Detailed Introduction
drawio-desktop is an Electron-based desktop application that wraps the core draw.io editor, providing a powerful, fully offline diagramming tool. It supports flowcharts, UML, network diagrams, wireframes, and many other diagram types. The app is completely isolated from the internet (except for update checks) — no diagram data is ever sent externally, and no analytics are collected. It is released under the Apache 2.0 license, free for any purpose. Built binaries are available for Windows, macOS, and Linux. The project has a large community (over 61k stars) and is actively maintained by JGraph. Note that the project does not accept external contributions due to high complexity.
Troubleshooting & FAQ (2)
TroubleshootingWhy does draw.io desktop not show update notifications or prompts after selecting 'Search for updates'?
This was a bug in draw.io desktop version 30.0.0, where the update check did not display available updates and the app updated silently on exit without asking. Upgrade to version 30.0.1 or later to restore proper update notifications and prompts. You can download the latest package from the official website. After updating, the 'Search for updates' menu will show a prompt when a new version is available, allowing you to accept or decline the update.
TroubleshootingWhy does draw.io CLI export invalid PNG files with 'zTXt: CRC error'?
This is a known bug in draw.io CLI versions 29.7.1 to 30.0.0. The CLI export creates corrupted PNGs when embedding the diagram. A workaround is to use the desktop application's GUI to export as PNG with embedded diagram instead. Track issue #2425 for a permanent fix.
