LOCALHOST MIRROR · OPEN SOURCE

Tailnet-onlylocalhost tunnels.

Expose a local port to your phone, tablet, or another Mac over Tailscale, and never to the public internet. Every request is checked against your tailnet range before it reaches the port.

Run lm expose 3000, or click a port in the macOS menu-bar app; needs Node 18+ and Tailscale, no account, no public URL.
