Favorite UML Modeling Tool?


Hi HN. What's your current favorite browser-based UML modeling tool? Is there an industry standard standout at this point?

Also, while I hear the "browser based" in your question, be aware there is a plugin for the JetBrains tools that gives instant feedback, which can speed up the "development cycle" for PlantUML diagrams: https://plugins.jetbrains.com/plugin/7017-plantuml-integrati... and https://github.com/esteinberg/plantuml4idea#readme

Regarding mermaidjs, I draw attention to the fact that GitLab's markdown language supports it, which is incredibly handy in MR descriptions or wiki pages: https://docs.gitlab.com/ee/user/markdown.html#mermaid

Are you looking for a textual UML tool (https://modeling-languages.com/text-uml-tools-complete-list/) to "write" your UML models and then easily render them in your browser?

Or for a graphical online UML editor (https://modeling-languages.com/web-based-modeling-tools-uml-...)?

If the former, then plantUML is my favourite. If the latter, there quite a few options but one that's easy and fast is http://www.umletino.com/

it can be browser-based but there are many integrations, for example it's trivial to have it rendered as image in markdown files
