Summary

draw.io is a free, open-source diagramming tool for making visual layouts ranging from flow charts and mind maps to network diagrams, floor plans, UML, BPMN, and C4 models. It is available on the web, Windows, macOS, Linux, iOS, and Android, with real-time collaboration and cross-platform editing of diagram files. Users can choose their own storage or save locally with the desktop app, and draw.io says it cannot access their data. No sign-up or credit card is required to start. Diagrams can remain editable or be exported as SVG, PNG, or PDF; imports include draw.io, XML, Gliffy, VSDX, Lucidchart, PNG, SVG, and JPEG. The tool also offers version history and integrations with Google, Microsoft, Atlassian, GitHub, VS Code, Notion, and Chrome. Interactive diagrams can be embedded in documents, wikis, or applications. Support is available through GitHub Discussions and Stack Overflow.
