Running it yourself
Its compose file names these supporting services: postgres, redis. 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
