Free and open-source diagram editor
diagrams.net (previously draw.io[2][3]) is a cross-platform graph drawing software developed in HTML5 and JavaScript.[4] Its interface can be used to create diagrams such as flowcharts, wireframes, UML diagrams, organizational charts, and network diagrams.[5]
diagrams.net is available as an online web app, and as an offline desktop application for Linux, macOS, and Windows.[5] 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.[5][6] Supported storage and export formats to download include PNG, JPEG, SVG, and PDF.[6]
It also integrates with cloud services for storage including Dropbox, OneDrive, Google Drive, GitHub, and GitLab.com.[5][6][7]
It is also available as plugin to embed the web app in platforms such as NextCloud, MediaWiki, Notion, Atlassian Confluence, and Jira.[8][9]
It has been described by tech reviewers such as TechRadar and PCMag as an alternative to Lucidchart, Microsoft Visio, and SmartDraw.[10][11][12][4][13][14]
