Hey Product Hunt 👋
I'm Levi. Mermaid and PlantUML are great for *writing* diagrams fast,
but the moment I drop one into Notion, GitHub, or Confluence, two things
happen: the layout breaks in weird ways, or it renders fine but looks
so plain it clashes with the rest of my slide deck.
So I'd end up redrawing in Figma, or screenshotting and hoping nobody
zooms in. Both terrible.
Beauty Diagram fixes this. Paste your Mermaid or PlantUML code, hit
beautify, pick a theme that matches your doc or deck — done. For
higher-stakes moments (kickoffs, demos, exec reviews), there's also
animated playback you can export as a GIF.
Same engine ships as a web editor, a `bd` CLI, and an HTTP API, so it
fits whether you're polishing one diagram or wiring it into CI.
Free tier for everyday use, paid for teams and higher limits.
Two things I'd love feedback on:
1. Which doc tool's rendering frustrates you most? (Notion / GitHub / Confluence / other)
2. Which theme would you actually pick for a real document?
I'll be in the thread all day 🙏
