Running it yourself
Its compose file names these supporting services: postgres. Our rough heuristic, not the project's stated minimum: a small server (2 vCPU, 4 GB RAM), for example Hetzner CPX22 at €19.99 a month excl. VAT (checked 2026-10-13). Check the project's own requirements; this leaves out the time it takes you to run it. Compose file · Server price list

- Known gaps
- Each step is a script someone has to write in code, so a non-developer team will need technical help. The install ships with a default admin login that must be changed. The project recommends encrypting the database that holds stored credentials.
