CLOUDEX

Run coding agents locally — then in the cloud.

Cloudex runs agent sessions in isolated git worktrees on your Mac. One click ports the same session to a Cloudflare Sandbox so it keeps running after you close your laptop — then syncs back via git.

Add idempotency keys to the charge endpoint and a test.

I’ll read the handler, add an Idempotency-Key guard backed by KV, then add a test.

[ How it works ]

1. Add your repo.

Cloudex spins up an isolated git worktree per session — one branch, one workspace — and the agent works only there.
2. Run the agent.

A streaming loop with fs / exec / git tools, plan mode, human-in-the-loop approvals, a live diff viewer, and run scripts — all on your Mac.
3. ⚡ Push to the cloud.

Send the same session to a Cloudflare Sandbox. It runs durably, survives your laptop closing, and syncs the result back via git for review and merge.

[ What’s inside ]

Local-first, isolated

One branch = one worktree = one review path. Your code never leaves your Mac unless you push it.

⚡ Push-to-compute

Durable runs on Cloudflare Workers + Sandbox. Close your laptop; the agent keeps going.

Plan mode & approvals

Read-only planning and explicit approval for risky tools — write, exec, browser, deploy.

Browser & MCP

Browser Run in the cloud, Playwright locally, and any MCP server — stdio or remote.

Checks & PRs

Git status, tests, lint, build — then open a GitHub pull request straight from a session.

Role lenses

Engineer, Simple, PM, or Designer. The substrate stays constant; the surface adapts.

Built on the Cloudflare developer platform — Workers AI, Durable Objects, Sandbox, R2, Browser Run.

[ Frequently asked questions ]

Does Cloudex use git worktrees?: └ Yes. Every session is its own branch and worktree, so runs stay isolated and reviewable.
Which models can it use?: └ Cloudflare Workers AI (free tier) by default — or bring your own Anthropic / OpenAI key. There’s also an offline mock loop.
Local or cloud?: └ Both. The exact same agent loop runs locally in a sidecar and in a cloud Durable Object + Sandbox.
How does the cloud run sync back?: └ Over git — a bundle (or native Artifacts remote). Fetch the result into your worktree, review the diff, and merge.
Is it free?: └ Local mode is free. ⚡ cloud runs use your own Cloudflare account (Workers Paid for the Sandbox).

One agent loop. Two homes.

Local when you want control, cloud when you want it to keep running.
