What is darkreader-extension?
darkreader-extension is a Chrome extension that automatically renders websites with a dark theme by dynamically adjusting CSS properties. It targets text, background, and link colors while preserving readability, and lets you customize per-site exceptions, contrast, and brightness.
Dark Reader injects CSS via the browser extension API, applying color transformations and inversion techniques to maintain legibility across pages. It runs within the extension process, leaves original HTML intact, and reverts changes when disabled.
Quick Fact: Dark Reader pioneered real-time CSS-based theming, enabling per-site tweaks and a system-wide dark experience without altering site content.
Types of Dark Reader Processes
- Browser Process: Main Chrome window and user interface interactions (1 instance)
- Renderer Process: Each tab and iframe may spawn a renderer for styling
- Extension Process: Dark Reader logic runs within the extension framework
- Utility Process: Background tasks like storage and settings synchronization
- Content Script: Injected CSS adjustments operate via content scripts
- Storage: Per-site preferences and color profiles are saved locally

- Startup or Session Restore: Chrome restores a previous session and re-launches Dark Reader to preserve user settings.
- Per-Site Overrides: Custom per-site dark mode rules are loaded, causing the extension to run to enforce those settings.
- OS Theme Matching: If configured, the extension may respond to system theme changes to maintain consistency.
