Hey PH! 👋 I built SystemDesignBoard after bombing a system design interview because I spent the first 5 minutes fighting Excalidraw instead of thinking about the architecture. The idea: a whiteboard that already knows about services, databases, cloud providers, and trade-offs — so you can focus on the design, not the tooling. A few things I'm proud of: → The animated connectors actually show communication type (sync vs async vs stream) — not just arrows → Diagram-as-Code lets you type your architecture and it auto-lays out in seconds → The whole thing is keyboard-driven — place a node, connect it, annotate it without ever touching the mouse It's free during beta. Would love your feedback on what's missing or broken. 🙏 Try it: https://systemdesignboard.com/app
