Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

draw.io is a browser-based and desktop diagramming application for creating technical, business, software, infrastructure, and process diagrams. It suits teams and individuals that need broad diagram coverage without a core editor charge, including flowcharts, UML diagrams, org charts, mind maps, network diagrams, floor plans, infographics, Kanban boards, BPMN diagrams, ER diagrams, Gantt charts, and timelines. The editor is available on the web, Windows, macOS, Linux, and as a Chrome Extension, with an offline desktop application for the three desktop operating systems.

Its strongest fit is cross-platform work connected to existing storage and productivity systems. Integrations include Google Drive, Microsoft OneDrive, Dropbox, GitHub, GitLab, Atlassian Confluence, Atlassian Jira, Notion, Microsoft applications, and VS Code. Supported storage and integrations can provide real-time collaborative editing with shared cursors, while revision history and restore support are available when diagrams are stored on supported platforms. The editor also supports imports from draw.io, XML, Gliffy, VSDX, Lucidchart, PNG, SVG, and JPEG, plus exports to PNG, SVG, JPEG, WebP, PDF, HTML, XML, JSON, and URL formats.

The standout value is breadth without narrowing users to one diagram type or workflow. Shape libraries, templates, custom shapes, layers, tags, links, tooltips, metadata, automatic layouts, and diagram generation from Mermaid code, CSV data, SQL code, and text give teams multiple ways to create and maintain diagrams. The core editor is free forever and Apache 2.0 licensed. It is a strong choice for teams needing flexible, open-source diagramming across platforms; teams seeking a separately tiered paid editor should consider a product built around that model instead.
