Cloudflare previews @cloudflare/computer, an agent runtime spanning isolates and containers

Sources: announcement, source, discussion
Summary: Cloudflare published an early preview of @cloudflare/computer, a runtime that presents one interface over an isolate runtime and a container runtime. Both are backed by a durable virtual filesystem backed by SQLite. Cloudflare describes the release as an experiment and ships it as an open-source library on GitHub.
Why it matters: Putting a durable filesystem behind both execution modes means agent sandboxing stops being one container per agent, which Cloudflare argues does not scale.
