draw.io (diagrams.net): a versatile, open-source diagramming tool

draw.io, also known as diagrams.net, is a browser-based diagramming application aimed at a wide range of use cases including flowcharts, network diagrams, UML, wireframes and organizational charts. It combines an accessible drag-and-drop interface with a comprehensive shape and template library, multiple deployment options and straightforward export capabilities, making it suitable for individual contributors, educators and technical teams.

Core strengths

• Open source and free: the core application is free to use, with source-available code and self-hosting options for organizations that require on-premises control.
• Flexible deployment: the web app runs in modern browsers without requiring an account. Native desktop builds are available for Windows, macOS and Linux, and a mobile app for Android supports touch and stylus input for on-the-go edits.
• Cloud and integration options: diagrams can be saved to Google Drive, OneDrive and Dropbox. Embedding and linking support for platforms such as Confluence and Jira helps integrate diagrams into documentation and project workflows.
• Extensive templates and shapes: built-in libraries cover BPMN, UML, network diagrams, mind maps and more, while custom shapes and stencil import enable standardized diagram components.

Key features and functionality

• Drag-and-drop editor with snapping, alignment guides, grid controls and keyboard shortcuts for precise layouts.
• Reusable shape libraries and support for custom shapes and templates to maintain consistency across diagrams.
• Collaboration via shared cloud files and built-in version history for restoring prior states and tracking changes.
• Multiple export formats including PNG, JPG, SVG, PDF and XML for sharing, printing and archival purposes.
• Options for local file saving, offline desktop use and self-hosted deployments to address privacy and compliance requirements.

Usability and practical applications

The interface balances approachability for newcomers with controls that experienced users expect: snapping and alignment tools simplify tidy layouts, while precision controls and XML export support technical handoffs. The template catalog accelerates common diagram types for product teams, systems architects and educators. Desktop and mobile builds extend functionality beyond the browser, enabling offline editing and stylus input on compatible Android devices.

Limitations

• Advanced live-collaboration features such as real-time cursors and in-app presence are less developed than some subscription-based competitors.
• Some enterprise-level features require additional configuration or a self-hosted setup to meet stricter governance or integration needs.

Getting started

1. Open the web app at diagrams.net or install a native desktop build for offline use; Android users can install the app from Google Play for mobile editing.
2. Select a template or start from a blank canvas, then drag shapes from the sidebar and connect them with smart connectors.
3. Use alignment tools, grids and snapping to tidy the layout, then save to cloud storage or locally and export in the desired format.
