Diagrams that don't look like they were auto-generated
Beauty Diagram makes your Mermaid and PlantUML diagrams beautiful. Pick from curated themes, animate the flow, and export as SVG, PNG, or GIF. Use the web editor, CLI, or API to drop diagrams straight into docs, PRs, and presentations.
Pro plan allows import of .drawio and .xml files, which Beauty Diagram parses into Mermaid source, beautifies, and keeps editable—enabling teams to move from canvas-based to code-based diagram workflows.
Beauty Diagram re-lays out flowcharts with orthogonal routing, applies modern typography and themes, and exports clean SVG/PNG in one click—transforming default renders into presentation-ready visuals without rewriting source code.
AI Generate and AI Refine features turn prompts into Mermaid/PlantUML source or improve existing diagrams for clarity and structure—reducing manual syntax writing and enabling faster iteration on diagram content.
Beauty Diagram exports shareable SVG image URLs that load on every view without re-export—allowing diagrams to stay in sync with source repositories and documentation without manual refresh cycles.
Nine built-in themes (modern, atelier, atlas, obsidian, etc.) and five animation styles swap instantly across all diagrams using the same source code—ensuring visual consistency across decks, docs, and dark-mode environments.
