A growing category of tools now let you describe an app in plain English and have an AI write and run it for you. Most of them run entirely on the vendor's cloud, which means your code, your data, and your API keys all live on someone else's servers. Sandboxd takes the same idea — describe an app, get a working one — but runs the whole thing, including the AI agent's sandbox, on infrastructure you control. Sandboxd is an open-source AI application builder: you describe what you want in natural language, an AI agent scaffolds and iterates on the app inside an isolated container, and you get a live preview URL to test it as it's built. It includes in-browser code editing for manual tweaks, Git integration to keep history, and task checkpointing with undo so an AI-generated change that goes wrong can be rolled back. It's MIT-licensed and free to self-host; there's also a managed cloud option ($4.99/mo for a hosted app with a public URL, $79/mo for a fuller managed tier) for teams that don't want to run the infrastructure themselves.
