Gliffy vs. Mermaid

Gliffy's diagramming applications make it easy to communicate and collaborate at the speed of your ideas. Whether you're using Gliffy in Confluence and Jira or jumping into our standalone diagramming tool, Gliffy Online, you'll find an intuitive way to draw diagrams. Drag and drop your way to professional-looking flowcharts, UML diagrams, entity-relationship diagrams, and more in just a few clicks. Plus, you can now build your diagrams using code with Mermaid js. Use a template to make a mind map or concept map while brainstorming.

Mermaid is a diagramming tool built on Mermaid.js, the open-source diagramming library. Diagrams are defined as text in Mermaid syntax, and the rendering engine determines the layout. When a process changes, updating the diagram is a text edit rather than a rebuild — the practical difference from drag-and-drop editors, where repositioning nodes is part of every revision.
