The catalog & greffons
The catalog is the library of apps you can graft onto a greffer. Each entry is a packaged, configurable app — no compose files to write.

What is a greffon?
A greffon is an app you can graft onto a greffer — Plausible, Ghost, Vaultwarden, Nextcloud, and more. Each greffon in the catalog ships with a description, a logo, and a set of configuration options that Greffon turns into a form.
Versions
A greffon can offer multiple versions. A version pins the app’s compose template and its configuration schema, so grafting a pinned version (like Ghost 1.0) always means the same thing. Pick a version when you graft.
Browsing
Open the catalog from the dashboard, filter by category, and pick an app. When you’re ready, head to Graft your first greffon.
The catalog is open source (Apache 2.0). You can add your own greffon recipes — see Extending the catalog (coming soon) or the catalog repo on GitHub.
