Dimly — Screen dimmer for bright pages

About

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.

WHY PEOPLE USE DIMLY
• Reduce eye strain on bright or white-background pages
• Browse comfortably at night or in dark rooms
• Helpful for light sensitivity, glare, and migraines
• A clean alternative to dark mode on sites that don’t support it

FEATURES
• Global dimmer: One slider adjusts brightness across all tabs
• Per-site control: Save different dimming levels for each site and lock them
• Scheduling: Set custom times or create a nighttime routine with smooth fades
• Quick toggle: Turn dimming on or off instantly
• Works on most sites: Chrome blocks internal pages such as chrome:// and the Web Store
• Lightweight and private: No ads, no tracking, no analytics
• Open source: Full code available on GitHub

HOW DIMLY HELPS
Dimly gives you consistent, comfortable brightness on every website, even pages that don’t offer a dark theme. 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.
