### Quick answer

Pick ClickFlare if you want full cloud tracking with CAPI and synced ad costs on every plan at a flat price, would rather run nothing than maintain a server, and you accept its thin outside proof and test on your own traffic first; pick Keitaro if you buy paid traffic at real volume, want the deepest routing rules and to own your data outright on a Linux box you run, and would rather pay a flat license than meter every event in someone else's cloud.

ClickFlare, from $69/mo, billed yearly.

Keitaro, from €40/mo, self-hosted license.

If you are down to ClickFlare and Keitaro, you have narrowed to two serious trackers that do the same job for a paid-traffic buyer: stamp every click, follow it through your landing page to an offer on any domain, catch the conversion on the server, and report which source, lander and offer made money. Both fire server-to-server postbacks, both send conversions back to Meta, Google and TikTok through the ad platforms' own APIs, and both pull your ad spend in to compute real ROI. So this is not a question of one tool doing more than the other at the core. It is a question of how you want to run tracking, and at what scale.

The split is hosting and ownership. ClickFlare is a managed cloud tracker you log into, priced by events, with nothing to install and the vendor keeping it online. Keitaro is a self-hosted tracker and traffic router you install on your own Linux server, with a flat license, no event cap and the deepest routing rules of the two. One asks nothing of you but a login and a bill that grows with your volume. The other asks you to run a server, and in return never meters a single click and keeps all your data on hardware you control.

### The one question that decides it: will you run a server?

Answer this before you weigh a single feature. Do you want tracking that is simply there when you log in, and are you happy for your data to sit in a vendor's cloud and your bill to track your events? Or do you push real volume, want to own your data outright, and refuse to pay a tax on every click even if that means running the box yourself? The first buyer belongs on ClickFlare. The second belongs on Keitaro. Almost everything else follows from that one answer.

ClickFlare removes the operations entirely. There is no VPS to rent, patch or scale, no DNS or PHP tuning, and no overnight outage that is yours to fix. It has run since January 2021 with a 99.99% uptime record and more than 3,500 buyers, and it puts CAPI and automatic cost sync on every tier, including the $69 Starter, so you are not upgrading to reach the features a media buyer uses daily. The trade is that your events are metered, so the bill climbs as you scale, and your click data lives in ClickFlare's cloud rather than on your own infrastructure.

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. It splits visitors to different landers and offers across 35+ parameters, by geo, device, OS, browser, connection and source, which is deeper than ClickFlare's standard routing. The license is flat with no event cap, and your data lives on a machine you control. The cost is operational: you rent a clean Linux VPS, patch it, and own uptime and scaling yourself.

### ClickFlare: managed cloud, features on every plan

ClickFlare is the tracker for the buyer who wants full tracking without running anything. It captures conversions server-side with both redirect and direct tracking, so a blocked pixel or an iOS restriction does not silently drop the form fill or the sale, and it feeds those conversions back to Meta, Google, TikTok, Snapchat and Reddit while pulling your ad spend in to compute ROI by source, lander and offer. An AI Copilot, traffic-routing tools and a tag manager come with it. The point buyers make most is that cost sync and CAPI are on every tier, so you never upgrade to reach them, at a flat price the vendor says has not risen since 2021\. The [ClickFlare review](/reviews/clickflare) covers how well that holds up.

State the limits flat. Independent proof is thin: a couple of dozen Trustpilot reviews, all five-star, and little organic discussion next to the older incumbents, with Trustpilot itself flagging the sample may not be representative. Cost data also lags on the lower tiers, refreshing hourly on Starter and Pro, so an hour-old ROAS can mislead on a fast-moving campaign. And everything counts as an event, so high-volume pop or push traffic burns a tier faster than the plan names suggest. The counter to all of it is the 14-day trial with no card: prove the tracking on your own traffic and trust that over any score. It sits fourth in [our ad tracker ranking](/best), two places above Keitaro.

### Keitaro: routing depth and a license you own

Keitaro puts its weight on routing and ownership. Beyond the CAPI, cost sync and postbacks it shares with ClickFlare, it splits traffic across 35+ parameters for granular routing, and 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. There is no click cap and no per-event meter, the license is flat, and your data lives on hardware you control. 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 ClickFlare every time. The [Keitaro review](/reviews/keitaro) goes through the routing depth in detail.

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, which for a media buyer means daily lost optimization while it is open. Live chat also runs roughly 06:00 to 16:00 GMT on weekdays, so a launch that breaks overnight in your timezone waits for the next window.

