Simple Kuma review
A free open-source tracker for campaign performance, without affiliate portals or commission reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Simple Kuma is an open-source, self-hosted affiliate and media-buying tracker for developers and marketers who need control over campaign, offer, landing-page, traffic-source, click, and conversion data. Its core workflow connects conversions to original click IDs and brings campaign performance into one reporting layer. The product is a practical fit for teams comfortable managing their own hosting and tracking infrastructure, especially when unlimited campaigns and domains matter.
The Free plan costs $0 per month and includes self-hosted affiliate tracking, unlimited campaigns and domains, no click or event caps, and AGPL-3.0 open-source code. It runs on a user-managed PHP and MySQL or MariaDB server, with custom tracking domains and configurable data retention. For platform connectivity, Simple Kuma supports Meta Conversions API, Google Ads conversions, custom postback URLs, S2S postbacks, and conversion pixels. Its REST API covers campaign, click, conversion, and statistics operations, while visitor and conversion logs can be exported as CSV.
Its strongest area is campaign-level measurement: statistics include clicks, conversions, cost, revenue, profit, ROI, and conversion rate, with bot detection available to help filter traffic. Campaign, offer, landing-page, and traffic-source management adds useful structure for media-buying workflows. The focus is narrower than a full affiliate management suite because affiliate portals and commission reporting are not part of the published feature set. Choose Simple Kuma for free, developer-oriented campaign tracking and infrastructure ownership; choose an alternative if partner-facing portals, commission administration, or a managed service are central requirements.
