## What it is
Dark Reader is an open-source MIT-licensed browser extension that analyzes web pages and generates a customizable dark mode to reduce eyestrain. It works on Chrome, Firefox, Safari, Edge, and Thunderbird, with per-site configuration of brightness, contrast, and sepia.

## Use cases
- enable dark mode on every website
- reduce eye strain while browsing at night
- apply dark theme to sites without native dark mode
- configure dark mode per domain
- adjust brightness and contrast of web pages

## When to choose
- you want dark mode across all websites in your browser
- you need per-site customization of dark theme settings
- you want a privacy-respecting extension that sends no user data

## When to avoid
- you only need dark mode for a single site with native support
- you need a dark theme for desktop applications rather than the browser
