What's a greffer?
A server you own, running apps you chose, paying zero rent to the cloud.
Greffon turns any machine — Windows, macOS, or Linux — into a greffer. Install once. Run it indefinitely. Your apps, your hardware, your rules.
- Linux VPS — Debian, Ubuntu, Fedora, Arch
- macOS — Mac mini, MacBook
- Windows — desktop or laptop
- Raspberry Pi — ARM64
- NAS / homelab — Synology, TrueNAS
Three steps. No DevOps.
Turn your machine into a greffer.
One install command. Works on Windows, macOS, or any Linux distro. Set up your greffer in minutes.
Open the catalog.
24 self-hosted apps ready to graft — Plausible, Ghost, Nextcloud, GlitchTip, and more. No YAML editing.
Graft what you want.
Click deploy. Each app goes live in seconds. TLS and routing handled — your data never leaves your infrastructure.
Real apps, ready to graft.
Open-source apps pre-packaged for your greffer. Deploy from the catalog. Yours to keep.
Who runs a greffer?
Indie developers with a VPS
Stop renting cloud capacity for every side project — run them on the VPS you already pay for. Run the apps you want, on the hardware you already rent, for the price of the VPS alone.
Homelabbers
Your Raspberry Pi, your Synology, your old ThinkPad or Mac mini — any of them can be a greffer. One dashboard for every app, updates and TLS handled.
Self-hosters tired of YAML
Twenty compose files, twenty Nginx configs, twenty TLS renewal calendars. Or: one greffer, click to graft, done.
Where we stand on code, money, and your data.
Three commitments we're making now. The greffer and catalog are already open source (AGPL v3 and Apache 2.0). The manager is AGPL v3 too, with its source publishing at launch.
- Free to self-host. Pay to resell.The whole stack runs on your hardware. We host nothing you can't host yourself. Greffon Hosted is a convenience — not a lock-in.
- No feature gating on self-hosted. Ever.Same catalog, same greffons, same code — only the convenience of us hosting the manager differs.
- Your data never leaves your infrastructure.Greffon routes nothing through our servers. Every greffon runs on your machine, talks to your database, writes to your disk.
Our licensing commitment
Free to run for yourself, free to modify for yourself. If you distribute or run it as a service for others, your changes stay open too. The greffer and catalog are open source today (AGPL v3 and Apache 2.0); the manager is AGPL v3 as well, with its source publishing at launch.

Questions, answered.
What is a greffer?
A greffer is any machine you own running the Greffon worker: a Linux VPS, a Mac, a Windows PC, a Raspberry Pi, or a NAS. You install it with one command, then deploy apps onto it from the catalog.
Do I need DevOps skills?
No. Greffon handles TLS, routing, and config for you. You pick an app from the catalog and click deploy. There is no YAML to edit and no reverse proxy to set up.
What hardware do I need?
Anything that runs Docker: a Linux VPS, macOS or Windows via Docker Desktop, a Raspberry Pi (ARM64), or a NAS. Heavier apps want more memory and disk, but most run comfortably on modest hardware.
Is my data actually mine?
Yes. Your apps and their data live on the greffer you control. Greffon orchestrates deployments; your files never have to leave your own infrastructure.
What does it cost?
Self-hosting is free, with no feature gating. Greffon Hosted (launching soon) runs the Manager control plane for you on a simple monthly plan, while your apps still run on greffers you own.
What if I stop using Greffon?
Your greffers and their data stay on your hardware. There is no proprietary lock holding your apps, so you keep running them on your own terms.
Ready to turn on your greffer?
Install in minutes. Deploy each app in seconds. Your server, your apps.
