The desktop apps and the standalone Android app include the server, so you can install and start right away. You can also deploy it to a NAS or server and use it in any browser on phones, tablets and computers.
The current Windows installers are unsigned. The project is applying to SignPath Foundation for code signing. If SmartScreen appears, choose “Run anyway”. Windows 11 on ARM runs the x64 build through built-in emulation.
The app is not signed by Apple. If macOS says it is damaged or can’t be opened, move it to Applications and run xattr -cr /Applications/WrongNotebook.app and codesign --force --deep --sign - /Applications/WrongNotebook.app in Terminal, then open it.

Want new features early? Download a preview build (pre-release) from GitHub Releases. Fresh installs have no default account: the desktop and standalone Android apps open the admin setup page on first launch, fnOS asks for the admin email and password in the install wizard, and Docker and npm print a one-time setup link in the startup log.
