Free affiliate tracking in iGaming is a narrower list than most roundups admit. The filter that eliminates most options fast: S2S postback support. Without it, you’re doing cookie-based tracking that breaks on mobile apps, ad blockers, and cross-device players. Here’s what actually survives that filter:
Affiliate tracking software exists on a spectrum. At one end: enterprise iGaming platforms charging €1,500+/month with native NGR dashboards, fraud detection, and built-in responsible gambling exclusion logic. At the other: open-source codebases that handle click tracking and conversion attribution but know nothing about game categories, RevShare models, or postback infrastructure.
Most operators searching for free affiliate tracking are somewhere in the middle — they need real tracking (not spreadsheets), they need postback support (not just cookies), and they’re not ready for or can’t justify enterprise pricing before their affiliate program generates meaningful revenue. This guide covers what’s actually available in that middle ground, with honest notes on where each option stops being sufficient for iGaming use cases.
Before the tool list, the most important technical constraint. iGaming affiliate tracking has a non-negotiable requirement that generic affiliate software often doesn’t meet: server-to-server (S2S) postback tracking.
Cookie-based tracking — the standard for e-commerce affiliate platforms — places a cookie in the user’s browser when they click an affiliate link, then reads that cookie when a conversion happens. In iGaming, this breaks in at least four ways: players use ad blockers that strip affiliate cookies before they’re set, iOS privacy changes (ITP) aggressively expire third-party cookies within 24 hours, mobile app players have no browser cookie context at all, and players who click on desktop and deposit on mobile create attribution gaps that cookie tracking cannot bridge.
S2S postback solves this by sending conversion data directly between your platform’s server and the tracking server when a qualifying event happens — no browser involved, no cookie dependency. When a player registers, your PAM fires a POST request to the tracking platform’s postback URL. When that player makes a first deposit, another postback fires. The attribution is server-confirmed, not browser-assumed.
For a deeper technical breakdown of how postback implementation works and when cookies are still the right choice, the postback URL implementation guide and the S2S vs cookie comparison are worth reading alongside this. The short version: any affiliate tracking tool for iGaming that doesn’t support S2S postback is a liability, not an asset.
iDevAffiliate isn’t open-source in the MIT license sense, but it’s self-hosted on your own server with a one-time license fee — no monthly SaaS charges, no per-affiliate pricing, no revenue share taken. For operators looking to escape recurring costs, that distinction matters. The license pays for itself in 1–2 months compared to any SaaS affiliate platform.
It supports S2S postback tracking, custom commission structures including percentage-based and flat CPA, multi-tier (sub-affiliate) commissions, an affiliate self-service portal, and payout management. For the iGaming-specific gap: there’s no native NGR calculation. You can configure custom commission tiers and percentage structures, but the platform doesn’t know what gross gaming revenue or bonus cost is — those calculations have to be done outside the system and imported as custom payout adjustments.
The postback implementation requires some configuration: you’ll set up postback URLs that your PAM fires on registration and deposit events, map those to iDevAffiliate’s conversion types, and verify attribution through the reporting dashboard. It’s not plug-and-play for iGaming, but it’s well-documented and achievable without specialist developers.
Peerclick offers a permanently free tier covering up to 100,000 tracked events per month — which for a small affiliate program (10–30 affiliates sending moderate traffic) is enough to run real tracking without any cost. It’s built for performance marketers, which means postback is a first-class feature rather than an add-on: S2S postback setup is standard, click-level attribution is granular, and the reporting interface is designed for traffic analysis rather than just conversion counting.
The iGaming fit is partial. Peerclick tracks clicks, conversions, and custom events — you define what a “conversion” means. For a simple CPA structure (pay per first deposit), this works well: configure your postback to fire on first deposit, set your CPA value, track affiliate performance. For RevShare models that calculate commission on ongoing player revenue, Peerclick has no native concept of recurring player value — you’d need external calculation and payout management.
The free tier is genuinely free, not a trial — you stay on it until you exceed 100k monthly events. For a bootstrapped iGaming affiliate program in its first 6 months, that limit is probably sufficient.
Voluum itself isn’t free — it’s a paid performance marketing platform. What’s relevant here is the ecosystem of open-source performance trackers built to similar architectural standards: RedTrack alternatives on GitHub, self-hosted click trackers with postback infrastructure, and modular tracking systems that performance marketers build and share. Tools like Bemob’s open components, AdsBridge-style redirect trackers, and self-hosted LAMP stack trackers with postback support exist in this category.