### The trade-off, plainly

This is not one tool beating the other on the tracking itself. Both capture conversions server-side, feed the ad platforms and sync your costs. It is managed convenience against ownership and depth. ClickFlare gives you a login, features on every plan and nothing to run, at the cost of event-based pricing and data that lives in its cloud. 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 buyer who never wanted to touch a server onto Keitaro and they inherit a VPS and a patching schedule to run tracking ClickFlare would have hosted for them. Point millions of clicks at ClickFlare and the event meter starts 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, because the feature lists overlap heavily. If you want tracking that is there when you log in and never want to own a server, the managed 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 ClickFlare's event meter 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. ClickFlare prices by events, where a visit, a click, a conversion and a postback each count: $69 a month billed yearly for a million events, $169 for five million and $329 for twenty million, with overage billed per thousand rather than a hard stop, and the vendor says the price has not risen since 2021\. Keitaro is a tiered license instead: €40 a month for Individual Starter, €72 for Advanced and €104 for Expert, then €200 and €400 for its Business 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 your 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 ClickFlare nor Keitaro builds or hosts the funnel it measures. Both follow clicks to pages and offers that live somewhere else, then feed a signal back after the fact. [ElasticFunnels](/reviews/elasticfunnels) owns that middle instead. It is a funnel platform for teams running paid traffic that builds the landing pages, hosts the checkout with order bumps and upsells, 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 rather than a click it has to match later, and it fires affiliate postbacks on purchase, refund, chargeback and renewal from that same record. 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 and nothing on sales you run through outside networks.

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

### Which one for you

**You want full tracking without running anything:** ClickFlare. Managed cloud, CAPI and cost sync on every plan at a flat $69, and a 99.99% uptime record cover the day-to-day of a media buyer with nothing to maintain. Accept the thin outside proof, estimate your event count before you pick a tier, and test on your own traffic in the no-card trial first.

**You buy paid traffic at volume and want to own the stack:** Keitaro. Routing across 35+ parameters, 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 pages and checkout end to end:** look at ElasticFunnels alongside them, with the newness and the rented-not-owned caveats above in mind, and keep ClickFlare or Keitaro for any click traffic that lands on domains it does not host.

ClickFlare takes our default pick here, not because it out-tracks Keitaro, but because most readers weighing these two want their tracking managed rather than self-run, and a buyer choosing a cloud tracker over 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 the deepest routing and owned data, Keitaro is plainly the stronger tool, and we would pick it every time for that operator. If you want to weigh ClickFlare against a self-hosted tracker built the same way, [Binom vs ClickFlare](/compare/binom-vs-clickflare) runs that fork, and [BeMob vs Keitaro](/compare/bemob-vs-keitaro) and [Binom vs Keitaro](/compare/binom-vs-keitaro) weigh Keitaro against its other cloud and self-hosted rivals. You can also see where both land in our [best ad tracker ranking](/best).

### ClickFlare

##### What works

* Cost sync and CAPI are on every tier, including the $69 Starter. You pull your spend in, compute ROI and send conversions to Meta, Google and TikTok server-side, without a paid upgrade and without handing over a cut of your budget.
* Flat pricing that undercuts Voluum on the same event model. The vendor says the price has not risen since it launched in 2021, and there is no percentage of your budget layered on top.
* Server-side capture with both redirect and direct tracking, so a blocked pixel or an iOS restriction does not silently drop the form fill or the sale.
* Free done-for-you migration and fast human support are the two things public reviewers single out most, alongside a setup that is smoother than trackers usually are.
* A real 14-day trial with no card, plus a 99.99% uptime record since January 2021, so you can prove the tracking on your own traffic before you pay.

##### What to watch

* Thin independent proof. A couple of dozen Trustpilot reviews, all five-star, and little organic Reddit discussion. Trustpilot itself flags that the sample may not be representative, so the trial is your real due diligence, not the scores.
* Everything counts as an event. Every visit, click, conversion and postback draws down one limit, so high-volume pop or push traffic burns the cap faster than the plan names suggest. Estimate your real event count before you pick a tier.
* Spend data lags on the lower tiers. Starter and Pro refresh hourly and Master every 30 minutes, with near-real-time updates a paid add-on. On fast-moving campaigns an hour-old ROAS can mislead you.
* Less battle-tested at extreme scale than Voluum. For the heaviest automation rules and deepest anti-fraud, the older incumbents still have the longer public track record.
* Billing is charged in advance and is generally non-refundable, and you cancel inside the account rather than by asking support. Export your data before you leave.

### Keitaro

##### What works

* Self-hosted, so your click data lives on hardware you control and nothing meters your events. The license is flat, not a bill that climbs with clicks, which is the whole reason high-volume pop, push and native buyers pick it over event-priced cloud trackers like Voluum and RedTrack.
* Deep traffic routing and filtering. It splits visitors to different landing pages and offers by GEO, device, OS, browser, connection and source ID, across 35+ tracking parameters, so one tool handles the tracker, the routing and lander rotation.
* Server-side postbacks and conversion sync on every individual plan. It fires S2S postbacks and sends conversions back to Meta, Google and TikTok through their APIs, and pulls ad spend in so reports show real cost and ROI, not clicks alone.
* Support and price are what long-term users praise most. Across Trustpilot the repeated note from people running it for one to several years is fast, knowledgeable help and a low price relative to cloud trackers.
* A built-in landing page editor, custom domains with SSL, and bot filtering, so there are fewer separate tools sitting between your tracker, your lander and your offer.

