cloudflared is Cloudflare's tunnel client, and this one-liner creates an instant public URL on trycloudflare.com pointing at your local server on port 3000, with no account or config required. The URL dies when the process stops. For persistent tunnels, use `cloudflared tunnel create` and `cloudflared tunnel run` instead.
