Hi Product Hunt 👋

I used to design systems on paper — sketch, erase, redraw, repeat. The ideas were clear, but the diagrams were slow and never matched what was in my head.

So I wondered: what if diagrams were created as easily as thinking in code?

That’s how LLD Visualizer was born.

You can either write simple UML-style text or use a clean GUI to create classes and relationships — and the diagram appears instantly. No dragging mess, no alignment headaches.

Just create → see → iterate.

It’s great for LLD interview practice and for anyone who thinks visually but hates fighting diagram tools.

If you’ve ever stared at a blank canvas wondering where to start, this is for you.
