Draw your GitHub contribution story — one commit at a time.

GitHub Pattern Generator is an open-source web tool that allows you to visually design custom GitHub contribution graph patterns and export them as a pattern.json file. This JSON file can then be used with automated commit scripts to render beautiful patterns on your GitHub contribution graph.

GitHub contribution graphs are like a canvas made of pixels. This project turns that canvas into a pattern editor where you can:

• 🖱️ Click to draw custom contribution patterns
• 🎯 Design shapes, text, or symbols
• 📦 Export the design as a pattern.json file
• 🤖 Use the JSON file with auto-commit tools to apply the pattern

All of this happens directly in your browser — no setup required.

• 🎨 Visual & Intuitive – draw patterns instead of guessing commit dates
• ⚡ Fast & Lightweight – built with plain HTML, CSS, and JavaScript
• 🔁 Reusable – export patterns as JSON and reuse anytime
• 🧩 Automation Friendly – perfect for commit automation projects
• 🌍 Open Source – customize the UI, add features, or improve performance

Whether you want to create GitHub art, test automation scripts, or just experiment — this tool makes it simple.

The project is hosted using Firebase with CI/CD Pieplines:
