ΛNΛLOG

ΛNΛLOG is a self-hosted analytics app that receives named events over HTTP and shows them on a dashboard. Its server is a Node.js process that stores events in MongoDB, PostgreSQL, Redis or SQLite, and the same process can serve the static frontend when ANALOG_STATIC_SERVER is set. A site sends an event with a POST request to the /api/events endpoint, naming the event in the body, and the dashboard reads the stored data back with a GET request to the same path.

The README covers a local run with npm, a Docker build from the repository’s Dockerfile, and deploys to Koyeb, Netlify, Render and Vercel from a copy of the repository. The project keeps its configuration in environment variables, which the README lists in one table.

Worth knowing

The optional ANALOG_TOKEN protects requests, and ANALOG_PROTECT_POST extends the protection to POST requests. The README warns that scheduled clean-up on Netlify and Vercel may not run because of runtime limits. The PostgreSQL section asks for a transaction pooler connection. The release line is pre-1.0.
