Computer

Cloudflare Computer gives an AI agent a working filesystem and a place to run code, both living inside a Durable Object with the authoritative state in SQLite. One entry point, workspace.runtime.exec, decides how that state gets executed, and the backend you pick decides the rest.

Three ship today. The container projects the SQLite state into a sandbox as a real FUSE mount with a full Linux userland. The isolate shell runs just-bash in a Dynamic Worker with no second store to keep in sync. The isolate JavaScript backend runs an ES module with Workspace-backed node:fs/promises and durable relative imports. A workspace can register several backends and connect them lazily, or skip the runtime altogether and use the filesystem alone. It is out as a preview for feedback: the APIs are unstable, and the maintainers say plainly that it is not ready for production.
