Mermaid Cheat Sheet

This page summarizes the projects mentioned and recommended in the original post on

Our great sponsors
  • Klotho - AWS Cloud-aware infrastructure-from-code toolbox [NEW]
  • Appwrite - The Open Source Firebase alternative introduces iOS support
  • Sonar - Write Clean JavaScript Code. Always.
  • InfluxDB - Access the most powerful time series database as a service
  • mermaid

    Generation of diagrams like flowcharts or sequence diagrams from text in a similar manner as markdown

    Individual diagrams have their grammar in a .jison file.


    A single grammar to support all the different use cases would be challenging. But we did have some plans to introduce guidelines to make different diagram syntaxes more consistent.

  • quickadd

    Parse natural language time and date expressions in python (by Acreom)

    there's also D2 which is worth exploring.

    if anyone wants to try out mermaid in their own .md knowledge base we've built a smooth editor experience in (no account required).

  • Klotho

    AWS Cloud-aware infrastructure-from-code toolbox [NEW]. Build cloud backends with Infrastructure-from-Code (IfC), a revolutionary technique for generating and updating cloud infrastructure. Try IfC with AWS and Klotho now (Now open-source)

  • text-to-diagram-site

    Compare syntax, layouts, outputs between languages for generating diagrams with text.

    I think Mermaid is better than PlantUML to write something quickly.

    But D2 looks very promising. I like the simpler and more intuitive syntax.

  • fusionauth-site

    Website and documentation for FusionAuth

    I actually have much more experience with plantuml (we actually have a plugin which generates diagrams for our jekyll/asciidoc docs site: ), but I have recently started using mermaid for a project and like it so far.

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
