PlantUML Diagrams & Charts for Confluence
Free PlantUML for Confluence: write diagrams as code, preview live, and keep them in sync with GitHub, GitLab or Bitbucket

What PlantUML Diagrams & Charts does
Keep diagrams as code inside Confluence Cloud. Write PlantUML, see a live preview side by side, and publish — no drawing tools, no exported PNGs.

Add the PlantUML macro
Insert it on any page, then start from a template, import a .puml file from GitHub, GitLab or Bitbucket, or ask Rovo for the code.
