I’ve been using the software Aurora to build character’s for a while and I love it, but it’s sadly no longer maintained and doesn’t have an official linux build. I’ve tried getting it to run with bottles, wine, proton etc. Are there any good character builders that natively support Linux?
Generally speaking, you’re unlikely to find native builds of apps for any OS if it’s easier to write a web app. This is one of those things that’s easy to make for browsers and doesn’t a localized program.
