  • Integrates with IDEs, Git, documentation tools, Docker, and APIs
Cons
  • The $6 Modeler plan is based on a single seat
  • Advanced capabilities require higher-priced plans
  • Its breadth may exceed the needs of simple diagramming projects
  • Built-in real-time multi-user collaboration is not a core feature
  • Version history is not built into the diagramming workflow
  • Text-first authoring is less visual than drag-and-drop editing
