diagrams.net (previously draw.io) is a cross-platform graph drawing software application developed in HTML5 and JavaScript. Its interface can be used to create diagrams such as flowcharts, wireframes, UML diagrams, organizational charts, and network diagrams.
diagrams.net is available as an online web app, and as an offline desktop application for Linux, macOS, and Windows. Its offline application is built using the Electron framework. The web app does not require online login or registration and can open from and save to the local hard drive. Supported storage and export formats to download include PNG, JPEG, SVG, and PDF.
It also integrates with cloud services for storage including Dropbox, OneDrive, Google Drive, GitHub, and GitLab.com.
It is also available as plugin to embed the web app in platforms such as NextCloud, MediaWiki, Notion, Atlassian Confluence, and Jira.
It has been described by tech reviewers such as TechRadar and PCMag as an alternative to Lucidchart, Microsoft Visio, and SmartDraw.
