Show HN: Free Mermaid Diagram Editor (moxiedocs.com)

51 points by ghosts_ 2mo ago ↗ HN

I've been slowly adding some new free tools to Moxie Docs (partly for SEO, partly to illustrate some of our feature sets before any commitment) for some reason this mermaid editor one blew up on Google rankings so I figured I'd share in case people find it useful! We also have ADR, AGENTS.md, LLMs, and a few other free tools.

Probably because the official editor sucks after paywalling features and steering you into signing up.

Handy.

I've been (very loosely) trying to get AI to generate diagrams for a while, and even Copilot can't get Visio's file format correct enough to allow Visio to open it successfully.

This is a nice clean interface I can just paste attempts into. Thank you!

I created https://smalldocs.org to help with this. After installing you can tell your agent to "sdoc me a mermaid diagram of X flow" or "sdoc me a visual architecture of this repo" or something, and it handles it nicely (imo!).

Here is the mermaid diagram gallery: https://smalldocs.org/s/PpArByXuNBA5kGS1JVMUW6#k=uTqNRLqzz_T...

Yeah the main product I'm working on (Moxie Docs) has AI generation of mermaid diagrams, I find that it works __well enough__ but I needed some strong guardrails, quality checks, and templating to make sure it doesn't generate broken diagrams (or useless ones). First few iterations it would create a diagram for everything and it was a bit zealous on when it decided diagrams would be useful.

Question for mermaid users out there. I have not used mermaid more than just superficially looking at it but it looks to me like a re-implementation of graphviz? Which has been around forever. Is there something it does that makes it more appealing?

I am not knocking this Free Mermaid Diagram Editor either. Seems decent. But, similarly, edotor has been around forever.

Shout out to Kroki, which offers Mermaid and many other text-based diagramming formats.

Thanks for dropping this here. I have been frustrated for quite some time. I blindly followed the advice to learn some mermaid. Then I discovered that the ecosystem absolutely sucks.

The only problem with mermaid that GitHub UI renders it poorly. Large diagrams very difficult to view. Any solution for that?
