DevImpact is an open-source platform that compares software developers based on their real impact in the open-source ecosystem — not just raw numbers.

It evaluates developers using a smart scoring system that considers:

• Repository quality 📦
• Pull request impact 🔀
• Community contributions 💬

Traditional metrics (followers, stars, commit counts) are often misleading.

DevImpact focuses on:

• ✅ Quality over quantity
• ✅ Real contributions to valuable projects
• ✅ Fair comparison between developers

Each developer is evaluated using three main scores:

Measures the quality and impact of repositories owned by the user.

Factors include:

• Stars ⭐
• Forks 🍴
• Watchers

Measures contributions to other developers' repositories.

✔ Only merged PRs are counted ✔ PRs to the user's own repositories are excluded

Factors include:

• Target repository quality
• PR size (additions/deletions)
• Repository popularity
• Contribution diversity

Measures community engagement.

Includes:

• Issues opened in external repositories
• Discussions participation

⚠️ Does NOT include commits or PRs (to avoid duplication)

The final score is a weighted combination:

Final Score =
0.45 × Repo Score +
0.45 × PR Score +
0.10 × Contribution Score

👉 The ContributionScore is capped to prevent abuse.

• ❌ No self-inflation (own PRs excluded)
• 📉 Diminishing returns to prevent spam
• 🎯 External impact is prioritized
• ⚖️ Balanced scoring between builders and contributors

• 🔍 Compare two GitHub users side-by-side
• 📊 Visual score breakdown (charts & insights)
• 🧠 Smart ranking system
• 🌍 Localization support (EN / AR)
• ⚡ Fast API powered by GitHub GraphQL
• 🧩 Extensible scoring system

• Next.js (App Router)
• TypeScript
• Tailwind CSS
• Recharts

• Node.js + Express
• GitHub GraphQL API

Run the entire platform (Web App UI + PostgreSQL + Redis) in 2 simple steps:

# 1. Copy environment template and set GITHUB_TOKEN
cp .env.example .env

# 2. Start full platform
docker compose -f ops/docker/docker-compose.yml up -d --build

Then open http://localhost:3000 in your browser!

1. Install dependencies:

   pnpm install

2. Configure environment:

   cp .env.example .env

3. Start local database & Redis:

   pnpm db:up && pnpm redis:up

4. Run development server:

   pnpm run dev

5. Calculate leaderboard scores manually:

   pnpm leaderboard:calculate

The leaderboard score updates run via a dedicated background worker container using Docker & Supercronic.

For complete local setup, Docker Compose instructions, GHCR publishing, and VPS deployment documentation, see ops/README.md.

# Quick worker setup (pulls & runs published image)
cp .env.example .env
docker compose -f ops/docker/leaderboard-compose.yml pull
docker compose -f ops/docker/leaderboard-compose.yml up -d
