Show HN: I made system design easy

https://www.robustdesign.io/
3•greatjosh•50m ago
Hi HN, I made system design easy by making an interactive platform to help you simulate and test your design!

While learning system design, I noticed that there weren't any tools around that helps you test and simulate your systems. It's like writing code without being able to actually run your code. So I created a platform that gives you the ability to run and test your designs.

I've also included a gallery of some of the most common system design patterns which I plan on adding more to it.

It's completely free to sign up if you want to do some testing.

I built it with React/Next.js for the frontend and Flask/Firebase for the backend

Would love your feedback on it! What other components would be useful? What system design patterns should I add as templates?
