• trayscale

  6 238 0.0 Go

  An unofficial GUI wrapper around the Tailscale CLI client.

  Yep. I was using manual WireGuard tunnels for that, but everytime I added a machine I had to configurations from both sides with manual key swaps, plus the fact that it I wanted direct connections between each machine the configuration would literally have increased exponentially. Tailscale handles all of that for me. Literally. It's primarily an automatic WireGuard tunnel coordinator. I just have to install it and log in and voila, it just works. I like it so much that I've actually got a project that wraps a GUI around Tailscale for Linux.
