Does CurseForge App run on Linux?
Verdict: Yes
Yes. CurseForge publishes a Linux download of its mod manager alongside the Windows and Mac ones, so your Minecraft modpacks and other mod collections come with you.
The CurseForge download page offers the app for Windows, Mac and Linux. There is nothing clever to arrange: you pick the Linux download, install it, sign in, and your profiles are there.
This matters most for Minecraft, where CurseForge is how many people install and update modpacks. Minecraft itself runs on Linux, so the pairing works the way it did on Windows. Mods for other games follow the same pattern, though whether the game runs on Linux is a separate question from whether CurseForge can manage its mods.
Copy your existing instance folder across from the Windows machine if you want to keep worlds and settings. Mods and packs are downloaded again on the new install, so a slow connection is the main cost.
If a game you mod is Windows only and you are playing it through Steam's Proton feature, which runs Windows games on Linux, expect some fiddling to point CurseForge at the right folder. That is a quirk of where Proton keeps game files rather than a fault in CurseForge.
