About
Beauty Diagram is an online editor for Mermaid, PlantUML, and draw.io diagrams that post-processes renders to produce cleaner, more professional-looking outputs. It offers re-layout with orthogonal routing, multiple modern themes, animated SVGs, and one-click export to SVG or PNG. It also supports AI-assisted diagram generation and is available as a plugin for Obsidian, VS Code, and CLI.
Problem
Default Mermaid and PlantUML renderers produce functional but visually plain diagrams that look unprofessional in presentations, documentation, and README files.
For
Software developers, technical writers, and engineers who write diagrams as code
How it works
Users paste their Mermaid or PlantUML source into the editor, which re-lays out the diagram with orthogonal routing, applies modern themes and typography, and exports polished SVG or PNG in under 400ms.
