A design blueprint Spectr produced from GitHub. Scroll to look closer.
Clone GitHub iOS down to Primer dark, the reserved green, and the contributions heatmap
A pixel-faithful design token catalog reverse-engineered from GitHub iOS (the Primer design system on mobile), built around the repo home and code browser: owner/name header, tab strip, branch pill, file tree, and the README rendered inline. Real semantic palette, Mona Sans for UI and monospace for all code, SHAs, and diffs.
Everything you need to ship a GitHub-grade developer tool front end: exact Primer hex values, the reserved-green Code/Merge button, the iconic contributions heatmap ramp, semantic state pills (open/merged/closed/draft), the diff viewer, and the monospace code browser. Comes with framework-neutral specs plus SwiftUI, Expo, and Jetpack Compose guides.
Screens documented
- Repository home with owner/name header
- Code browser with path breadcrumb
- Pull request with diff viewer
- Issues list with state pills
- Contributions heatmap on profile
- Inline README card
What a Spectr spec includes
Screen-by-screen documentation, complete design system (color, typography, spacing), navigation map, component library, implementation notes, and a Claude Code prompt — everything an AI coding agent needs to build.
Turnaround
Most mobile apps produce a full spec in under 90 seconds from a single screen recording. Upload your own MP4 and watch the blueprint generate live.
Why not a design file?
Design files don't compile. A Spectr spec is optimized for AI coding agents like Claude Code — it produces working code on the first prompt, not layered artboards.
Target stack
Every spec targets Expo SDK 54 and React Native on an iPhone 15 baseline. The GitHub blueprint translates cleanly into an Expo Router app structure.
