality earn the subscription 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 maintain the Linux server it lives on and 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 is our default pick because more readers who reach this specific comparison are the high-volume paid-traffic buyer it is built for than the funded DTC brand with an analyst that Northbeam requires. A buyer weighing a self-hosted license against a four-figure modeling platform almost always belongs at the tracker end of that line today. For 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, our Binom vs Keitaro page takes the next step, and our Northbeam vs CPV Lab Pro and Northbeam vs Binom comparisons set Northbeam against the other self-hosted trackers.
