docs: add Cloudflare Sandbox SDK deployment guide (#57)
* docs: add Cloudflare Sandbox SDK deployment guide

- Add docs/deploy/cloudflare.mdx with full deployment guide
- Add examples/cloudflare/ with working Worker code
- Update docs navigation to include Cloudflare option
- Update deploy index page with Cloudflare card

The example shows how to run sandbox-agent inside a Cloudflare Sandbox

* fix: guard server startup to avoid port conflicts

Add health check before starting sandbox-agent to prevent 'address already
in use' errors on subsequent requests. The isServerRunning() function probes
the health endpoint to determine if setup should be skipped.

* fix: default cloudflare/sandbox:0.7.0 (latest does not exist)

* feat(cloudflare): add React frontend and improve deployment docs

- Add React + Vite frontend for Cloudflare example with sandbox-agent SDK
- Update ensureRunning to poll health endpoint instead of fixed wait
- Fix SDK fetch binding issue (globalThis.fetch.bind)
- Update docs with .dev.vars format warning and container caching tip
- Use containerFetch proxy pattern for reliable local dev

Cloudflare Sandbox Agent Example

Deploy sandbox-agent inside a Cloudflare Sandbox.

Prerequisites

  • Cloudflare account with Workers Paid plan
  • Docker running locally for wrangler dev
  • ANTHROPIC_API_KEY or OPENAI_API_KEY for the coding agents

Setup

  1. Install dependencies:
pnpm install
  1. Create .dev.vars with your API keys:
echo "ANTHROPIC_API_KEY=your-api-key" > .dev.vars

Development

Start the development server:

pnpm run dev

Test the endpoint:

curl http://localhost:8787

Deploy

pnpm run deploy

Note: Production preview URLs require a custom domain with wildcard DNS routing. See Cloudflare Production Deployment for details.
