Self-Host Your
Supabase Proxy

You need Node.js 18 or higher and a free Cloudflare account. The CLI handles everything else: it installs dependencies, scaffolds the project, and deploys to Cloudflare Workers automatically. You can install Node.js from nodejs.org or using your system's package manager.

Yes. Cloudflare Workers free tier includes 100,000 requests per day, 10ms CPU time per request, and unlimited bandwidth. For most projects, this is more than enough. No credit card required to sign up.

Yes. The generated worker detects WebSocket upgrade requests and establishes a bidirectional relay to Supabase Realtime. Subscriptions, presence, and broadcast all work through the proxy. This is a major improvement over the basic worker generator tool.

Yes. After deployment, you get a .workers.dev URL by default. You can add a custom domain through the Cloudflare dashboard by configuring a Custom Domain or Route for your worker. See the Cloudflare docs for setup instructions.

The worker generator creates a basic HTTP-only proxy that you manually paste into Cloudflare's dashboard. The CLI generates a production-quality worker with WebSocket support, service filtering, CORS configuration, and auto-deploys it - all in one command. Think of the CLI as the generator's bigger sibling.
