I hate it. It's useful for enterprise systems, since the people using that often need to access it from any device. Image/video/sound editing? Let me have an installed program and DON'T MAKE IT FUCKING ELECTRON. Most of the things I use don't connect to the internet, so I'd have to self host anyway, so I'd rather have the full application rather than run a localhost server.
As someone who 3D prints as a hobby, I prefer Chitubox over Lychee because the latter is an electron app, plus they force a 30 second ad wait when you click "slice".
