@y_taka Thanks, Takahito! Really appreciate the kind words, and yes, the ScreenCaptureKit permission dance was quite a trip 😅
To answer your question, Capso is 100% native Swift 6 + SwiftUI/AppKit, no Electron, no Torii, no Web Views. I wanted it to feel like a true Mac app, and the main capture/recording/annotation pieces are all independent Swift packages (CaptureKit, RecordingKit, AnnotationKit, etc.) that you can actually put into your project if you find them useful.
Hope it serves you well, and any feedback is always welcome on our GitHub!
