### Quick answer

Pick CPV Lab Pro if you want to prove a self-hosted tracker on a free trial before you pay, run your split tests and optimization from inside the tracker, and keep a managed cloud version in reserve for the day you would rather not run the server; pick Keitaro if your edge is deep traffic routing across 35+ parameters, you want CAPI and synced ad costs on every plan from a cheaper entry, and you will buy a license and run a Linux box to own your data outright.

CPV Lab Pro, from $57/mo.

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

If you are down to CPV Lab Pro and Keitaro, you have already settled the two biggest questions a tracker buyer faces. You want to self-host, so your click data lives on a server you control and nothing meters your events, and you want a flat license instead of a bill that climbs with your traffic. Both of these tools give you exactly that. Both are among the longer-running self-hosted trackers a media buyer runs, both stamp every click and follow it through your lander to an offer on any domain, both fire server-side postbacks to your networks, and both keep your data on hardware you own. So this is not a good-tracker-versus-bad-tracker choice. It is a choice between two capable self-hosted trackers built around different strengths.

The split is what each was built to do best, and one practical thing about trying them. CPV Lab Pro leads with testing: A/B and multivariate testing of landers and offers run from inside the tracker, and a 14-day free trial to prove the whole thing before you spend a cent. Keitaro leads with routing: a filtering engine across 35+ parameters that goes deeper than anything CPV Lab Pro offers, with CAPI and synced ad costs switched on from its cheapest plan, but no free trial to test it on first.

### The one thing that decides it: testing or routing

Answer this before you compare a single feature. Is your edge finding the winning combination, or expressing the exact rule that sends the right visitor to the right page? CPV Lab Pro's whole identity is track, test, optimize: it runs A/B and multivariate tests of your landers and offers from the tracker itself, records 30-plus data points on every click, and is built for the buyer whose job is to grind a campaign toward a better conversion rate. Keitaro's identity is routing: it splits visitors to different landers and offers across 35+ parameters, by geo, device, OS, browser, connection and source, and is built for the buyer whose campaigns live or die by the precision of that split. Both track well. The question is which of those two jobs is the one you do all day.

Then there is how you get in the door. CPV Lab Pro gives you a 14-day free trial, so you can stand it up on one real campaign and see it work before you pay. Keitaro has no free trial at all: you buy a license, with a public live demo and a refund policy as the only way to look before you leap. For a buyer who wants to prove a self-hosted tracker on their own traffic first, that difference alone can settle it, and it is the sharpest practical edge CPV Lab Pro holds here.

### CPV Lab Pro: test and optimize from the tracker, and a trial to prove it

CPV Lab Pro is the tracker for the buyer who treats optimization as the daily job. It runs on your own server, your data never leaves it, and it puts A/B and multivariate testing of landers and offers inside the tracker rather than making you bolt on a separate tool. It records 30-plus data points per click, fires cookieless server-to-server postbacks that keep working on iOS and in privacy browsers, and filters bots and proxies. Events are unlimited on every plan, with no click cap and no overage, so you can pour traffic at a winner without watching a meter. It has been shipping for roughly a decade, which is a long track record for a self-hosted tracker, and the 14-day free trial lets you confirm all of it on your own campaign before you commit. This site ranks it fifth among trackers, one place above Keitaro. The full [CPV Lab Pro review](/reviews/cpvlab-pro) covers how it holds up.

Its costs are honest and worth naming. Self-hosting is the real one: you supply and maintain a Linux VPS (PHP 8.1 to 8.4, MySQL or MariaDB, ionCube), and the cheap unlimited tracking is only as good as the machine under it. If server administration is not your thing, its managed cloud sibling CPV One exists for exactly that, an escape hatch Keitaro does not offer. The features most paid-media buyers come for, CAPI, automatic ad-spend cost sync and API access, start on the $97 Pro plan, not the $57 Starter, so budget the real entry price. And its independent proof is thin: Trustpilot sits at 3.8 from only 16 reviews, with most public praise living on affiliate forums like afflift rather than the big review sites. The trial is the due diligence the review count cannot give you.

### Keitaro: the deepest routing, CAPI on every plan, and no trial

Keitaro does the same core 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 the filtering engine. It splits visitors across 35+ parameters, by geo, device, OS, browser, connection and source, which is deeper than CPV Lab Pro's rule-based routing. 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, and it does all of that on every individual plan rather than gating it behind a higher tier the way CPV Lab Pro gates CAPI behind Pro. It also bundles a landing page editor, custom domains with SSL and bot filtering. For the buyer whose edge is routing logic and who wants the modern conveniences at a cheaper entry, Keitaro is the stronger pick, and on that ground we would take it over CPV Lab Pro without hesitation. The full [Keitaro review](/reviews/keitaro) goes through the routing depth in detail.

