Before I switched to Obsidian for note taking, I'd been using UMLet (for some 20 years!) for all my UML needs. Its syntax for sequence diagrams is similar to Mermaid's. But now that I'm using Obsidian, I've switched to Mermaid. I see some people mentioning PlantUML, but I rather dislike that it required a rendering service last I tried to tinker with it. Mermaid does not.
