App Store publishing 1

Mac app for designing, translating, and publishing App Store screenshots ButterKit is a native macOS application for creating, localizing, and publishing App Store screenshots and metadata. It lets developers capture screenshots directly from Xcode Simulator, import images from folders or Fastlane workflows, place them into editable 3D device frames, and enhance them with templates, fonts, gradients, backgrounds, and other design tools. ButterKit can translate screenshots and App Store metadata into up to 50 App Store languages, preview localized listings, batch-export assets, and upload designs directly to App Store Connect. It also supports offline workflows, on-device translation, AI agent automation through MCP, and Metal-powered editing at up to 120 frames per second.
