I love this project but I really wish there was an alternative in Linux to using webkit. It's just not a particularly compelling browser engine for me.

I'd love a developer centric blog post on the plugin system that leads this roadmap post. Sounds like it's already mature. Having 2-3 examples of it in use, and an example of diy-ing something new (maybe do an ambient light sensor or something) would be rad & mad helpful.

So this will be a competitor for capacitor.js? Will I be able to talk to bluetooth, gps, notifications?

It's a competitor for electron.

Which has smaller binaries and runs faster!

Electron doesn't run on mobile though.

Tauri plans to ship for mobile.

They mentioned being able to write plugins in Swift and Kotlin, so yes.
