Cloudflare Releases `@cloudflare/computer` to Provide Isolated Workspaces for AI Agents
Cloudflare has launched `@cloudflare/computer` in early preview, an open-source library that provides AI agents with isolated virtual workspaces featuring file systems and command execution capabilities. The library dynamically orchestrates tasks between lightweight V8 isolates and full Linux containers depending on the workload. Traditional container-based environments for AI agents are resource-heavy and difficult to scale to billions of instances. By leveraging lightweight isolates for simple tasks and containers only when necessary, this library addresses a major scalability bottleneck in AI agent deployment. The library uses SQLite to power a virtual file system and offers two execution backends: an isolate-based backend that translates Shell commands to JavaScript using `just-bash`, and a container-based backend using Cloudflare Containers. It also includes built-in permission controls, auditing, and observability to prevent unintended file modifications.
## BACKGROUND
AI agents, especially those designed for coding, need to read source code, edit files, and run tests, which requires a persistent workspace and execution environment. Cloudflare Workers utilizes V8 isolates—the same technology that runs JavaScript in Google Chrome—to execute code with near-zero startup times and minimal memory overhead compared to traditional virtual machines or Docker containers.
