cloudflare/computer
cloudflare/computer is an open-source runtime for Agent developers to persist work files and run commands or code in containerized or isolated environments, producing reusable artifacts and execution results.
Tool overview
Adoption judgment: this is worth piloting as infrastructure for Agent sandboxes and persistent workspaces, but its recent attention should not be treated as proof of production maturity. A more accurate description is an open-source runtime that gives an Agent a durable workspace and selectable execution backends. It is not a ready-made Agent, a model API, or a virtual desktop computer.
In practice, the project lets an Agent keep files in one workspace while choosing among a full container, Isolate shell, and Isolate JavaScript for different tasks. The container is aimed at workloads needing Linux tools, real binaries, or networking; Isolate shell is positioned for fast common shell operations; and Isolate JavaScript runs ECMAScript modules and can return structured results. The concrete outputs are persistent files, command results, code-processing artifacts, and reusable intermediate state rather than only one-off chat text.
The main implementation threshold is designing workspace lifecycles, backend selection, permissions, dependency boundaries, and networking behavior, while accounting for differences between containers and Isolates.
