Most system design resources show architectures as static diagrams. I wanted to build something where you can actually create an architecture, configure it, run it, and understand what happens inside the system. FlowFrame is an interactive system design simulator and learning environment built around that idea.

FlowFrame is an interactive system design simulator that helps developers visualize request flows through components like Load Balancers, API Gateways, Redis, and PostgreSQL. Explore distributed systems through simulations, inspect node states, step through request frames, and understand system behavior beyond static diagrams.
