Dark Mode for Every Dev Tool
Guides for each tool below — built by a developer, open-source on GitHub.
Why Developers Need Dark Mode
You keep your editor dark, your terminal dark — then open GitHub or a Jira board and get blasted with white. That constant light-dark switching between tools is exactly what makes eyes tired by the end of the day. A consistent dark browser fixes it.
Open-Source and Hackable
Turn Off the Lights is GPLv2 open-source — the whole codebase is on GitHub if you want to inspect it. Night Mode applies before the page renders, so there's no flash of white, and per-site settings let you keep light mode where you need it (like checking contrast in your own UI).
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. Stefan Van Damme is the solo developer and has maintained the extension with monthly updates for over 15 years.
