Hey Product Hunt 👋 I'm Prabhat, a 2024 grad from Bangalore.
System design was the hardest part of my interview prep. Everything was static boxes and arrows, and none of it showed what actually happens when you tap Send.
So I built sd-for-rookies: you watch one real request travel through ChatGPT, Zepto, WhatsApp and Uber, step by step, with a voice explaining each hop. Then you see the same story one level down as an API sequence diagram. There are also 10 side-by-side comparisons, like Monolith vs Microservices, TCP vs UDP and REST vs GraphQL.
It's free, needs no sign-up, and works on a phone.
Two things I'd love feedback on: which system should I build next, and was any comparison confusing?
