I built ddash — a diagram tool that lives entirely in the URL (comes with a Claude Code skill)

By SolarSurfer919 · DISCUSSION · About Claude Code

I built ddash, a free Mermaid diagram tool where the entire diagram is compressed into the URL hash. No backend, no accounts, no storage — just share the link and the diagram is right there. I built it with Claude Code and it ships with a SKILL.md file so Claude Code can generate and open diagrams directly during a conversation. You type something like /diagram the auth flow and it explores your code, builds a Mermaid diagram, and opens it in ddash. What it does: - Write Mermaid syntax on the left, see the rendered diagram on the right - Everything is stored in the URL — share it, bookmark it, paste it in a PR - Comes with a Claude Code skill for one-command installation - Free, no signup Try it: https://ddash.zweibel-cocaine.com/

NeonGamer522: Super useful - would be nice to write the mermaid syntax with AI directly in the platform
