We just not there yet. Tauri tries to be Electron or React, where you write only once and use everywhere. This is very cost efficient. So even though it's of course not perfect overall, but it is the perfect alternative, that brings web apps closer to native-like experience. Small but important step to greatness.
In the end the question is: Election or Tauri? And not a debate on whether web frameworks are bad etc.
Do you know what this even is? It's not marginal at all. Check the comparisons of Tauri and Electron. And it does not use Chrome. Electron also doesn't use Chrome.
But what if all things cost Β£5?
