★ 43k

The diagramming workhorse — flowcharts, architecture diagrams, UML — runs fully client-side or as your own container.

draw.io does the job of Lucidchart, self-hosted. It is Apache-2.0-licensed, so you can do essentially what you like with it, and it installs in about one command. Lucidchart bills $9/mo for it. 43k stars on GitHub.
