Daily coding challenge — one new problem every day across 3 difficulty levels (easy/medium/hard), so you can pick what fits your level. Think Wordle, but you write code.
- New problems daily, auto-generated and curated
- 20 languages supported (Python, C++, Java, Go, Rust, and even Brainfuck lol)
- Streak tracking to build a daily habit
- Weekly / all-time leaderboards
- Runtime-based ranking (see how fast your solution is vs others)
- Public/private solutions
- Achievement badges
