Mermaid is an open-source JavaScript-based diagramming tool that renders Markdown-inspired text definitions to create diagrams dynamically. It allows developers and technical writers to create visualizations using simple text syntax rather than graphical interfaces.
Mermaid supports multiple diagram types including flowcharts, sequence diagrams, class diagrams, state diagrams, Gantt charts, pie charts, entity-relationship diagrams, and more. It also supports mathematical expressions and theme customization.
Yes, Mermaid is open-source software available for free through mermaid.live. There is also MermaidChart, a premium visual editor offering additional features for teams and enterprise users.
Mermaid is ideal for developers, technical writers, and teams who need to create diagrams programmatically. It is particularly valuable for documentation, software architecture planning, project management, and anyone who prefers code-based approaches over traditional drawing tools.
