Dimly — Screen dimmer for bright pages

Dim any site with a global slider or per-site levels. Quick lock, scheduling, smooth fade.

Dimly is a simple, lightweight screen-dimmer that makes bright websites easier on your eyes. Instead of adjusting your monitor or system settings, Dimly adds a soft, adjustable dimming layer on top of the sites you visit. It works on most websites and gives you fine control over page brightness in a way dark-mode themes can’t.

It’s a universal, low-impact solution for users who struggle with bright screens or want more control than standard dark-mode extensions provide. PRIVACY Dimly does not collect, sell, or share personal data. All brightness levels, per-site settings, and schedules stay inside your browser. Nothing leaves your device.
