How They Scaled
Real "how we scaled" stories from top engineering teams
How They Scaled collects the best "how we scaled" write-ups from engineering blogs into one searchable place. Today it has 54 real case studies from 22 companies, including Slack, Discord, GitHub, Figma and OpenAI. You can filter by stack (Postgres, MySQL, Redis, Kafka...), technique (sharding, caching, read replicas, queues) or company. Scale numbers appear only when the original article states them, so nothing is made up.
New posts are pulled from 24+ engineering blogs and added every week. A free weekly newsletter sends you the best new write-ups. It's built for backend engineers, SREs and anyone studying for system design interviews who wants real-world examples instead of theory.
