Yep. Been working on Polypane full time since 2019 as a solo developer. Electron based, available on mac, windows and linux, in x64 and arm versions. Its subscription based and I release a new update roughly every month. It was a side project before that but I started charging for it when I went full time. https://polypane.app. - Source: Hacker News / over 2 years ago

With webviews however, that model doesn't make much sense: the... - Source: Hacker News / almost 3 years ago
