Connect your machine
On‑prem, mini‑PC, VM or private cloud. Lightweight encrypted agent.
Pick an app
Choose from the Store and set variables & secrets.
Install & operate
Atomic deploys, updates and observability in one place.
Run it on hardware you own
A greffer is any machine with Docker — a $5 VPS, a mini-PC, your Mac, an old laptop. No cloud lock-in, no rented compute.
What you need
- Docker. Linux, macOS, or Windows.
- Admin or root access, and an outbound internet connection.
- For LAN-only use (dev or home network), nothing else.
- For external access: port forwarding + dynamic DNS, or a tunnel like Cloudflare Tunnel or Tailscale. Stem will ship a built-in option.
