System Design Atlas - Interactive architecture diagrams for 15 classic system design problems
Show HN: An atlas of system designs with interactive architecture diagrams
System Design Atlas is a free web resource that presents 15 worked system design problems, ranked by how often they appear in interviews. Each design includes an interactive architecture diagram and clear explanations of key concepts like fan-out, caching, sharding, and idempotency. From Twitter's feed to Google Docs, it covers the real-world challenges engineers face. Whether you're preparing for interviews or building scalable systems, this atlas helps you understand the trade-offs and patterns that matter. Visit the site to explore the diagrams and level up your system design skills.
A design that only works for the median user fails — fan-out cost is bimodal and the code path has to split.

Hey! This is cool, and actually in the same spirit of my own tool. Not sure if you'd be interested in combining your vision of a repository of architecture models, with my platform (blueprintr.io)?
Seems like a match made in heaven :)

Checked it out and I must say this is really incredible work. Wow!

Really nice! It’s also a good reminder that there is always more to discover. Even when you think you know it all.
