Shipper and ButterKit help Apple developers turn app screens into editable App Store screenshots, localize them, and upload them to App Store Connect. Their core capabilities overlap, but there are meaningful differences in pricing, design tools, capture sources, and AI integration.
Shipper focuses on editable screenshot compositions, Adaptive Screenshot Specs, and Codex delegation through Shipper Plugin. ButterKit supports adjustable 3D device frames, Xcode Simulator and linked capture folders, and an MCP server for multiple AI clients.
This comparison uses current public documentation, not a hands-on design quality or speed benchmark. For more on adapting copy across languages, see our guide to creating localized App Store screenshots.
