How do I expose my Astro site to the internet?

Run `npx useburrow http 4321` alongside `astro dev`. Burrow returns a public HTTPS URL that tunnels to your local server over an outbound WebSocket, so it works behind any firewall or NAT.

Does Astro’s Vite HMR work through the tunnel?

Yes. Astro dev runs on Vite, and Burrow forwards WebSocket upgrades, so hot module replacement continues to work over the public URL.

Can I start the tunnel from my Astro config?

Yes — because Astro is built on Vite, the `vite-plugin-burrow` plugin boots a tunnel with your dev server. The plain `npx useburrow http 4321` command works identically without any config.
