@scops @Seferi Gomuks is almost flawless compared to anything not based on JS SDK. Well, Nheko is good too, but Qt is just not my cup of tea.
I use Element Web in Firefox (it's waay better than Electron) only for the sake of being able to paste images from system clipboard and voice calls.
Unfortunately Go itself is not that cross-platform. E.g. if you use PowerPC and musl you're out of luck.
