Based, PaperDraw.dev – A System Design Simulator works in show hn launch.

Profile

Hi HNI recently built PaperDraw.dev, a browser-based system design simulator aimed at helping engineers practice real system design thinking, not just draw static diagrams.Most tools today are diagramming tools. They help you draw boxes and arrows, but they don’t help you answer questions like:• What happens when traffic spikes 10×? • Where does the bottleneck appear? • How does latency propagate across services? • What breaks first under load?That’s the gap I wanted to solve.What it doesPaperDraw is not just a whiteboard — it’s a simulation engine for system design.You can:Drag and drop components like LB, Cache, DB, Queues, ServicesConnect them visuallyConfigure throughput, latency, capaci

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Directory data places it at the Show HN launch stage.