For a development team comfortable with server configuration, building a lightweight self-hosted tracker on open-source components is a real option. The core components — click redirect handler, postback endpoint, conversion attribution logic, and reporting database — are achievable in a few hundred lines of well-structured code. The result is a tracker you own completely, with no event limits, no recurring fees, and no data leaving your infrastructure.
The investment is significant: you need a developer who understands server-side tracking, you need to handle your own uptime and maintenance, and any reporting beyond basic conversion counts requires custom development. But for operators who already have in-house technical capability and want permanent zero-cost tracking infrastructure, this is the highest-control option available.
Binom is a self-hosted click tracker built for performance marketers — which means postback tracking, multi-offer rotation, granular click-level reporting, and a back-end that handles high traffic volumes without the latency issues that plague cloud-based trackers. At $49/month after the trial, it’s one of the lowest-cost options with real postback infrastructure.
The 14-day trial is full-featured — you install it on your own server (it needs a VPS, which is an additional cost consideration) and run actual tracking against your affiliate program. That’s enough time to validate the postback integration with your PAM, test conversion attribution accuracy, and evaluate the reporting interface against your operational needs.
For iGaming: same gap as the other non-native tools. Binom tracks clicks and conversion events as you define them. It does not understand RevShare models, NGR calculations, or iGaming-specific fraud patterns. CPA structures work cleanly; RevShare requires external calculation.
Keitaro is Binom’s closest competitor in the self-hosted performance tracker space. It covers more landing page and traffic distribution features than Binom (more relevant for media buyers than iGaming operators), but its postback infrastructure and conversion tracking are equally solid. The trial period gives you two weeks on full functionality — enough for proper integration testing.
Where Keitaro occasionally gets cited for iGaming use cases is in affiliate fraud detection: it has more built-in traffic quality analysis than Binom, including bot detection and suspicious click pattern flagging. For operators whose affiliate traffic includes media buyers and paid traffic sources (where fraud is more common than with SEO content affiliates), that built-in analysis has real operational value.
If your platform already has an API and your team has back-end development experience, building a lightweight affiliate tracking layer in-house is simpler than most operators expect — and considerably simpler than building a full sportsbook or casino platform. The core components of a basic affiliate tracking system are: a click handler that generates unique click IDs and stores them with affiliate reference data, postback endpoints that receive conversion events from your PAM and match them to stored click IDs, a commission calculation layer that applies your deal terms, and a reporting interface for affiliates to check their stats.
The affiliate portal — the dashboard your affiliates log into to see their clicks, registrations, and earnings — is usually the most time-consuming piece. Consider using a simple static reporting approach (automated email reports or a read-only Google Data Studio dashboard) for the first affiliates while you validate that the tracking itself is accurate, then build the portal once you’ve confirmed the underlying attribution is working.
For RevShare models specifically, in-house tracking has an advantage over generic third-party trackers: your database already has the GGR, bonus, and revenue data needed to calculate NGR-based commissions accurately. A custom system can calculate and report RevShare natively in a way no generic tracker can match.

Every tool on this list has the same limitation for RevShare affiliate deals: none of them calculate NGR natively. This isn’t a feature oversight — it’s a fundamental data access problem. NGR calculation requires your platform’s gross gaming revenue figures, bonus cost data, chargeback records, and payment processing fees. That data lives in your PAM or financial reporting system, not in a third-party tracker.
Generic trackers can receive a postback that says “this affiliate’s player generated a conversion.” They cannot receive a postback that says “this affiliate’s player generated €340 in GGR this month, of which €45 was bonus cost, €12 was a chargeback, and €8 was payment fees, giving you €275 NGR at your 30% RevShare deal, meaning a €82.50 commission this month.”
Purpose-built iGaming affiliate platforms — Scaleo, MyAffiliates, Affilka, and others — handle this because they integrate directly with your PAM via API and receive the full financial event stream. That integration is what justifies their pricing, and it’s the feature that determines when operators outgrow free tracking tools.
For operators currently running RevShare deals on free or generic tracking: you’re almost certainly doing monthly reconciliation in a spreadsheet. That’s manageable at 5–10 affiliates. At 20–30 affiliates with individual deal terms, it becomes a material operational cost and an error risk. That’s the inflection point where iGaming-native affiliate software earns its cost back in time saved and disputes avoided.
