I also tried the same options and was not satisfied by any. Good luck with your program! I would be curious to try it when it’s ready.

I was also sceptical, but then I started to use codecompanion.nvim with Hugging Face recently. It works quite well and can be helpful for coding.

Tailscale offers a paid Mullvad integration, where you can select most Mullvad servers as exit nodes. Works quite well.
