Where Developers Find Wisdom
GitGyan is an open-source, AI-powered GitHub discovery engine that scans 500,000+ repositories weekly, scores them by signal strength, and surfaces the ones gaining momentum — before they go viral.
GitHub creates 500,000+ repositories every week. Most are noise.
GitGyan filters that down to the repos that actually matter — using a signal scoring algorithm that weighs star velocity, momentum, fork adoption, and community activity. Every high-signal repo gets an AI summary powered by Claude Haiku, so you understand what it does and why it matters in seconds.
544,476 repos on GitHub this week
11,006 analyzed by GitGyan AI
20 high-signal picks today
- 🔥 This Week — Fresh repos gaining momentum right now (not old viral repos)
- ✦ AI Summaries — Claude Haiku analyzes each repo: what it does, why it matters, who should care
- ⭐ Signal Scoring — Algorithm weighs star velocity, momentum, fork ratio, and community health
- 🔥 Viral Detection — Catches repos going viral before mainstream discovery
- 🌐 10 Languages — Rust, Python, TypeScript, Go, C++, JavaScript, Swift, Kotlin, Java, C
- 🤖 13 AI Topics — Claude, MCP, LLM, AI-Agent, OpenAI, LangChain, RAG, and more
- 📊 Nightly Sync — Automated GitHub sync runs at 2am UTC every night
- 💬 Community Feedback — Leave feedback with GitHub profile verification
| Technology | Role |
|---|---|
| Claude Haiku | AI summaries — $0.0002/summary, <2s response |
| Next.js 16 | Full-stack React — frontend + API routes + cron jobs |
| Supabase | PostgreSQL — repos, daily stats, feedback, viral alerts |
| GitHub Search API | Data source — nightly sync across languages and AI topics |
| Vercel | Deployment + cron job scheduler |
| TypeScript | End-to-end type safety |
Every night at 2am UTC:
┌─────────────────────────────────────────┐
│ Phase 1: Fetch by Language │

signal_score (0-100) =
stars_gained_today × 0.40 (momentum)
vs_7day_average × 0.30 (acceleration)
fork_ratio × 0.20 (adoption)
issue_activity × 0.10 (community health)
A repo that doubles its historical star average scores 90+. claw-code scored 97 the day it hit 100K stars.

□ Campus workshops & partnerships
Building GitGyan is remarkably affordable:
Claude Haiku summaries: $0.0002/summary
11,000 summaries total: ~$3.00
Domains (gitgyan.dev): $24/year
Vercel (Hobby plan): Free
Supabase (Free tier): Free
─────────────────────────────
Total cost to run: ~$27/year + AI costs
- Vercel's 5-minute timeout — Split long cron jobs into separate phases
- Calculate AI costs first — Haiku is so cheap you'll over-engineer caching
- Separate sync from reads — Nightly cron writes to Supabase, users read from Supabase (zero GitHub API calls during the day)
- GitHub
total_count— One API call withper_page=1gives you the global count - Frontend without a designer — CSS variables + inline styles + Claude = production UI at $0
- 🌐 Live at: gitgyan.dev
- 📊 Repos analyzed: 11,000+
- 🔄 Syncing since: April 2026
