- User selects a topic and language.
- A random question is pulled from the database based on the selected topic.
- The user writes code in the in-browser editor.
- Code is sent to the backend and executed inside a Docker container for that language.
- Output or errors are returned in real time.
- Docker-based isolated code execution
- AI-based hint system and solution feedback
- Leaderboards and community challenges
- Light/Dark mode and editor theming
- Mobile-first responsive design
- Time-based coding contests
