Dark Reader
An open-source dark mode for websites. Free extension, with brightness, contrast and sepia controls.
Why it's a strong pick
Dark Reader is open source under the MIT licence, so anyone can read its code. Its README says it "analyzes web pages and generates dark mode to reduce eyestrain". Its developers say it shows no ads, and its privacy policy says it has never collected personal data. The trade-off: it recolours pages itself, so a few sites can look off.
What it does
Dark Reader turns on a dark theme for the sites you visit. You can change brightness, contrast and sepia. It keeps site-specific fixes that update with new releases. It works in Chrome, Firefox, Safari, Edge and Thunderbird. There is a per-site switch, so you can turn it off where a page already looks fine.
Key features
- Generated dark mode. The README says it analyses each page and builds a dark theme to reduce eyestrain.
- Brightness, contrast and sepia. You can adjust all three.
- Site-specific fixes. The README says these sync with new releases. It also describes developer-tools controls for restricted pages.
- Open source. MIT licence, code on GitHub.
- Optional paid Plus. Dark Reader Plus offers premium themes and custom colours. Its page says it is available for Microsoft Edge on Windows, macOS and Android. We could not confirm it for Chrome. Check current plans on its site.
Who it's for
Dark Reader suits people who want a dark look on many sites without hunting for each site's own dark mode. It is a good first extension to try in this category. If you want finer colour control, look at Midnight Lizard. If you only read articles, a reader view such as Reader View may be enough.
Is Dark Reader safe to install?
Dark Reader's developers publish a privacy policy that says they have never collected personal data or browsing history. It is open source under MIT. One real risk is lookalikes: other listings use similar names, and the developers warn about copycats. Install from the listing we link. Our safety check goes through it in detail.
What permissions does Dark Reader ask for?
Its Chrome manifest in the public repo lists storage, scripting, alarms and fontSettings, plus access to all sites. All-sites access is how it can recolour any page you open. That is the repo's manifest, so check the install prompt for the current list before you install.
Does Dark Reader work with Manifest V3?
The repo has a Chrome Manifest V3 file, so the code is built for Chrome's current extension format. We could not confirm which format the Chrome Web Store build uses, so check the listing. The repo's changelog shows a release dated 24 September 2026, so the project is still being updated.
FAQ
Is Dark Reader free? The extension is described as free. A paid option, Dark Reader Plus, exists; its page names Edge as the supported browser. Check current plans on its site.
Is it open source? Yes. The licence is MIT and the code is on GitHub.
Does it need an account? We found no description of a sign-up step. Check the listing before you install.
Good to know
Because Dark Reader recolours pages itself, a few sites look odd or load slowly. Use the per-site off switch and the site-specific fixes. For full control of a site's look with your own CSS, Stylus is a different kind of tool.
