Show HN: I've build a Tik-Tok styled app, but for GitHub (gitscroll.dev)

I built GitScroll: a TikTok-style vertical scroll app where you can quickly swipe through repositories.

Key features:

Learning Paths - Curated progressive journeys (React→Next.js, Python→AI/ML) with hand-picked repos for each step

Smart Quick Actions - Context-aware commands based on repo type. Libraries show install commands (npm/pip/cargo), templates show "Use Template", books show "Read Online"

Discovery Modes - Time Machine (explore 2015-2022), Hidden Gems (quality 50-500 star projects), Rising Stars, Contribute Mode (good first issues)

Three-column desktop layout - Trending panel, main scroll feed, detailed README viewer with contributor info

Favorites system - Save repos, share collections publicly with shareable URLs, privacy controls

Repository intelligence - Auto-detects if something's a library, tool, book, template, or config and adapts the UI accordingly

Technical challenges:

Scroll-snap CSS for smooth mobile experience proved trickier than expected GitHub API rate limiting required intelligent caching and query strategies Making learning paths feel cohesive while mixing curated + search results Balancing discoverability with overwhelming choice

Built with Next.js 15, Supabase for auth/favorites, GitHub API. Open to feedback on what discovery modes to add next.
