hostc

Localhost to the edge.

Secure, fast, and frictionless edge tunnels. Powered by Cloudflare Workers.

hostc is a modern, lightweight, and zero-configuration tool to instantly expose your local HTTP and WebSocket services to the public internet. Built entirely on top of Cloudflare Workers and Durable Objects for global low-latency edge networking.

• Zero Config: Just run one command and get a public HTTPS URL.
• WebSocket Support: Seamlessly proxies WebSocket upgrades (ws:// -> wss://) out of the box.
• Edge Powered: Traffic is routed through Cloudflare's massive global network network.
• Self-Hostable: You can easily deploy the worker to your own Cloudflare account.

You don't even need to install anything if you have Node.js. Just run:

npx hostc 3000

Or, install it globally for frequent use:

npm install -g hostc

hostc 3000

Public URL: You'll instantly get a URL like https://t-a1b2c3d4.hostc.dev that routes traffic directly to your http://127.0.0.1:3000.

hostc is still early, and the focus right now is making the core tunnel experience solid before adding more surface area.

• Harden tunnel routing, connection lifecycle, and error-page behavior.
• Polish the CLI UX around reconnects, local server failures, and terminal output.
• Improve self-hosting and local development docs.
• Add better operational visibility for the Worker and Durable Object path.

• Reserved or custom subdomains.
• Basic access control for shared tunnels.
• A cleaner hosted onboarding flow beyond the current waitlist.

This project is a Monorepo managed by pnpm.

• Node.js 18+
• pnpm v8+
• A Cloudflare account (if you want to deploy the worker yourself)

1. Install dependencies

   pnpm install

2. Run the Cloudflare Worker locally

   pnpm dev:workers

3. Run the CLI locally against your local worker

   cd apps/cli
   pnpm dev
   
   # Or using the environment variable with the built CLI:
   HOSTC_SERVER_URL=http://127.0.0.1:8787 hostc 3000
