Hyros vs Keitaro
By Marcus Flynn, tracking and attribution editor. Updated 23 September 2026.
You are down to two, and they are not really the same kind of tool. Hyros is a revenue-attribution layer for a funnel you own: it stitches a buyer's touches together across ads, email, webinars and sales calls, then feeds the real sale, including the one that lands weeks later, back to Meta and Google. Keitaro is a self-hosted click tracker you run on your own server, built to route paid traffic, split-test it and read conversions back through postbacks. The pick turns on one question: do you own the checkout, or are you sending traffic to someone else's?
Pick Hyros if you own a high-ticket, long-cycle funnel and need delayed, repeat and call-closed sales attributed back to your ads; pick Keitaro if you buy high-volume traffic to offers you may not own and want a flat-priced tracker you run yourself on your own server.
Quick answer
Keitaro is our top pick for most people. A proven self-hosted click tracker for media buyers: streams, filters, lander and offer rotation, split tests and server-to-server postbacks, on a flat EUR licence you run on your own VPS. It routes and optimizes paid traffic to offers you may not own, rather than attributing a long owned-funnel journey.
- Hyros. Best for High-ticket info, webinar and call funnels.
- Keitaro. Best for High-volume affiliate and media buyers who run their own tracker.

Hyros: pros and cons
What works
- Multi-touch attribution across a long journey (ad to opt-in to email to webinar to booked call), which last-click platforms miss.
- Sends offline and long-window sales back to Meta and Google so their algorithms optimize on real revenue.
- Call and high-ticket tracking is a first-class use case, not an afterthought, with named case studies from large info brands.
What to watch
- Hyros does not publish plan prices; cost is quoted after a demo and is aimed at higher-spend accounts, so it is opaque before a sales call.
- Operators repeatedly report it is involved to set up and overkill below roughly $50k/month in spend across multiple platforms.
- It will not fix low Event Match Quality or a weak offer; it makes the attribution clearer, not the funnel better.
Keitaro: pros and cons
What works
- The licence does not climb with your clicks. Individual plans run EUR 40 to 104 a month billed yearly, with no per-event or per-click cap, so a campaign that suddenly does volume never trips an overage fee the way a cloud tracker can.
- You own the data. Keitaro runs on your own VPS, so your click and conversion data lives on hardware you control, with retention you set rather than a cloud plan's limits.
- It is a deep media-buying tracker, not a light attribution layer: streams and filters on GEO, device, browser, operator and schedule, offer and lander rotation, A/B testing, server-to-server postbacks, conversion sync to Meta, TikTok and Google, more than 35 parameters and fast multi-level reports.
- It is established and well supported. Keitaro's own site cites more than 4,000 businesses, long-term reviews describe years of continuous use, and support is the single most repeated piece of praise, at 4.5 out of 5 on Trustpilot.
What to watch
- You run the server. The docs require a clean VPS on CentOS 9 or 10 Stream with KVM, 20 GB of SSD and 4 GB of RAM or more, and the domains, SSL, backups, updates and security are yours to keep up. That weighs most on a non-technical or low-volume buyer; a media buyer who already runs a VPS will find it a fair trade for owning the data.
- There is no free trial. You buy a licence to use it, so you cannot run a real campaign through it for free first, though a public live demo lets you click around the interface. That puts the burden on you to be sure before you pay.
- When the server or the support chain fails, it costs money. The sharpest reviews describe 502 errors on server-to-server conversion tracking and slow resolution. Those usually trace to an under-provisioned VPS rather than the tracker itself, but on a self-hosted tool part of your uptime is your own responsibility.
- It carries reputation baggage. Security researchers have documented Keitaro's traffic-distribution system being abused in malware and cloaking campaigns, so some strict ad networks view the toolset warily. That is about criminal misuse of a general routing tool rather than honest tracking, but it is a reason to keep your redirects clean and your use compliant.
The real differences
What each one actually is
Hyros is a revenue-attribution layer for a funnel you own. It plugs into a business you control, ties a customer's touches together across ads, email, webinars, calls and checkout, and sends the resulting sale back to Meta, Google and TikTok so their algorithms learn from real revenue rather than a last-click guess. Its own pitch names the hard cases it is built for: it says it specializes in tracking delayed purchases, high-ticket closes, reorders and subscription rebills back to the ads that created them.
