I second this. I was using a Cloudflare Tunnel, which worked but meant I had to jump through some hoops setting up an email auth flow that then sent me a verification code

Now I use Tailscale (which is free for a single-user account) and it works excellently, without the Cloudflare dependency. No login necessary through the browser like with Cloudflare Tunnel, because you're already authed with Tailscale on the device.
