- 🎨 Interactive controls - Pause, play, adjust speed, and navigate through each step
- 🌓 Dark/Light themes - Beautiful UI that adapts to your preference
- 📊 Performance metrics - Track comparisons, swaps, and complexity in real-time
- 🧩 Multiple data structures - From sorting algorithms to trees and graphs
- 🎓 Educational focus - Clear explanations and pseudocode for every algorithm
Coming Soon: Screenshots and GIFs showcasing Vizit in action!

Architecture Highlights:
- ✨ Dedicated pages - Each algorithm has its own route (no dynamic routing)
- 🧩 Component-based - Reusable visualization components
- 📝 Type-safe - Full TypeScript support
- 🎨 Modular - Easy to add new algorithms (see guide)
We love contributions! Vizit is open-source and welcoming to developers of all skill levels.
Vizit is Hacktoberfest-friendly! We've tagged issues with hacktoberfest, good-first-issue, and help-wanted to help you get started.
- Read our Contributing Guide
- Find an issue or propose a new feature
- Fork the repository
- Create a feature branch (
git checkout -b feature/amazing-algorithm) - Commit your changes (
git commit -m 'Add QuickSort visualization') - Push to your branch (
git push origin feature/amazing-algorithm) - Open a Pull Request
Looking to contribute but not sure where to start? Check out these beginner-friendly areas:
- 🎨 Add new algorithm visualizations (Merge Sort, Quick Sort, etc.) - See guide

Vizit uses GitHub Actions for continuous integration, automated testing, security scanning, and deployment. Our CI/CD pipeline ensures code quality, security, and smooth releases.
Runs comprehensive checks on all pull requests and pushes to main:
- Lint - ESLint checks for code quality and style consistency
- Type Check - TypeScript compiler validation
- Build - Next.js production build verification
- Caching - npm dependencies cached for faster runs
Triggers: PRs and pushes to main
Enforces consistent code formatting across the codebase:
- Validates ESLint rules on all TypeScript/JavaScript files
- Automatically comments on PRs with formatting issues
- Helps maintain clean, readable code
Triggers: Pull requests modifying .ts, .tsx, .js, .jsx, .mjs, or .css files
Automatically deploys to Vercel after successful CI:
- Builds production-ready Next.js application
- Deploys to Vercel hosting platform
- Creates deployment summary with commit details
- Only runs when CI passes successfully
Triggers: Pushes to main after CI completion