Its two real costs are the trial and support. There is no free trial: you buy a license, though a public live demo and a refund policy soften the commitment. And 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. 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. Like CPV Lab Pro it is self-hosted, so you rent and maintain a Linux VPS (CentOS 9 or 10 Stream, 4GB RAM minimum), but unlike CPV Lab Pro there is no cloud version to fall back on.

### Where the pricing diverges

Neither of these charges per event, which is the point of both, but they price on different axes and in different currencies. CPV Lab Pro is $57 a month for Starter and $97 for Pro, with one-time lifetime licenses that let you own the software outright, and the CAPI and cost sync most buyers need arrive on the $97 tier. Keitaro is a license ladder in euros: €40 a month for Individual Starter, €72 for Advanced and €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, and CAPI and cost sync on all of them. So which is the cheaper modern setup depends on what you need: Keitaro's €40 plan already carries CAPI, while CPV Lab Pro's does not arrive until $97\. On top of either sits the cost neither vendor puts on the invoice: the Linux server you rent, patch and keep online yourself.

Verify both on your own numbers. CPV Lab Pro's figures are public and flat, and the lifetime option changes the math if you plan to run it for years. Check which Keitaro tier actually carries the domains, seats and features you need, because the €40 entry is the floor, not the plan most volume buyers land on.

### A third path if you host the funnel yourself

Both of these tools measure traffic to pages and offers that live somewhere else. CPV Lab Pro and Keitaro both stamp a click and follow it to a lander and an offer you host on another platform, then catch the conversion as a postback. There is a different way to close the same gap, worth naming because it changes where the data lives. [ElasticFunnels](/reviews/elasticfunnels) is a funnel platform for teams running paid traffic that builds the pages and hosts the checkout itself, and keeps its ad-spend and conversion reporting on the same data layer as those 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 postback it has to catch, and it fires affiliate postbacks to your networks on purchase, refund, chargeback and renewal, the network-attribution job both trackers here do for click traffic. 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.

The honest limit that keeps it on its own line rather than in the table above: ElasticFunnels is newer than either tracker 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, where CPV Lab Pro has a decade of use behind it and Keitaro more than 4,000 businesses and a long, if mixed, support record you can read before you buy. Its reporting also covers the funnels it hosts, so a media buyer sending clicks to offers on other people's domains still needs a dedicated tracker like CPV Lab Pro or Keitaro for that traffic. And the whole reason you narrowed to these two is to self-host and own your server and data, while ElasticFunnels is hosted software you rent, so choosing it trades that ownership away. 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 optimize campaigns all day and want to try before you buy:** CPV Lab Pro. Built-in A/B and multivariate testing, 30-plus data points per click, unlimited events on your own server, and a 14-day free trial make it the right call for the buyer whose job is grinding a campaign toward a better conversion rate. Budget the server, and remember CAPI and cost sync start on the $97 Pro plan.

**Your edge is deep routing and you want CAPI on the cheapest plan:** Keitaro. Filtering across 35+ parameters, CAPI and cost sync on every tier from a €40 entry, and a bundled lander editor and bot filtering make it the better fit for a buyer whose campaigns turn on the precision of the split. Live with no free trial and business-hours support, and run the Linux server it needs.

**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 a tracker like CPV Lab Pro or Keitaro for any traffic that closes on domains you do not host.

CPV Lab Pro takes our default pick here, not because it out-routes Keitaro, but because the median reader who reaches this comparison wants to prove a self-hosted tracker on their own traffic before paying and to run their testing from the tracker itself, and CPV Lab Pro's free trial and built-in optimization answer both. On its own turf, a buyer whose campaigns live or die by the exact routing rule, Keitaro is plainly the stronger tool, and we would pick it every time for that operator. If you are still weighing self-hosted against cloud trackers, [ClickFlare vs CPV Lab Pro](/compare/clickflare-vs-cpvlab-pro) and [BeMob vs Keitaro](/compare/bemob-vs-keitaro) run that fork, [Binom vs Keitaro](/compare/binom-vs-keitaro) weighs Keitaro against another self-hosted rival, and you can see where both land in our [best ad tracker ranking](/best).

### CPV Lab Pro

##### What works

* Unlimited events, no click limits, no overage fees, on every plan. You can pour traffic at a winning campaign without watching a meter, which is the opposite of the event-metered pricing at Voluum and RedTrack where the bill climbs with volume.
* You own the data. It is self-hosted on your own Linux server, so your click logs and campaign data sit on hardware you control rather than a vendor's cloud. For many long-term affiliates that is the whole reason they run it.
* A full tracker, not a lite tool. Cookieless server-to-server postback tracking that keeps firing on iOS and in privacy browsers, 30-plus data points per click, bot and proxy filtering, A/B testing of landers and offers from inside the tracker, and multivariate testing on the top plan.
* Support is the part users praise most. Across the affiliate forum afflift and Trustpilot the repeated note is fast, knowledgeable help that walks you through postback and CAPI setup by name, and the vendor helps with the initial install at no cost.
* Predictable cost, and a lifetime option. Starter is $57/mo and Pro $97/mo, and one-time lifetime licences let you own the software outright instead of subscribing. No per-event bill to model.

