Voluum vs Keitaro
By Marcus Flynn, tracking and attribution editor. Updated 24 September 2026.
You are down to two trackers built for the same operator: the media buyer sending paid clicks to offers they do not own, across native, push, pop and search. Voluum and Keitaro both route clicks, rotate offers and landers, and read conversions back through server-to-server postbacks. The difference is not the job. It is who runs the thing. Voluum is a cloud account you log into and someone else keeps running. Keitaro is software you install on your own server, on a licence that costs the same whether you push a thousand clicks or a billion. The pick turns on that one fact more than on any feature either one lists.
Pick Voluum if you want a managed cloud tracker with click routing and an anti-fraud kit built in and no server to run; pick Keitaro if you push very high click volume, can run your own server, and want a flat licence that never climbs with your traffic and keeps your data on your own box.
Quick answer
Voluum is our top pick for most people. The veteran affiliate and media-buying tracker: click routing, S2S postbacks, cookieless tracking and a strong anti-fraud kit, on a managed cloud account with no server to run. Priced on events, for buyers who live in native, pop and push.
- Voluum. Best for Affiliate and native/pop/push buyers who want nothing to host. From $119/mo.
- Keitaro. Best for High-volume affiliate and media buyers who run their own tracker.
Side by side
| Tool | Core job | Hosting | Pricing | Fraud tools | Data ownership | From |
|---|---|---|---|---|---|---|
| Voluum | Cloud media-buying tracker | Cloud, managed | Event-priced, from $119/mo | Anti-Fraud Kit built in | On Voluum's cloud | $119/mo |
| Keitaro | Self-hosted tracker / TDS | Self-hosted VPS | Flat EUR licence + server | Bot filtering built in | On your own server | Not listed |
Voluum: pros and cons
What works
- Deep click-routing and traffic-distribution rules built for zone, publisher, GEO, device and sub-ID optimization.
- Cookieless tracking and S2S postbacks that hold up on redirect-style affiliate flows where browser pixels fail.
- The Anti-Fraud Kit flags suspicious traffic automatically, which matters most on native and pop inventory.
- Cloud-hosted with automatic migration from an old tracker, so there is no server to run.
What to watch
- The automation layer, Automizer, is billed separately from $375/mo on top of the plan, so real automation costs stack fast.
- Full server-side CAPI depth and higher event ceilings sit on the expensive upper tiers ($539 to $1,599/mo).
- It is built around click routing and offer/lander optimization more than ecommerce customer-journey attribution.
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: 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.
- 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, usually tracing 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
Voluum is a cloud-hosted campaign tracker. You route an ad click through it, it records the visit on its own servers, passes an ID to the offer, and reads the conversion back through a server-to-server postback. Around that sit the tools a media buyer lives in: deep click-routing rules by zone, publisher, geo, device and sub-ID, offer and lander rotation, cookieless tracking that survives browser privacy rules, and a built-in Anti-Fraud Kit. It is cloud, so there is no server to run, and it migrates automatically from an older tracker. It is the veteran of the native, pop and push lane, with the largest user base of any tool on this site.
Keitaro is the same category delivered the opposite way. It is a self-hosted tracker from Apliteni that you install on your own Linux server. You route your campaign links through it, and on top of tracking clicks, cost, conversions and ROI it does the media buyer's daily job: it distributes traffic across landing pages and offers by rules you set, on geo, device, browser, operator and schedule, with offer and lander rotation, A/B tests and server-to-server postbacks. The thing you buy is a licence to run software yourself, not an account someone else runs for you. That difference decides more of this comparison than any single feature.
The split that decides it: cloud account or your own server
These two do the same core job, on the same kind of traffic, for the same operator: the media buyer pushing paid clicks to offers they do not own. The question that sorts them is whether you want a server in your life. Voluum is a managed account: nothing to host, you sign up and start, and the vendor keeps it running. Keitaro is software you own and operate, living on a VPS you rent and maintain, and everything that server needs is your responsibility.
That one decision drags the rest along with it. Ownership of your data, the shape of the bill, how much technical work you take on, and how the cost behaves as your click volume grows all follow from it. Get the server question right and the rest of the comparison mostly answers itself. It is the same trade you weigh in Voluum against the self-hosted Binom, with Keitaro's flat EUR licence in Binom's place.
Anti-fraud, cloaking and offers you do not own
Both carry the affiliate-buyer toolkit, and they bundle it in ways that matter on native and pop inventory where junk clicks are common. Voluum builds its Anti-Fraud Kit into the product, flagging suspicious traffic automatically, so the fraud screen is part of what you pay for. Keitaro ships bot filtering and a traffic-distribution system of its own, with cloaking built in, and syncs conversions back to Meta, TikTok and Google through server-to-server postbacks across more than 35 parameters. Its routing engine is deep enough that security researchers have documented it being abused in cloaking and malware campaigns, which is criminal misuse of a general tool rather than a fault in honest tracking, but it is why some strict networks eye the toolset warily and why you keep your redirects clean.
Neither is built to feed owned, multi-touch store revenue back to the ad platforms the way a paid-social tool is. Voluum tracks offers you own with a conversion pixel and puts fuller CAPI depth on its upper tiers; Keitaro's centre of gravity is routing rather than platform-side attribution polish. If your spend is mostly Meta or TikTok on a store you own, look at RedTrack or the wider tracking roundup instead. Both of these are aimed at the click, on offers you do not own.
Who each one is for
Voluum fits the media buyer who wants a tracker that just runs. Native, push, pop and search, several traffic sources at once, offers and landers rotated and tested on the click, and an anti-fraud kit and a big community to lean on when something breaks: that is the shape a Voluum account is built around, and it is why it stays a default in the affiliate lane despite costing more than the self-hosted options. Its price is the trade for the managed service.
Keitaro fits the same buyer at higher volume who is comfortable running infrastructure. A click count high enough that event pricing gets expensive, the willingness to own a server, and a preference for keeping your click and conversion data on your own box with retention you set: that is where a flat licence pays off, and support is the single most praised thing about it when something does break. Below that volume it is more machinery than the job needs, and if a self-hosted tracker is the direction you are leaning, the alternatives to Keitaro are worth a look first. For anyone who does not want to run a server, that alone rules it out.
One caveat applies to both. 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.
What each one costs
Voluum publishes self-serve, tiered pricing. Annual plans run from about $119 a month at the entry tier up to $1,599 a month for Enterprise, and the Automizer automation layer is billed separately from $375 a month on top of the plan. Event ceilings and full CAPI depth climb with the tier, so the real monthly cost depends on the plan plus whichever add-ons you switch on, but you can see every number before you buy, and there is no server in the bill.
Keitaro publishes a flat licence that ignores your click count. Individual plans are billed yearly at EUR 40 (Starter), EUR 72 (Advanced) and EUR 104 (Expert) a month, with Team and Enterprise higher. 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.
The cost decision follows the server decision. At a low or moderate event count Voluum is both cheaper and less work, because there is no server in the bill. Push enough clicks that per-event pricing turns into a four-figure monthly line, and Keitaro's flat licence plus the cost of running a box is the cheaper of the two, provided you can run the box.
