System‑design resources trending on social
A popular YouTube channel and a comprehensive GitHub repo are circulating as go‑to resources for system design topics — API design, sharding, caching, concurrency and rate limiting shared shared. The two links are being recommended together by engineers prepping for Google/Meta/Amazon style interviews.
The GitHub guide donnemartin/system-design-primer currently lists about 339k stars and ~54.9k forks on GitHub. (github.com) The primer’s README shows multi‑language translations and active maintenance with dozens of open pull requests, reflecting ongoing edits to sections like caching and capacity planning. (github.com) Gaurav Sen’s system‑design YouTube channel reports roughly 723k subscribers and a System Design playlist that totals about 26 videos and ~6.8M aggregated views. (youtube.com) That playlist explicitly covers API design, database sharding, caching, concurrency and rate limiting through standalone videos such as “What is an API and how do you design it?” and “Database Sharding,” which each have six‑ to seven‑figure view counts. (youtube.com) Community curation lists used by interview candidates are already linking the two: public repos and resource lists (e.g., “Resources for Senior Software Engineer”) reference Gaurav Sen videos alongside the System Design Primer as a packaged study set. (github.com) Recent signals show both resources are live and being updated—donnemartin/system-design-primer recorded commits in the last week and Gaurav Sen’s playlist was refreshed with course updates in early 2026—explaining why engineers prepping FAANG‑style interviews are circulating them together.
