# sandboxd

> sandboxd (v0.3.22, October 2026, beta) is one Go program driving Docker on a Linux server. Each app gets its own container; an agent (OpenCode by default, or Claude Code) builds it from your prompt and serves a live preview URL. It has a web console with file editor, git diff and push, undo, plus 80+ one-click open-source app recipes and a full API. OpenCode runs on free hosted models with no key; local models are not documented. Uses container (not VM) isolation and API auth is off by default. Public URLs need your own domain/TLS or paid sandboxd Cloud. MIT.

## What it replaces
- Lovable: Build a full-stack web app from a chat prompt, See the running app update as it is built (partial). Prompt-to-app with live previews on your own server; no visual editor or built-in database/auth for your apps.
- Bolt.new: Build a full-stack web app from a chat prompt, Run and preview the app in the browser (WebContainers) (partial). Apps run in Docker containers on your server rather than in the browser; Linux host needed.
