About ZenUML
ZenUML is a diagram-as-code product family operated by P&D Vision Pty Ltd, an Australian company. It renders concise, Markdown-inspired text definitions into sequence diagrams and other UML diagrams.
Where ZenUML runs
ZenUML ships across several platforms so a diagram written once can be used wherever the team already works:
- ZenUML Diagrams for Confluence — Atlassian Marketplace app for Confluence Cloud
- ZenUML Online Editor — a web app
- Chrome extension
- JetBrains plugin
- Visual Studio Code plugin
- Desktop apps for Mac and Windows
Origins
ZenUML began as a diagramming tool built inside a finance-industry project, and that background shaped an early product decision: rendering had to be trustworthy for regulated environments.
Privacy by design
Diagrams render entirely in your browser — no diagram content is sent to a ZenUML server to be drawn, including when exporting an image. See the Privacy Policy for the full detail on what data we do collect (usage analytics, cookies) and how it's used.
