At least it is a mile better than the abomination named Electron.
Each Electron app has both Chromium and NodeJS bundled. Tauri only use platform-specific webviews, and Rust is a compiled language with no GC and no runtime.
Yes, it does suck sometimes, but for UI then your frontend framework should work all the same 99% of the time. If your app is related to audio/video playback or you want to use newer features of Web standard such as webGPU, then it will be trickier.
