Matomo
GPL analytics you host yourself — the compliance answer.
Matomo is the veteran of privacy-respecting analytics: GPL-3.0, self-hosted, with 100% data ownership, no sampling, and configurations that let it run without cookie consent in many jurisdictions. Around 21.7k stars and well over a decade of continuous development. It leans web analytics rather than product analytics — sessions, sources, campaigns, goals — with product-style funnels and cohorts available as paid plugins. If the reason you are on this page is a legal or procurement requirement rather than a product question, Matomo is usually the shortest route to a yes.
What it does well
- +Full data ownership with a mature, well-trodden self-host path
- +Can be configured to run without cookie consent in many jurisdictions
- +No sampling — the numbers are the numbers
- +Over a decade of development and a large plugin ecosystem
Where it falls short
- −Web analytics first; product analytics needs paid plugins
- −Interface feels dated next to PostHog and Amplitude
- −PHP and MySQL need tuning at high traffic
- −Several of the features people expect are premium add-ons
