Mermaid alternatives and similar tools

  • DrawThe.Net

    drawthe.net draws network diagrams dynamically from a text file describing the placement, layout and icons. Given a yaml file describing the hierarchy of the network and it's connections, a resulting diagram will be created.
  • Diagrams.net

    A.K.A. Draw.io. Easy to use Diagram UI with a plethora of templates.
