About Draw.io
Draw.io — officially diagrams.net — is a free diagram editor for flowcharts, UML, network diagrams, floor plans, and org charts, available as a web app at app.diagrams.net, a desktop app, and integrations for Google Drive, Confluence, and Jira. Files save in standard formats to your own storage, so there is no lock-in and no account requirement for the core editor. It is less pretty than newer whiteboards but unmatched for technical diagramming depth at zero cost, which is why it remains a default in engineering teams. The web and desktop apps are free; paid versions exist mainly as Atlassian marketplace apps.
