STOA Verdict	Beauty Diagram is a strong fit for small dev shops, technical consultants, or agencies that already write Mermaid or PlantUML diagrams and want them to look polished fast. You get real time savings — no manual Figma cleanup — and the AI generation feature is a genuine bonus. That said, if your team doesn't already use diagram-as-code, the learning curve makes this a tough sell compared to drag-and-drop tools.
