ButterKit is a native macOS app for Apple developers, automating the App Store publishing workflow. Capture screenshots from Xcode Simulator into photorealistic 3D frames. Translate content into 50 languages with AI or 18 on-device, making localization trivial. Upload directly via the App Store Connect API. Integrate with Fastlane and CI/CD pipelines. Use templates, custom fonts, and 3D callouts. It helps your app show up in native language search results across every market Apple supports.
