Your agent needs a computer, not a container — introducing @cloudflare/computer

Cloudflare’s open-source @cloudflare/computer runtime gives each agent a durable workspace and chooses between fast isolates, full Linux containers, and browser backends instead of pinning every task to a container.

The agent harness runs in a Durable Object while a shared SQLite-backed filesystem spans execution backends. File, git, and shell operations are gated, audited, and observable; lightweight file manipulation can stay in an isolate, while native binaries and full Linux tooling use a container on demand. It is an early preview, so the architecture is more interesting than production readiness today.
