Messaging Dark Mode
Dark Mode for Every Chat App
Guides for each app below — or install once and get the same dark theme on all of them.
Why Messaging Apps Need Dark Mode
Messaging is the most nighttime activity there is — and web versions of chat apps are inconsistent about dark themes. Discord's is dark by default, WhatsApp Web has one buried in settings, and switching between different dark greys across five apps is jarring.
One Dark Theme Across All Your Chats
Turn Off the Lights gives every messaging web app the same Night Mode theme — your background, text, and link colors everywhere. Schedule it for the evening and your chats go dark automatically as the sun goes down.
Open Source, Private, and Free — Always
Turn Off the Lights collects no personal data, displays no advertising, and charges nothing. The extension is fully open-source under the GNU General Public License Version 2 (GPLv2), with its complete source code available on GitHub for anyone to inspect. It has been in continuous development since 2009 and remains one of the most trusted browser extensions available, with millions of active users across all major browsers.
