A real-time collaborative development environment that makes coding together as easy as sharing a document. Think VS Code, but multiplayer.

We saw coding classes relying on tools meant for writing essays—not code. While they got the job done, they weren’t built for real-time programming. So we created CodeCafé: a seamless, browser-based coding environment designed for true collaboration, making it easier to teach, learn, and build together.
- Real Dev Environment: VS Code-like experience (Monaco Editor) with syntax highlighting, autocomplete, and error detection
- True Collaboration: Multiple users can code together in real-time
- Run Your Code: Execute code directly in the browser using Piston API
- Language Support: Python, Java, C++, JavaScript, and more
- No Setup Required: Everything runs in the browser
- Frontend: React + TypeScript
- Backend: Java Spring Boot
- Real-time: WebSocket
- Session Management: Redis
- Code Execution: Piston API
