What is it?

Composery is a secure cloud computer with a powerful UI, usable from any phone or browser.

It's like VS Code, but it sits on a server, and is thus reachable from any browser or phone whenever. You get a real Linux system: install packages, edit system files, run agents, build projects - and that state survives restarts. The runtime is a container, so durable state comes from one volume mounted at /data (see Persistence).

The environment

  • You are user, a normal account with passwordless sudo - root whenever you need it.
  • cron runs, so crontab -e schedules jobs.
  • For incoming network requests, see webhooks.

Your changes persist across restarts through the persistence daemon, which writes only your deltas to /data. Configure the runtime with environment variables.

Running Composery

  • Self-host it - deployment guides for Render, Railway, DigitalOcean, Fly.io, Koyeb, a VPS, Kubernetes, and other platforms (Coolify, Dokploy, Elestio, ...).
  • Composery Cloud - the hosted offering at composery.io, running the same image, but managed for you.
