Keitaro vs Binom vs Voluum: Which Tracker Wins for iGaming Affiliates?
24.06.2026 | 4 min
Choosing between Keitaro, Binom, and Voluum comes down to one question: how much control do you want over your infrastructure versus how quickly you want to launch campaigns?
Binom V2 processes up to 260 million clicks per day, with redirect speeds of 3–5 ms and report generation 30× faster than V1. Keitaro provides comparable self-hosted control for €49 per month, with more than 500 postback templates and 30+ traffic filters. Voluum starts at approximately €131 per month as a cloud-only solution with built-in automation and anti-fraud capabilities.
For affiliates working in the iGaming industry, S2S postback support matters more than any other feature because browser restrictions and ad blockers make cookie-based attribution increasingly unreliable.
What Makes a Tracker Right for iGaming Traffic
Tracking requirements in the iGaming industry differ significantly from traditional performance marketing. Conversions are typically multi-step events that move from click to registration, then to first deposit (FTD), and often to recurring deposits. Standard pixel tracking frequently loses attribution between registration and deposit when users leave and later return to complete the process.
According to IREV's 2026 research, Safari's Intelligent Tracking Prevention limits cookie lifespans to 7 days, while Safari accounts for roughly 20% of global traffic and around 30% of mobile traffic. Desktop ad blocker penetration also exceeds 40%, making browser-based tracking less dependable.
For this reason, S2S postbacks have become the standard. Instead of relying on browser cookies, the affiliate program platform sends conversion information directly to the tracker. This ensures attribution remains intact regardless of how long a user takes to make a deposit.
Key postback parameters typically include click_id, offer_id, conversion_status, and payout_value, while additional sub_id parameters allow detailed traffic-source analysis. A healthy setup should achieve a postback success rate above 98% and keep attribution variance between S2S and pixel tracking below 3%.
Postback Requirement
Any tracker used with an iGaming affiliate program should support the construction of custom postback URLs. Platforms such as Affilka rely on API-based S2S postback communication, making proper click_id passing essential for accurate attribution.
“Many affiliates blame an affiliate program when reg-to-FTD performance drops. In reality, attribution problems often originate from incorrect postback configuration. A tracker can report only the data it receives. If you do not configure Registration and FTD events correctly, your conversion analysis will become misleading.”

Binom: The Speed Case for High-Volume Affiliates
Binom V2 handles extremely large traffic volumes and was built specifically for affiliates operating at scale. Its architecture supports up to 3,000 clicks per second compared to 200 clicks per second in V1, representing a 15× increase in throughput.
The platform can process up to 260 million clicks per day and generate reports within seconds, even with up to 5 levels of report nesting. Binom replaced MySQL with ClickHouse, enabling report generation that is approximately 30× faster than in the previous version.
| Metric | Binom V1 | Binom V2 |
|---|---|---|
| Clicks per second | 200 CPS | 3,000 CPS |
| Daily capacity | Lower scale | 260M clicks/day |
| Database | MySQL | ClickHouse |
| Storage per 1M clicks | 3 GB | 1.5 GB |
| Report speed | Standard | 30× faster |
| Report nesting | Limited | Up to 5 levels |
Storage efficiency is another important advantage. Binom V2 requires approximately 1.5 GB per million clicks, down from 3 GB in V1, reducing VPS expenses for large-scale operations. Redirect speeds typically range between 3 and 5 milliseconds, compared with approximately 5–15 milliseconds for Keitaro and 10–30 milliseconds for cloud-based alternatives.
Built-in bot filtering, lander protection, cloaking support, and flexible permission management make it attractive for experienced media buyers. Pricing starts at approximately €43 per month for Binom Cloud and around €61 per month for the self-hosted license, excluding VPS costs. Self-hosted installations do not impose traffic limits or overage charges.
The primary limitation is infrastructure management. Teams must maintain servers themselves, and automation capabilities are less extensive than those available in Voluum. For affiliates processing millions of clicks through push, native, or similar high-volume traffic sources, however, Binom remains one of the most cost-efficient options available.
Keitaro: Flexible Routing at a Lower Entry Point
Keitaro focuses on routing flexibility, traffic distribution control, and funnel analysis rather than pure processing speed. Pricing begins at €49 per month for the Starter plan, followed by Advanced at €89, Expert at €129, Team at €249, and Enterprise at €499. All plans require a separate VPS, and a 14-day free trial is available.
Key capabilities include:
- More than 500 postback templates for traffic sources and affiliate programs.
- Over 30 traffic-filtering parameters, including device, OS, ISP, and custom conditions.
- Visitor Binding technology that returns users to the same destination throughout future visits.
- Flow Monitoring for funnel visualization and drop-off analysis.
- Local landing page hosting and real-time page editing.
- Keitaro 11 adds global search and custom metrics for more flexible reporting and analysis.
Visitor Binding is particularly valuable in iGaming funnels because users often register during one session and deposit later. By preserving routing consistency across visits, attribution remains more accurate throughout the funnel. Flow Monitoring helps affiliates identify exactly where users leave the conversion path, improving optimization decisions.
| Feature | Keitaro | Binom |
|---|---|---|
| Entry Price | €49 | €61 self-hosted |
| Postback Templates | 500+ | Extensive but fewer templates |
| Visitor Binding | Yes | No direct equivalent |
| Flow Monitoring | Yes | Limited |
| Redirect Speed | 5–15 ms | 3–5 ms |
| Multi-user Access | Expert Plan+ | Available |
| VPS Required | Yes | Yes |
Keitaro's primary limitation is that multi-user collaboration is available only on the Expert plan. Automation is also less advanced than Voluum's Automizer ecosystem. Nevertheless, affiliates seeking sophisticated routing and funnel control without paying cloud platform premiums often find Keitaro to be the best balance between functionality and cost.
