preview-environments

Open-source, self-hosted AI app builder — an agent builds real apps in isolated sandboxes on your own server, each live at a preview URL. Self-host in one command. MIT.

Free, self-hosted alternative to Vercel, Heroku, Railway, Coolify and Dokku. Push to git, get HTTPS, logs, metrics and one-click rollback on your own servers. One Go binary, no Kubernetes.

Rebuild a local twin of your app on every push, replay approved business journeys, and report a GitHub check.

A disposable copy of your production stack for every pull request: masked Postgres, contained third-party APIs, and agents that use your app like people.

Isolated databases for every AI agent branch. Build, test, and migrate in parallel. Production stays untouched.

Per-PR preview environments on your own host, reachable only through your tailnet. Each PR gets its own containers and a copy of the baseline's data; HTTPS via Tailscale or one wildcard certificate. A GitHub Action plus a bash engine on Docker Compose.
