Cloudflare is hiring: 445 open roles

Overview

Cloudflare Computer keeps a workspace filesystem in a Durable Object's SQLite and exposes it through one `workspace.runtime.exec` call. Backends are a FUSE-mounted sandbox container (via the `computerd` daemon), a just-bash shell in a Dynamic Worker, or an ECMAScript module in a Dynamic Worker. The repo includes examples for agents built with pi, TanStack AI and `@cloudflare/think`, plus an MCP example. It is labeled preview only, with unstable APIs.

Who it is for: Cloudflare developers building agents that need a persistent workspace

Strengths

One exec entry point across container, shell and JavaScript backends, which connect lazily
SQLite in the Durable Object is the single authoritative store; isolate backends use Workers RPC with no sync
Container backend gives a full Linux userland through a real FUSE mount
Many runnable examples: pi, TanStack AI, Think, MCP, egress policies, Artifacts

Weaknesses

README states preview only, unstable APIs, and not suitable for production
Tied to Cloudflare Workers, Durable Objects and Dynamic Workers
Docs under docs/ are a forward-looking spec, not a description of current code
Unsolicited pull requests are not accepted

What it needs

TypeScript
Needs Cloudflare Workers, Durable Objects, Dynamic Workers, Cloudflare Containers, just-bash

How to choose

Choose the framework you want to live with; templates are thin and the framework is the real dependency.
Check where state lives (Durable Objects, Postgres, a managed platform) and whether that fits your hosting.
Favor templates that ship tests or an eval hook so agent changes can be checked.
