ButterKit has changed a lot since it launched! New features, hundreds of improvements, and now macOS 27 support. It was time for a new look to match: a new logo, wordmark, and color palette built around one idea: simple ingredients, iterated on repeatedly, produce something that rises.
ButterKit 2 rebuilds the canvas on SwiftUI for a noticeably faster, smoother, more buttery experience. Plus rotate any image, logo, or badge, and much faster App Store Connect uploads.
Callouts let you highlight features and UI in 3D space alongside your devices. Plus performance boosts and refreshed onboarding.
Add translation instructions in Project Settings so AI models know your tone, capitalization rules, and what not to translate.
ButterKit now supports all 50 App Store Connect languages, adds Apple Vision Pro support, and lets AI agents place images on your artboards.
