Top free DSA repos circulating
A popular thread is resurging GitHub staples for interview prep — Coding Interview University (337k stars), NeetCode collections, Algorithms repos, and labuladong’s pattern guides — as a consolidated self‑study path for FAANG prep. The roundup highlights these free resources as an end‑to‑end CS curriculum for DSA, system design, OS and networking. (x.com)
The thread’s single most‑starred entry, jwasham/coding‑interview‑university, shows about 340,000 stars and 81,800 forks on GitHub. (github.com) Donne Martin’s system‑design‑primer registers roughly 341,000 stars and 55,100 forks and explicitly includes Anki flashcard decks and multi‑language translations for system design study. (github.com) Labuladong’s flagship repo (fucking‑algorithm) has about 133,000 stars and points to a 500+ problem library and structured study plans on labuladong.online. (github.com) TheAlgorithms organization’s Python repository lists roughly 217,776 stars and maintains broad, language‑agnostic algorithm implementations used by learners and interview prep contributors. (githublb.vercel.app) NeetCode’s GitHub mirror (neetcode‑gh/leetcode) shows ~6,300 stars, supports solution code across a dozen+ languages, and contains nearly 9,800 commits documenting ongoing updates. (github.com) Each project explicitly maps to different parts of an end‑to‑end curriculum: Coding Interview University lays out algorithmic complexity and a CS study plan, system‑design‑primer organizes large‑scale design patterns and interview questions, labuladong delivers pattern‑based problem templates, and NeetCode exposes searchable, multi‑language solutions tied to a curated problem list. (github.com) All four repositories show recent maintenance activity (system‑design‑primer updated within the past two weeks, NeetCode repo updated last week, and labuladong branches restructured in the last month), indicating active community upkeep rather than archival status.
