OSI-licensed only · self-hostable
Mixpanel tracks user events and turns them into funnels, retention curves and cohorts. Open-source tools cover this from heavyweight product-analytics suites to simple privacy-friendly web analytics, and you can keep the event data on your own servers.
Every tool below is under an OSI-approved licence (MIT, AGPL-3.0, GPL-3.0), checked against its repository. The tools differ in depth: PostHog and OpenPanel go after Mixpanel's event analysis, while Plausible and Umami focus on lighter website metrics.
Licences checked against each repository on November 7, 2026.

Public source code, but under licences the Open Source Initiative doesn't approve. Fine to use; read the terms first.
Source for rudder-server is public, but the Elastic License 2.0 restricts offering it as a managed service, so it is not OSI-approved. It is an event pipeline rather than an analytics UI.
Quick answers to common questions
Yes. PostHog is the most complete, and OpenPanel is a focused alternative for event analytics.
Most of the repository is MIT, but the ee/ directory is under a separate licence.
Plausible, Umami and Matomo emphasise privacy and can be self-hosted so the data stays with you.
Mixpanel offers data export. Event schemas differ between tools, so plan to map event names and properties and test with a small slice.
Not for PostHog, Plausible, Umami, Matomo or OpenPanel. Jitsu is meant for routing events to a warehouse.
List it on TechLogHub and we'll review it for this page.
