What is Greffon?

Greffon turns a machine you own into a greffer — your own app server — and lets you graft self-hosted apps from a catalog in one click. Your hardware, your data, no cloud rent.

The words

  • greffer — a server you own, running the apps you chose.
  • greffon — an app you graft onto a greffer (Plausible, Ghost, Vaultwarden…).
  • graft — to install a greffon onto your greffer.
  • catalog — the library of greffons ready to graft.

How it fits together

Greffon has two parts: the Manager (the control plane — the dashboard and API you log into) and the greffer (the worker that runs on your server and hosts your greffons). You point a greffer at a Manager, accept it once, and graft apps from the catalog.

Open and honest

The greffer and catalog are open source (AGPL v3 / Apache 2.0). Linux is the recommended host; macOS and Windows are supported via Docker Desktop.
