Rybbit

Rybbit is an open-source, privacy-friendly web and product analytics platform positioned as a cookieless alternative to Google Analytics and Plausible. It ingests pageviews and custom events through a lightweight tracking script and HTTP /api/track endpoint, and exposes a Bearer-key-authenticated Stats API for sites, sessions, users, retention, and events. Rybbit can be self-hosted under AGPL-3.0 or consumed as a managed cloud service.

Rybbit publishes 3 APIs on the APIs.io network: Analytics API, Event Tracking API, and Sessions API. Tagged areas include Analytics, Web Analytics, Product Analytics, Privacy, and Open Source.

Rybbit’s developer surface includes authentication, engineering blog, documentation, and 10 more developer resources.