Keitaro is a self-hosted click tracker for media buyers. You install it on your own Linux server, route your campaign links through it, and it records every click, its cost, the conversion and the revenue, then splits that traffic across landers and offers by rules you set. On top of tracking it does the buyer's daily job: streams and filters on GEO, device, browser, operator and schedule, offer and lander rotation, split tests, and server-to-server postbacks with conversion sync back to Meta, TikTok and Google. The vendor pitches it plainly, telling you to see exactly how your marketing efforts drive sales.
The split that decides it: do you own the checkout?
These two barely belong in the same comparison, and that is the useful part. The question that sorts them is whether you own the offer. Keitaro assumes you are buying traffic and sending it somewhere, often to an offer you do not control, and it is built to route that traffic, test it and read the conversion back through a postback. Hyros assumes you own the funnel and want to reconcile a long, messy buyer journey, then push the real sale back to the ad platform.
If you run affiliate or media-buying campaigns across native, push, pop and paid social to offers you do not own, Keitaro is the shape that fits. If you sell your own high-ticket program and most of the money lands weeks later or on a booked call, Hyros is the tool built for that exact gap. Its own numbers make the case for why the gap matters: it claims ad-platform tracking misses about 30 percent of your sales, and more than 90 percent of repeat purchases and delayed sales.
What Keitaro does that Hyros does not
Keitaro gives you a real traffic-distribution engine and the data behind it. You can rotate landers and offers, cap and auto-disable the underperformers, bind clicks to the best offer in real time, and read fast multi-level reports across more than 35 parameters. Because it is self-hosted, the click and conversion data sits on hardware you control, with retention you decide rather than a cloud plan's limits. And the price does not climb with your clicks: individual plans run a flat EUR 40 to 104 a month, with no per-event or per-click cap, so a campaign that suddenly does volume never trips an overage fee.
Hyros has none of that traffic-routing machinery, and it is not trying to. It is an attribution layer, not a place you build and split funnels. If routing, rotation and split-testing paid traffic is your daily work, that is Keitaro's job and not Hyros's.
What Hyros does that Keitaro cannot
Hyros is built to stitch a delayed, multi-touch, owned-funnel journey together and feed the resulting revenue back to the ad algorithms. That is the case where a click tracker runs out of road. Keitaro reads a conversion back through a postback at the moment it fires. It is not designed to reconcile a sale closed on a phone call three weeks after the click, or a rebill next month, and attribute it to the ad that started the journey. If that late, offline and repeat revenue is most of your money, the depth Hyros adds is the whole reason to pay for it. If it is not, you are buying a layer you will not use.
Setup and who runs it
This is the other hard divide. Keitaro is yours to run. Its docs want a clean VPS on CentOS 9 or 10 Stream with KVM, 20 GB of SSD and 4 GB of RAM or more, and the domains, SSL, backups, updates and security are your responsibility. A media buyer who already runs a server will find that a fair trade for owning the data. A non-technical operator will not. There is no free trial either, only a public live demo, so you buy the licence and then set it up.
Hyros is the opposite: cloud, and done for you. There is no server on your side, the team scopes and installs it, and there is no plan to self-serve. That convenience is real, and so is its cost, which is the next thing to weigh.
What each one costs
Hyros. No public pricing. You book a demo, the team scopes and installs it, and the quote is aimed at higher-spend accounts. There is no entry tier to test cheaply and no number to compare on a page, which is the trade for the done-for-you setup. Operators repeatedly describe it as overkill below roughly $50,000 a month in spend across several platforms.
Keitaro. A flat licence you can read before you buy. Individual plans are billed yearly at EUR 40 (Starter), EUR 72 (Advanced) and EUR 104 (Expert) a month, with Team and Enterprise higher, and Keitaro lists discounts for paying six or twelve months up front. There is no free trial, only a public live demo, and the Linux VPS you host it on is a separate ongoing cost on top of the licence.
So the honest comparison is not one price against another. Keitaro's total is a predictable licence plus a server bill you control. Hyros is a quote you cannot see until you talk to sales, set against the revenue it recovers. One is priced on your infrastructure, the other on your ad spend.