##### What to watch

* Self-hosting is the real cost and the real risk. It runs on your own Linux VPS (PHP 8.1 to 8.4, MySQL or MariaDB, ionCube), a separate bill and your job to keep fast, patched and online. The cheap unlimited tracking is only as good as the machine under it. If server administration is not your thing, the cloud sibling CPV One or a managed tracker like RedTrack fits better.
* Expect a learning curve. Reviewers who like the tool still say the number of campaign types, settings and reports can overwhelm a beginner, so budget setup time.
* The features you probably came for start on Pro. CAPI, automatic ad-spend cost sync and API access are not on the $57 Starter plan, so the real entry price for a modern paid-media setup is $97/mo.
* Thin independent proof. Trustpilot sits at 3.8 from only 16 reviews, and most public praise lives on affiliate forums rather than the large review sites, a smaller footprint than Voluum or RedTrack. The 14-day trial is the due diligence the review count cannot give you.
* Overkill for a content-site affiliate. If all you need is which blog link got clicked, a link cloaker or your network's sub-ID report is simpler. This is far more tracker than that job wants.

### 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

CPV Lab Pro: from $57/mo. Four tiers, and every one includes unlimited campaigns and unlimited events, with no click limits and no overage fees. Starter is $57/mo month to month, or $48/mo billed annually ($577 a year). Pro is $97/mo, or $81/mo annually ($977). Expert is $187/mo, or $156/mo annually ($1,877). Agency is custom, quoted on a call. Lifetime licences are a one-time payment instead of a subscription: $1,157 Starter, $1,957 Pro, $3,757 Expert, and they cover CPV Lab v13 for life, not future major versions. CAPI, automatic ad-spend cost sync and API access begin on the Pro plan, not Starter. It is self-hosted, so a Linux VPS is a separate cost you pay your host. The trial runs 14 days with no card up front, backed by a 30-day money-back guarantee.

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

### CPV Lab Pro

CPV Lab Pro is real, and it is one of the longer-running trackers in the category: a self-hosted performance marketing tracker media buyers have run for a decade. If you buy paid traffic, want unlimited events with no click limits or overage fees, and are comfortable running your own server, you are unlikely to regret it. The catch is the deployment. You supply and maintain a VPS, the features you probably came for (CAPI and automatic cost sync) start on the $97 Pro plan, and its independent review footprint is thin, so lean on the 14-day trial to prove it on one real campaign before you commit.

### Frequently asked questions

CPV Lab Pro or Keitaro: which should I use? 

Pick CPV Lab Pro if you want to prove a self-hosted tracker on a free trial before you pay, run your split tests and optimization from inside the tracker, and keep a managed cloud version in reserve for the day you would rather not run the server; pick Keitaro if your edge is deep traffic routing across 35+ parameters, you want CAPI and synced ad costs on every plan from a cheaper entry, and you will buy a license and run a Linux box to own your data outright.

Which is cheaper, CPV Lab Pro or Keitaro? 

CPV Lab Pro starts at $57/mo and Keitaro at €40/mo, self-hosted license. Neither meters your clicks; both are flat self-hosted licenses. CPV Lab Pro's real entry is the $97 Pro plan once you need CAPI and cost sync, while Keitaro carries those on its €40 plan. Both also add a Linux VPS you rent and run yourself, so compare on your real setup, not the entry price.

Do CPV Lab Pro and Keitaro do the same job? 

Broadly yes, which is why the choice is close. Both are self-hosted trackers for paid-traffic buyers: both stamp a click, follow it through your lander to an offer on any domain, catch the conversion on the server, fire postbacks to your networks, and keep your data on a Linux box you run. The difference is emphasis. CPV Lab Pro is built around testing and optimization, with A/B and multivariate testing inside the tracker and a free trial to prove it. Keitaro is built around routing depth, puts CAPI and cost sync on every plan, and bundles a lander editor and bot filtering, but has no free trial.

Which is easier to try before I pay? 

CPV Lab Pro, clearly. It gives you a 14-day free trial, so you can stand it up on one real campaign and confirm the tracking and postbacks work before you spend anything. Keitaro has no free trial at all: you buy a license, with a public live demo and a refund policy as the only way to look before you commit. If proving a self-hosted tracker on your own traffic first matters to you, that gap is the sharpest practical reason to start with CPV Lab Pro.

Which has the deeper traffic routing? 

Keitaro. Its filtering engine splits visitors across 35+ parameters, by geo, device, OS, browser, connection and source, which is more granular than CPV Lab Pro's rule-based routing. If the exact routing rule is the feature you are choosing on, Keitaro is the stronger tool, and it carries CAPI and cost sync on every plan too. CPV Lab Pro answers back on testing: A/B and multivariate optimization run from inside the tracker, which is its own reason to pick it.
