Built for
serious DSA practice

The Mission

frontendx DSA Inventory was built to solve a simple problem: finding good DSA practice problems shouldn't require jumping between 10 different platforms.

We've curated 38,000+ problems from 50+ platforms - LeetCode, Codeforces, AtCoder, GeeksforGeeks, CSES, Baekjoon, and beyond - organized them by topic, deduplicated them, and made everything searchable and filterable.

Open & Transparent

All problem data lives in plain CSV files. No black boxes. No proprietary APIs. Every problem is auditable, portable, and Git-friendly.
