Beauty Diagram turns Mermaid and PlantUML into presentation-ready diagrams.
Beauty Diagram is a diagram beautifier for Mermaid, PlantUML, and draw.io workflows that focuses on making code-generated diagrams look intentional instead of default. It offers curated themes, animated SVG/GIF previews, and export to SVG, PNG, and GIF through a web editor, CLI, and API, so teams can move the same source from docs to PRs to presentations without redrawing it in Figma.
// ANALYSIS
Hot take: this is a sharp wedge product because it solves the ugly-last-mile problem for text-based diagrams instead of trying to replace Mermaid or PlantUML.
- –Strong fit for engineering teams that already author diagrams in code and just want better output.
- –The theme and animation layer is the real differentiator; that is what makes it shareable in slides and docs.
- –CLI and API support make it more than a designer-only web app, which should help adoption in CI and documentation pipelines.
- –The main risk is overlap with existing diagram tools unless the beautification quality is clearly better than native renderers.
