ButterKit Product Information

What is ButterKit?

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.

How to use ButterKit?

Download ButterKit for macOS, create a project, then capture screenshots from Xcode Simulator, drag in PNG or JPG files, or link a Fastlane or image folder. Place screenshots into 3D device frames, customize templates and design elements, and create polished App Store artwork. Translate screenshots and metadata into supported languages, preview each localization, and export the assets or upload them directly to App Store Connect. The free version includes watermarked exports, while Pro removes the watermark and unlocks App Store Connect management.
