Cli is already available for linux (which provides the same functionality, just that you have to use the web browser instead of desktop window)
For desktop app I plan to add support soon. The delay is because there are too many variations (appimage/flatpak/deb/snap) and I need to figure out which one to support etc. I use linux myself (NixOS).
The project comes with a flake.nix file, you can try that (you would still need to build it manually, I use the flake only to bring the dev environment, not to build the final package). I don't plan to submit to nixpkg myself or any other package managers. I will only focus on binary builds that's downloadable from release page. I don't have any experience with maintaining distro level packages, and I don't think I can figure out the details and keep it maintained. I will leave it to the community to figure that out.
