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, custom events, autocaptured interactions, performance samples and JavaScript errors through a lightweight tracking script and an HTTP /api/track endpoint, and exposes a Bearer-key-authenticated Stats and Management API covering sites, sessions, users, goals, funnels, web vitals, session replays, organizations and teams. Since v2.8.0 Rybbit also runs a first-party hosted Model Context Protocol server at https://app.rybbit.io/api/mcp — 38 tools behind an OAuth 2.1 authorization server with PKCE, dynamic client registration and a 29-scope resource:action permission model — making it directly callable by AI agents. Rybbit publishes no OpenAPI. It can be self-hosted under AGPL-3.0, which ships the identical REST and MCP surface, 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, changelog, sandbox, API reference, getting-started guide, and 40 more developer resources.