##### What to watch

* Self-hosted only, and that is the real cost and the real risk. You rent a clean Linux VPS (CentOS 9 or 10 Stream, 4GB RAM minimum), and keeping it fast, patched and online is your job, not the vendor's. There is no cloud version, so if server operations are not your thing, a managed tracker like RedTrack or Voluum fits better.
* No free trial. To try it properly you buy a license, though there is a public live demo and a refund policy. That is more commitment up front than the card-free trials most cloud trackers offer.
* When tracking breaks, resolution can be slow. 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.
* A real learning curve. DNS, SSL, Cloudflare settings, server load, PHP-FPM tuning and postback debugging are all on you, and reviewers who like the tool still say the number of settings and reports can overwhelm a beginner.
* Live chat runs business hours, not around the clock. Support is online roughly 06:00 to 16:00 GMT on weekdays, so a launch that breaks overnight in your timezone waits until the next window.

### Pricing

ClickFlare: from $69/mo, billed yearly. Priced flat by monthly events, not a percentage of ad spend. Events count visits, clicks, conversions and postbacks together. Starter is $69/mo billed yearly ($89 monthly) for 1M events, Pro $169/mo yearly ($219 monthly) for 5M, Master $329/mo yearly ($429 monthly) for 20M, then Agency $559, Enterprise $959 and Corporate $1,759 (yearly). Overage runs $0.04 per 1,000 events on Starter down to $0.015 on Corporate and never stops your tracking. CAPI, the AI Copilot, the tag manager and synced ad costs come standard from the Starter tier up. 14-day free trial, no card, plus free done-for-you migration from another tracker.

Keitaro: from €40/mo, self-hosted license. Self-hosted only, so on top of the license you rent and maintain your own VPS. Individual plans, billed annually, are Starter €40/mo (1 user, 1 domain), Advanced €72/mo (1 user, 100 domains) and Expert €104/mo (up to 5 users, 500 domains); business plans are Team €200/mo (up to 50 users) and Enterprise €400/mo (unlimited users and domains, branding). It has no free trial: you buy a license, though a public live demo and a refund policy are offered, and 6- or 12-month terms discount 10% and 20%.

Our pick

### ClickFlare

ClickFlare is real. It is an established cloud tracker, running since 2021 and used by 3,500-plus media buyers, that does what Voluum and RedTrack do: server-side capture, CAPI to Meta, Google and TikTok, and spend pulled in for you to compute ROI, all on one flat price. You are unlikely to regret it if you run the 14-day no-card trial against your ad platform's own numbers first. The one real caveat is thin public proof, so trust the trial, not the review scores.

### Frequently asked questions

ClickFlare or Keitaro: which should I use? 

Pick ClickFlare if you want full cloud tracking with CAPI and synced ad costs on every plan at a flat price, would rather run nothing than maintain a server, and you accept its thin outside proof and test on your own traffic first; pick Keitaro if you buy paid traffic at real volume, want the deepest routing rules and to own your data outright on a Linux box you run, and would rather pay a flat license than meter every event in someone else's cloud.

Which is cheaper, ClickFlare or Keitaro? 

ClickFlare starts at $69/mo, billed yearly and Keitaro at €40/mo, self-hosted license. But they do not scale the same way: ClickFlare's bill climbs with your events, while Keitaro's license is flat with no event cap and adds a VPS you rent and run yourself. Count your real volume and your server cost before you choose.

Do ClickFlare and Keitaro do the same job? 

Largely yes, which is why the choice is about how you run it rather than what it does. Both are trackers for paid-traffic buyers: they stamp a click, follow it to your lander and offer on any domain, catch the conversion on the server, and report which source and offer made money. Both also fire server-to-server postbacks, feed the ad platforms through their conversion APIs, and sync your ad cost for real ROI. The difference is hosting and scale. ClickFlare is managed cloud priced by events; Keitaro is self-hosted with a flat license, no event cap and deeper routing. Pick by your volume and whether you will run a server.

Can I run Keitaro without managing a server? 

No. Keitaro is self-hosted only, with no cloud version, so running it means renting a Linux VPS and keeping it patched, fast and online yourself. There is a public live demo you can click through, but real traffic means installing and maintaining your own server. If you want full tracking without operations work, that is exactly what ClickFlare's managed cloud gives you, and it is the main reason a buyer who does not want to run a box picks ClickFlare here.

Which has the deeper traffic routing, ClickFlare or Keitaro? 

Keitaro. It splits visitors across 35+ parameters, by geo, device, OS, browser, connection and source, which is deeper and more granular than ClickFlare's standard routing rules. Both feed the ad platforms through CAPI and sync your cost, so routing depth is where the two genuinely part: if your edge is complex rule-based routing across many landers and offers, Keitaro is built for it, while ClickFlare covers the routing most buyers actually use without a server to run.
