Commit turns coding interview prep into a habit, not a chore. Swipe through flashcards the way you'd swipe through anything else — right when you know it, left when you don't (it comes back later). Every card has a real interview-style question, a full written explanation, and syntax-highlighted code where it matters. 30 TOPICS, 7,200 CARDS Languages: Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, Swift, Ruby, Kotlin, C Data & Query: SQL, MySQL, PostgreSQL, MongoDB, Redis, GraphQL Web & Frameworks: React, Node.js, Spring Boot, Django, ASP.NET Core Systems: System Design, Docker, Kubernetes, Git, Linux/Sysadmin, AWS Cloud Fundamentals Security: OWASP/AppSec Every topic has 240 cards split evenly across Beginner, Intermediate, and Expert — so it grows with you instead of throwing senior-level questions at you on day one. HOW IT WORKS • Swipe right when you know it — the card moves on • Swipe left when you don't — it comes back later for review • Scroll any card for the full explanation, not just the answer • Tap code blocks and images to view them full-screen • Pick exactly which topics and difficulty levels show up in your feed • Track your daily streak and review your history Built for the 20 minutes between meetings, the commute, or the last thing before bed — pick it up, swipe through a few cards, put it down. No accounts, no setup, no pressure.