Voluum: Cloud Automation Without Server Overhead
Voluum's value proposition centers on automation, cloud hosting, and operational simplicity. Affiliates do not need to maintain infrastructure, making deployment significantly easier. Pricing begins at approximately €131 per month for the Profit plan, increases to €193 for Scale, €527 for Startup, €879 for Agency, and €1,759 for Enterprise. Event limits apply across plans, and overage fees may increase costs as traffic volume grows.
| Plan | Approx. Monthly Price | Core Benefits |
|---|---|---|
| Profit | €131 | S2S tracking, automation, cloud hosting |
| Scale | €193 | Higher event limits |
| Startup | €527 | Expanded reporting and automation |
| Agency | €879 | Agency-level scaling |
| Enterprise | €1,759 | Maximum capacity and support |
Voluum includes Automizer, which allows direct API integrations with advertising platforms. Affiliates can use Automizer to automatically pause campaigns, sync costs directly from ad platforms, and exclude underperforming placements without manual intervention. Traffic Distribution AI dynamically reallocates traffic to higher-performing paths based on ROI, EPC, and conversion signals. The Anti-Fraud Kit functionality includes IP filtering, user-agent analysis, honeypot detection, and other fraud-prevention mechanisms. The platform also supports cookieless tracking, first-party cookies, Big Data Reports, and multiple conversion-event tracking for registration and FTD actions.
Campaign Limit Consideration
The entry-level Voluum Profit plan limits accounts to 20 campaigns. Keitaro Expert has no campaign cap, while Binom self-hosted deployments similarly avoid campaign restrictions. Affiliates running many simultaneous campaigns should account for this difference when comparing total costs.
Voluum is particularly attractive for affiliates operating across multiple paid channels who value automation more than infrastructure control.
Head-to-Head: Pricing, Speed, and iGaming Fit
| Feature | Keitaro | Binom | Voluum |
|---|---|---|---|
| Hosting | Self-hosted | Self-hosted / Cloud | Cloud |
| Entry Price | €49 | €43 Cloud / €61 Self-hosted | €131 |
| Redirect Speed | 5–15 ms | 3–5 ms | 10–30 ms |
| Event Limits | VPS dependent | Unlimited self-hosted | Plan based |
| Campaign Limits | No | No | 20 on entry plan |
| S2S Support | Yes | Yes | Yes |
| Anti-Fraud | Moderate | Moderate | Advanced |
| Automation | Moderate | Basic | Advanced |
| Multi-user Support | Expert+ | Yes | Yes |
| Best Traffic Type | Multi-step funnels | High-volume traffic | Multi-channel automation |
The decision framework is relatively straightforward:
- More than 50 million clicks per month → Binom V2 self-hosted.
- Multi-step funnels with returning users → Keitaro.
- Heavy automation requirements across multiple channels → Voluum.
- Collaborative teams without server management → Voluum Scale or Keitaro Expert.
Cost differences become substantial at scale. A Binom self-hosted setup handling 100 million clicks monthly may cost approximately €87–131 per month, including VPS expenses. Comparable cloud usage can push Voluum into plans costing approximately €527 per month or more, resulting in a monthly difference of roughly €396–€440.
For the iGaming industry specifically, all three trackers support S2S postbacks. Voluum provides the most automation. Keitaro excels at return-user attribution through Visitor Binding. Binom delivers the strongest combination of speed and cost efficiency for high traffic volumes.
How S2S Postbacks Connect Trackers to Affiliate Programs
Connecting a tracker to an affiliate program through S2S postbacks follows a predictable workflow:
- A user clicks an affiliate link.
- The tracker records the visit and generates a click_id.
- The user completes registration and eventually makes a first deposit.
- The affiliate program platform sends a postback containing click_id and conversion data.
- The tracker attributes the conversion to the original traffic source.
All three trackers use callback URLs with parameterized values. To
attribute conversions correctly, the affiliate platform needs to send
the correct click_id value to the tracker through the postback URL.
For affiliate programs using Affilka, setup typically requires the
tracker callback URL and a {click_id} macro substitution
within the postback template.
Affiliates should configure multi-event tracking from the beginning. Registration and FTD should be tracked as separate events, each with its own conversion value. This allows affiliates to analyze the progression from registration to FTD and identify quality differences across traffic sources. Always send a test postback before launching campaigns to verify that attribution works correctly. Attribution variance should remain below 3%. If it exceeds that threshold, the issue usually involves parameter passing rather than the affiliate program itself.
Common Mistake
Configuring postbacks only for FTD events prevents visibility into registration-to-FTD performance. Since reg-to-FTD is one of the most important quality indicators in iGaming traffic, losing this data severely limits optimization opportunities.
“FTD totals alone rarely tell the full story. Reg-to-FTD visibility reveals which traffic sources generate qualified users and which only generate registrations. Without separate event tracking, affiliates lose one of their most valuable optimization signals.”
