Dark Reader analyzes web pages and aims to reduce eyestrain while browsing the web.
Dark Reader is an open-source MIT-licensed browser extension designed to analyze web pages. Dark Reader will generate a dark mode that aims to reduce the eyestrain of the user. Dark Reader is feature-rich and is customizable in many ways throughout the UI.
Most questions can be answered by reading the help page. If the help page doesn't answer your question, open up a new discussion.

You can install the extension from a file. Install Node.js (we recommend LTS or higher, but any version at or above 15 will work). Download the source code (or check out from git). Open the terminal in the root folder and run:
npm install
npm run build
ornpm run build [-- flags]
This will create a build/release/darkreader-chrome.zip
file for use in a Chromium-based browser and a build/release/darkreader-firefox.xpi
file for use in Firefox.
You can customize build process by passing flags to build script. To see all flags, run npm run build -- --help
.
You can use Dark Reader to enable dark mode on your website!
- Install the package from NPM (
npm install darkreader
) - or build from the source code (
npm run api
) - or include the script via a CDN such as unpkg or jsDelivr
Then you can use the following code to control Dark Reader's API:
DarkReader.enable({
brightness: 100,
contrast: 90,
sepia: 10
});
DarkReader.disable();
// Enable when the system color scheme is dark.
DarkReader.auto({
brightness: 100,
contrast: 90,
sepia: 10
});
// Stop watching for the system color scheme.
DarkReader.auto(false);
// Get the generated CSS of Dark Reader returned as a string.
const CSS = await DarkReader.exportGeneratedCSS();
// Check if Dark Reader is enabled.
const isEnabled = DarkReader.isEnabled();
... or if you are using ES modules:
import {
enable as enableDarkMode,
disable as disableDarkMode,
auto as followSystemColorScheme,
exportGeneratedCSS as collectCSS,
isEnabled as isDarkReaderEnabled
} from 'darkreader';
enableDarkMode({
brightness: 100,
contrast: 90,
sepia: 10,
});
disableDarkMode();
followSystemColorScheme();
const CSS = await collectCSS();
const isEnabled = isDarkReaderEnabled();
Be aware that Dark Reader will add the chrome
object onto the window
object. These are to stub certain functions that the code will use. They originate from the webextension-api.
Automatically syncing the site fixes to every Dark Reader user was disabled because the GitHub team does not allow using GitHub as a CDN. The storage of these files would be expensive, and making requests to other resources would look suspicious. Each new release of Dark Reader will include these changes.
However, this can be enabled using the following steps:
- Click on the Dark Reader icon.
- Click on the Dev tools button (in the bottom-right corner).
- Click on the Preview new design button.
- Enable the
Synchronize site fixes
setting underSettings -> Manage Settings
.
To force a synchronization of the sites fixes (when the corresponding setting is enabled), perform the following steps:
- Click on the Dark Reader icon.
- Click on the Dev tools button (in the bottom-right corner).
- Click on the Reset button. This will remove any custom site fixes you may have.
