Startup Stash is one of the world's largest online directory of tools and resources for startups
Free, open-source diagram editor, now back under its original name, draw.io.
Yes, under a different name. diagrams.net now redirects to drawio.com, and the same free diagram editor is called draw.io again. It needs no sign-up and its source code is Apache 2.0 licensed.
You can draw in the browser or install the desktop app, which has builds for Windows, macOS and Linux (version 32.6.10 came out in early Nov 2026). Diagrams save to Google Drive, OneDrive, SharePoint, GitHub or your own device, and draw.io says it does not store your diagram data on its servers. It also works inside Confluence and Jira, Google Docs and Slides, Microsoft Teams, VS Code and Notion. The company is listed as draw.io Ltd and draw.io AG.
Bottom line: bookmark drawio.com instead of diagrams.net. For flowcharts, network and architecture diagrams it is still a strong free choice. Pick a paid tool like Creately only if you need diagrams fed by live data or built-in team admin.
Open the editor and start drawing. No sign-up, no paid tier for features like SSO.
Save to Google Drive, OneDrive, SharePoint, GitHub or a local file. draw.io says it does not store your data.
Integrations for Confluence and Jira, Google Docs and Slides, Microsoft Teams, VS Code and a Notion Chrome extension.
An offline app for Windows, macOS and Linux, with command-line export to PNG, SVG, PDF and more.
