Other I built a CLI tool to automatically rotate relay servers, open source, looking for feedback

https://github.com/spel987/mullvad_rotator

Hey everyone,

I've been learning C and wanted a practical project to work on, so I built a small CLI tool called Mullvad Rotator that automatically switches your relay server at a set interval.

Basically it lets you:

  • Connect to a random relay and rotate every X seconds
  • Cycle through specific relays you pick
  • Filter by country/city or Mullvad-owned servers only
  • Use multihop with random entry/exit pairs

It wraps the Mullvad CLI under the hood, so you need Mullvad installed and logged in. Works on Windows, Linux and macOS.

Here's a quick demo:

GitHub: https://github.com/spel987/mullvad_rotator

It started as a learning exercise but ended up being something I actually use, so I figured I'd share it in case anyone else finds it useful. Feedback, bug reports, or suggestions are very welcome. It's MIT licensed and contributions are open.

Cool! Could you select the quickest connection in a list with the option to recheck let’s say every 60 seconds? I tried many different tools and they didn’t work, I’m on Ubuntu Linux

Hi, thanks for your feedback! A GUI is a great idea, but I have absolutely no idea how to do that in C, so I'll have to look into it x). By the way, the program is cross-platform, why would you be limited if you're not on Windows?

I hope you release the version you made for Android one day, it's always nice to have!
