"Hey everyone! 👋 We built SystemDecoder because we were frustrated with how isolated system design learning felt.
We'd memorize patterns for interviews, design something in a whiteboard, but never see what actually happens when load hits your architecture—where it breaks, why, and what to do about it.
So we built a visual canvas where you can:
Drag-and-drop your system (API Gateway, DBs, caches, queues, CDN—the works)
Run realistic load simulations and watch latency/throughput/failures in real-time
Inject chaos events to test resilience
Learn the "why" behind each design decision through interactive modules
The core insight: system design shouldn't be theoretical. It should be interactive, visual, and immediate.
We started with students prepping for tech interviews, but learned that full-stack engineers and teams doing architecture discussions found it invaluable too.
We'd love to hear what you think! If you've struggled with system design, what would make the learning click for you? Any component types or scenarios you'd want to simulate?
Try it out and let us know—your feedback shapes what we build next. 🚀"
