How to self-host Alf.io

Alf.io runs on Java. The project's own install guide is the place to start; most people put it on a small server with Docker and a reverse proxy for HTTPS.

  1. Get a server: a home server, a VPS, or a managed app host.
  2. Install it the way the project's docs describe, usually with Docker Compose.
  3. Put it behind HTTPS and set up backups before you add real data.
  4. Update it regularly. Watch the project's releases.
