Nuit

What is Nuit?

Nuit is a Safari extension for macOS that brings dark mode to websites while you browse in Safari. It is designed for people who prefer a darker reading experience at night or want to reduce the brightness of web pages during long browsing sessions. The app can apply a dark theme across sites, let you tune visual settings such as brightness, contrast, and grayscale, and save preferences for individual websites. It also includes theme customization and keyboard shortcut support for quicker control while browsing. Nuit integrates with Safari rather than replacing your browser, so it fits into a normal Mac web workflow for reading, research, and everyday browsing.

Key features

• Apply dark mode to websites in Safari
• Adjust brightness, contrast, and grayscale for page rendering
• Save different dark mode settings for individual websites
• Choose from built-in themes or create a custom look
• Use keyboard shortcuts to toggle dark mode quickly
• Detect sites with native dark mode to reduce visual conflicts
• Sync settings with iCloud across supported devices

Safety overview

Status: Safe

Nuit is a legitimate Safari extension for changing the appearance of websites. It works within Safari and stores its settings on your device, which is normal for this kind of browser utility. Because it can modify how pages are displayed, some websites may look different than intended or need per-site adjustments. If a page becomes hard to read or behaves oddly, turn the extension off for that site and keep Safari and the extension updated.

Recommendation: Keep Nuit if you use Safari and want dark mode on websites that do not offer it natively. If you no longer need forced dark mode, you can remove the app or disable the Safari extension without affecting macOS beyond losing its webpage appearance controls.
