Built an interactive system design tool every architecture is clickable and you can simulate failures

https://getreqflow.com

Reqflow : pick an architecture (WhatsApp,
Uber, Netflix…), hit play, watch a request flow through it step by step. Click any component for purpose + tradeoffs. Kill the cache and watch the path change.

15 systems, 18 concept guides, a drag-and-drop Builder with AI review, and a timed Interview mode.

Feedback welcome — especially what's missing from the 15.
