Yeah, it's a Tauri app, which makes the claim in the README about it being a native app also rather a lie.

Did Tauri ever figure out how to run performantly on Linux, or are they still using webkit2gtk? They were looking at integrating Servo last time I checked, but I have no clue how far they've progressed with that since.

I dont think the author knows what either of those things are. The whole thing is vibed.

This ticket tries to explain it: https://github.com/l0ng-ai/openidea/issues/568

Building consistent frontends for all platforms isn’t easy in rust, so they use web standards for that.

Things like these make me question the provided benchmarks too
