The Portmaster UI was previously built with Go, acting as a base layer which then loaded a OS-provided webview for the UI. Unfortunately, the OS-provided webview had many issues which forced us to rethink and re-write the UI.
While planning this re-write, we did invest a lot of time to research different approaches. Sadly, at that point, our evaluation concluded that using anything but Electron would require us to invest a lot of time and effort: We would either have to build a viable solution from scratch or bend over enough to fit into existing ones.
