Website Blacklist is a chrome site block extension that blocks the sites that eat your time — with schedules, a focus mode for deep work, and an optional password so a weak moment can't undo your rules.
Free · No account · Works entirely offline
Not just a list of banned domains — a full toolkit for staying focused on your terms.
Click the toolbar icon and blacklist whatever tab you're on instantly — the fastest way to block sites on Chrome, or add any site by hand.
Blacklist a whole domain and its subdomains, a keyword anywhere in the URL, or write a custom pattern — covers how to block site in Chrome for URLs, not just domains.
Answers how to restrict websites on Chrome during work hours or weekdays only — outside the window, sites unblock automatically.
Start a 25-, 50-, or 90-minute focus session that blocks everything on your list immediately, Pomodoro-style.
Lock down the actions that matter — turning off blocking, deleting a site, editing the schedule — behind a password.
Back up your website blacklist as a JSON file, move it to another computer, or share a curated blacklist with a friend.
See exactly how many times each site tried to pull you back in, and how that trends over time.
No accounts, no analytics, no network requests. Your website blacklist lives only in your browser's local storage.
Built with Chrome's own design language, so it feels right at home.
Add Website Blacklist, a chrome site block extension, from the Chrome Web Store — no account or sign-up required.
Click the toolbar icon on any site to blacklist it, or add domains and patterns from the settings page — the quickest way to block sites on Chrome.
Set a password, a schedule, or start a focus session — and let the extension hold the line for you.
Website Blacklist works entirely offline. There's no backend, no account, and no analytics SDK — the extension simply can't see your browsing history even if it wanted to.
Website Blacklist asks for the minimum Chrome permissions needed to intercept and redirect page loads. No permission is used to read page content — only to match and redirect the URLs you've blocked.
Install Website Blacklist, click the toolbar icon on the page you want gone, and it's added to your blacklist immediately — no settings menu required for the basic case.
Open the schedule tab and pick the days and hours to enforce. Outside that window every blacklisted site loads normally, automatically.
Yes. Use “Domain” to blacklist a site and all its subdomains, “Contains” to block any URL containing specific text (like a path such as /shorts), or “Custom” to write your own pattern — this chrome site block extension supports all three.
No. Website Blacklist makes no network requests of its own. Your blacklist, schedule, and stats are stored locally in Chrome's extension storage and never leave your device.
You can — password protection is a speed bump for impulse, not a hard lock. Anyone with access to the device could still remove the extension. It's designed to stop a moment of weakness, not a determined workaround.
No. Blocking runs on Chrome's native declarativeNetRequest engine, the same fast, built-in system ad blockers use — nothing inspects every request in the background.
Install Website Blacklist and set up your first website blacklist in under a minute.
