How do you validate your system designs before writing code?

Hey Product Hunt community! 👋

Static architecture diagrams (looking at you, Visio and Miro) are great for documentation, but they always leave a massive blind spot: how does the data actually move when things get busy? We are Archi-Flow, and our whole goal is to turn static cloud architecture maps into living, breathing spaces with real-time live traffic simulations. The idea is to make system design reviews, debugging data flows, and engineering onboarding feel less like guesswork and more like watching a live map.

As we put the finishing touches on the launch, I’d love to know:

• How does your team currently bridge the gap between architectural design and real-world traffic reality?

• What’s the biggest bottleneck or "gotcha" you usually hit during system design reviews?

Would love to get your feedback and insights!
