TailMux is a macOS and Linux tool that lets you access multiple independent Tailscale tailnets simultaneously from a single machine. Unlike the official Tailscale client, which keeps only one tailnet active at a time, TailMux runs an isolated embedded Tailscale node per profile and routes requests by hostname suffix. A request to nas.home lab.ts.net is handled by the profile that owns that suffix, with strict no fallback isolation — traffic never bleeds between profiles. Supported access paths include browsers (via a generated PAC file), SSH, the command line (curl, git, npm), and local TCP tunnels. TailMux does not add a system wide VPN interface or modify the official Tailscale session, so your everyday Tailscale setup remains untouched.
