Open-source sandboxes for AI-built apps and live previews
sandboxd is an open-source tool for running AI-built apps in separate safe spaces. It creates a preview URL so people can see each result right away. It can pause unused sandboxes, which may lower server costs for AI agent products.
Key points
- A coding agent can build inside its own sandbox, separated from other users.
- Each app gets a preview URL for quick checking and sharing.
- It uses Docker and avoids Kubernetes, so the setup aims to stay simpler.
- Unused sandboxes can sleep and wake later, helping one server handle more work.