Regardless of which tool you choose, the postback integration with your platform needs to be validated before you tell affiliates their traffic is being tracked. A broken postback that silently fails to record conversions is the fastest way to destroy affiliate relationships — affiliates who don’t get credited for traffic they sent will leave, and they’ll tell others.
The validation checklist before going live:
Running these tests with a real affiliate before going live is better than running them in isolation — you want to confirm that the click ID generated when an affiliate clicks their own link resolves correctly through your entire tracking chain, not just in a synthetic test environment.
Three signals tell you the free tracking tier is costing more than it saves:
You’re doing manual RevShare reconciliation monthly. If your finance or affiliate team spends more than 2–3 hours per month calculating RevShare payouts in a spreadsheet, the time cost of that manual process probably exceeds what a purpose-built iGaming affiliate platform would charge. Calculate the hourly cost of the people doing that reconciliation and compare it to platform pricing.
Affiliates are raising attribution disputes. When affiliates start questioning whether their traffic is being tracked accurately — because postback fires are inconsistent, or reporting latency is causing confusion — the relationship cost of those disputes is real. Purpose-built platforms have built-in audit trails and affiliate-facing reporting that reduce disputes significantly.
You’re managing more than 20 active affiliates with individual deal terms. The complexity of managing different commission structures, different deal terms, and different payout schedules across 20+ affiliates in a generic tracker becomes an operational problem. Purpose-built platforms automate deal management in ways that generic trackers can’t. The iGaming affiliate software comparison and vendor breakdown cover what’s available when you reach that point.
Affiliate tracking software records which affiliate sent each player to your platform, attributes conversions (registrations, deposits) to the correct affiliate, calculates commissions based on your deal terms, and provides reporting for both the operator and the affiliate. iGaming operators need it because without accurate tracking, you cannot pay affiliates correctly, cannot measure which affiliate traffic converts to depositing players, and cannot detect fraud or poor-quality traffic before it costs you in bonus payouts. Without tracking, an affiliate program is essentially unmanageable beyond a handful of manually reconciled partners.
Open-source or self-hosted affiliate tracking software can handle the core tracking functions for iGaming — click attribution, S2S postback conversion recording, and CPA commission calculation. What it cannot do natively is calculate NGR-based RevShare commissions, detect iGaming-specific fraud patterns, or integrate with responsible gambling tooling to exclude self-excluded players from affiliate tracking. For simple CPA deal structures with a small number of affiliates, open-source or low-cost self-hosted trackers are adequate. For RevShare models or programs with more than 20 active affiliates, purpose-built iGaming affiliate platforms handle the complexity more reliably.
When a player clicks an affiliate link, the tracking system generates a unique click ID and stores it with the affiliate reference. This click ID is passed through to your platform’s registration page as a URL parameter. When the player registers, your platform (PAM) stores the click ID against the player record and fires a server-to-server HTTP request to the tracker’s postback URL, passing the click ID and conversion details. The tracker matches the postback to the original click using the click ID and credits the affiliate. No browser cookie is involved — the attribution survives ad blockers, device changes, and browser privacy settings because it happens entirely between servers.
Not natively. RevShare calculation requires ongoing access to your platform’s gross gaming revenue, bonus cost, chargeback, and payment fee data to calculate NGR and apply the agreed commission percentage. Generic and open-source trackers can record conversion events but don’t have access to this ongoing financial data stream. The workaround is external reconciliation: export your NGR data monthly, calculate RevShare payouts in a spreadsheet, and upload the results as manual payout adjustments in your tracker. This works for small programs but becomes error-prone and time-consuming above 15–20 active affiliates.
For permanent low-cost tracking, iDevAffiliate at $199 one-time with your own hosting ($5–10/month) is the lowest total cost of ownership for a self-hosted option with genuine postback support. Peerclick’s free tier (up to 100,000 events/month) has zero cost if you stay within the event limit. For operators with development capacity, a custom postback endpoint built in-house has zero recurring cost and the most flexibility. None of these options handle RevShare natively — CPA structures only without external reconciliation.
Affiliate tracking software handles the technical layer — recording clicks, attributing conversions via postback, and calculating commissions. An affiliate management platform covers the full operational layer: recruiting affiliates, managing deal terms and contracts, running the affiliate-facing portal and reporting dashboard, processing payouts, detecting fraud, and handling compliance requirements. Most free and open-source tools are trackers, not full management platforms. Purpose-built iGaming affiliate platforms like Scaleo, MyAffiliates, and Affilka are full management platforms that include tracking as one component of a broader system.
