Mermaid Live Editor
Preview flowcharts, sequence diagrams, and other diagrams from Mermaid syntax.
What it is
Mermaid Live Editor is Mermaid’s open-source browser editor. Enter Mermaid syntax to preview a diagram in the same workspace and adjust the code or configuration.
Why it is selected
Text-based diagrams make it possible to change nodes or flows without redrawing the whole canvas. The editor needs no local setup, so it works well for trying the syntax before adding it to documentation.
Who it suits
Developers and technical writers maintaining flowcharts, sequence diagrams, or architecture notes in documentation.
Useful for
- Prototyping flowcharts and sequence diagrams
- Adjusting Mermaid syntax and checking the result immediately
Usage note
In this review, loading the built-in Flowchart example produced the corresponding diagram in the preview. The official project also lists SVG export and share links; those features were not tested individually.
