About diagram editors

Hi all,  I have been using MermaidJS (Javascript, MIT license), mainly because I have used in other projects and it has web-based editor and can save data in link, but looks like the .puml (PlantUML? Java, GPL3) editor has similar functionality as well.  The data formats are slightly different, so it might make sense to settle on one of them. Also, PlantUML link seems to be a bit shorter, I guess they compress the data.. (which makes it harder to decode without their tool, though).
For reference, MermaidJS link:
