What's the easiest way to block YouTube on Chrome for free?

Install a free blocker like Focuh from the Chrome Web Store, add youtube.com to its blocklist, and start a challenge. The whole process takes under a minute and doesn't require an account. The extension redirects any YouTube tab to a quiet local page and counts the attempts.

Can I block YouTube without using an extension?

Yes, but the options are limited. You can edit the hosts file on macOS or Linux to map youtube.com to 127.0.0.1, which blocks YouTube system-wide across all browsers. This requires admin access and a terminal, and it's easy to forget you've done it. For most people, a free extension is faster and cleaner than editing system files.

How do I block YouTube during work hours only?

Focuh blocks for the duration of a self-imposed challenge (30 days, 91 days, 180 days, or a custom range) rather than scheduling per-day windows. For schedule-based blocking — block 9am to 5pm on weekdays, free on weekends — LeechBlock NG offers granular scheduling, or the Focuh desktop app for Mac can schedule focus sessions tied to your calendar.

Will blocking YouTube also block YouTube Shorts and YouTube Music?

Blocking youtube.com will also block youtube.com/shorts since Shorts lives under the same domain. YouTube Music runs on music.youtube.com, so you'll need to add that separately if you want to block it too. The YouTube mobile and desktop apps are not affected by a Chrome extension — those need system-level blocking.

Can I unblock YouTube if I really need to access it for work?

Yes. Chrome extensions can be disabled from chrome://extensions, so you can always turn off the blocker temporarily. This is by design — Focuh is intended to interrupt the reflex, not to be unbreakable. If you need YouTube for legitimate research, disable the extension, use it, and re-enable. For stricter blocking that's harder to circumvent mid-session, the Focuh desktop app for Mac is the better fit.

Does blocking YouTube on Chrome work in Brave, Edge, or Arc?

Yes. Focuh is a Chromium extension, so it works in any Chromium-based browser that accepts Chrome Web Store extensions — Brave, Edge, Arc, Vivaldi, and others. You'll need to install it separately in each browser since extension storage is per-browser.

How to Block YouTube on Chrome (Free, No Account) — 2026

May 29, 20268 min readFocuh

YouTube is the productivity killer that doesn't feel like one. You open a tab to look up one specific thing, and forty minutes later you're watching someone explain why airline food is the way it is. This guide shows you how to block YouTube on Chrome for free, in about a minute, without an account or a subscription.

It also covers what to do about the YouTube desktop app, YouTube Music, and YouTube tabs in other browsers — the workarounds that make most Chrome-only blocks fall apart by week two.

The fast answer

To block YouTube on Chrome for free, install Focuh from the Chrome Web Store, add youtube.com to the blocklist, and start a challenge. The extension redirects YouTube tabs to a quiet local page and counts the attempts. There's no account, no 3-site cap, no telemetry, and no paid tier.

For total YouTube blocking — including the desktop app, YouTube Music, and YouTube on Safari — install the free Focuh desktop app for Mac on top of the Chrome extension. The desktop app blocks at the macOS system level, so it catches every other entry point.

Step-by-step: block YouTube on Chrome (free)

These steps assume you're using Chrome on a Mac or Windows machine. The same process works in Brave, Edge, Arc, and other Chromium browsers.

1. Install Focuh

Open the Focuh page and click the install button. Confirm the permission prompt — the extension requests storage, webNavigation, and host permissions to check the current page hostname locally against your blocklist. No data leaves your device.

2. Open the extension options

Click the Focuh icon in your Chrome toolbar (or right-click the icon and select "Options" if you've pinned it). You'll see a simple options page with two sections: blocklist and challenge.

3. Add youtube.com to the blocklist

In the blocklist input, type youtube.com and press Enter or click Add. The extension accepts plain domain names — no need for http://, www., or trailing slashes. If you also want to block:

YouTube Shorts: covered by youtube.com (Shorts live under the same domain)
YouTube Music: add music.youtube.com separately
YouTube TV: add tv.youtube.com separately
YouTube Studio: add studio.youtube.com if you want to block creator workflows too

4. Set a challenge duration

Pick how long you want YouTube blocked. Options:

30 days — a focused sprint, useful for one project
91 days — a quarter, long enough to break a habit
180 days — six months, for habits that have been stuck for years
Custom — any specific number of days

The challenge runs in the background. Every time you try to visit YouTube during the challenge, the tab redirects and the daily attempt counter increments by one.

5. Open a YouTube tab to test it

Type youtube.com in a new tab. You should see Focuh's local blocked page instead of YouTube. The page is intentionally quiet — no marketing, no nag screen, just a confirmation that the block is working. Your daily attempt count for youtube.com ticks up by one.

That's it. You're blocked.

Alternative methods (with honest trade-offs)

The Chrome extension method is the fastest path to blocking YouTube, but it's not the only one. Here are the alternatives and when they make sense.

Edit the hosts file (macOS / Linux)

You can block YouTube system-wide by mapping youtube.com to 127.0.0.1 in your hosts file. On macOS:

sudo nano /etc/hosts

Add:

127.0.0.1 youtube.com
127.0.0.1 www.youtube.com

Save and flush DNS cache:

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

Pros: blocks YouTube in every browser and every app, no extension needed. Cons: requires admin access, easy to forget you set it up, doesn't track attempts, harder to undo. The hosts-file approach also won't block IP-based access, though most users won't hit that.

Use a free desktop blocker

Focuh for Mac, SelfControl, and Cold Turkey's free tier all block at the macOS system level — so the block applies to Chrome, Safari, the YouTube desktop app, and every other browser. The Focuh desktop app is the only one of the three that's free without a one-time purchase or upgrade nag.

This is the right path if your YouTube problem extends beyond Chrome.

Use Chrome's built-in time limits (Family Link)

If you set up Chrome under a child account or use Google Family Link, you can set a per-site time limit for YouTube. This works for the use case it was designed for (parental controls) but is overkill if you're trying to block your own access. Most adults end up running their primary account, not a managed account.

Use a paid blocker

BlockSite Premium, Cold Turkey Pro, and Freedom all support YouTube blocking with extra features — password protection, cross-device sync, locked modes. The trade-off is that none of them are free.

What about the YouTube mobile app or desktop app?

Chrome extensions only block what happens inside Chrome. The YouTube desktop app (on Mac, Windows, or as a PWA), the YouTube iOS and Android apps, and YouTube tabs in non-Chromium browsers like Safari and Firefox are all outside the extension's reach.

For full coverage:

macOS desktop apps: use Focuh for Mac, which blocks at the OS level across browsers and apps
Safari: install a Safari content blocker, or use the Focuh desktop app's system-level blocking
iOS: use Screen Time's App Limits (Settings → Screen Time → App Limits) to cap or block YouTube
Android: use Digital Wellbeing app timers, or a third-party blocker like ActionDash

The most reliable setup is layered: a free Chrome extension for tabs, a free desktop blocker for apps and other browsers, and the OS-level screen time controls for mobile.

How long should you block YouTube for?

Long enough to break the habit, not so long it becomes a permanent restriction you'll resent. The research is consistent that habit change takes longer than people expect — a 2009 study by Phillippa Lally at UCL found that habit formation took an average of 66 days, with a wide range across individuals and habits.

For most people, 30 to 90 days is the right starting range. 30 days breaks the reflex. 90 days lets a new default settle in. After that, you can usually leave YouTube unblocked and notice the reflex without acting on it. If you find yourself relapsing immediately when the challenge ends, do another challenge — there's no penalty.

A short note on why blocking YouTube works

YouTube is engineered to be hard to leave. The autoplay queue, the homepage thumbnails, the recommendation algorithm — all of it is designed to keep you watching. A 2024 study from the University of California, Irvine found that it takes an average of 23 minutes to fully refocus after a single interruption. That means a "quick check" of YouTube in the middle of focused work doesn't cost you the five minutes you spent on the video; it costs you closer to 28 minutes.

Blocking removes the choice. Once you can't get to YouTube, the autopilot reflex fires, hits a wall, and over time stops firing. The point of a free Chrome blocker isn't to make YouTube hard to access — Chrome extensions can be disabled. The point is to interrupt the autopilot long enough that you notice it.
