The CurseForge localization system is absolutely dire and we're questioning if the supposed benefit of easy access is really worth it. Alternative more generic systems exist like Weblate - we could possibly look into using those instead.

One challenge of note; the CF import process accepts a Lua chunk and parses it for us. Any alternative won't know about Lua so we'll need some script support to parse our strings and put them into an intermediate format (.po, .ts, .csv, whatever is most convenient - the hard work is more in the parser).

Figured I'd mention it:

Another website I see used a lot for open-source projects on GitHub, aside from Weblate, is called Crowdin.
