How to block websites on Chrome

Free, takes under a minute · Updated November 11, 2026

Chrome has no setting for blocking a site you keep opening out of habit, so you need an extension. This guide uses Bonk. It's free, it needs no account, and there's no limit on how many sites you block.

Once a site is blocked, opening it shows Bonk's own page instead, with a nudge back to work and a count of how many times you tried.

Block a website in four steps

Add Bonk to Chrome from the Chrome Web Store.
Click the Bonk icon in Chrome's toolbar. If you can't see it, click the puzzle piece icon and pin Bonk.
On the Sites tab, type the site into the box, for example reddit.com. To add several at once, separate them with commas.
Click Block.

That's it. Open the site in a new tab to test it. You land on Bonk's blocked page, and the site appears in your list with a count of today's attempts. Subdomains are covered too, so blocking reddit.com also blocks old.reddit.com.

Block part of a site instead of all of it

Sometimes you only want to lose one part of a site. Type the address with the path, like youtube.com/shorts, and only that part is blocked while the rest of the site keeps working. There's a full walkthrough in how to block YouTube Shorts.

Block a whole category in one click

Instead of typing sites one by one, open Categories and YouTube under the box and tap a tile. The ready-made lists are Social media, Video and streaming, News, Shopping, Clothing and fashion, Gaming, Adult and Gambling. Each one covers dozens of sites, and you can still add your own on top. The social media list is covered in how to block social media on Chrome.

Unblock a site

Click the × next to the site in your list. It's open again straight away. If you've set up hard mode, the list is locked until the timer ends.

Block sites in incognito windows too

Chrome switches extensions off in incognito windows unless you allow them. Open Bonk's Settings tab, find Incognito windows, and click Turn on in Chrome. Then switch on Allow in Incognito on the page Chrome opens. Bonk's Settings tab tells you whether it's on.

Make the block stick

A plain block is easy to switch off when the urge hits. To make it harder, block on a schedule so it runs without you, set a daily time limit instead of a hard stop, or lock Bonk with hard mode.

Add Bonk to Chrome, it's free

Questions

Is it really free?

Yes. Blocking sites has no limit and no trial period. Bonk Pro adds extras, like hard mode sessions longer than an hour, but you don't need it to block websites.

Do I need an account?

No. Your lists, schedules and stats stay in your browser.

Does it block every country version of a site, like amazon.co.uk and amazon.de?

Add each address you want blocked. A wildcard like amazon.* covers them all in one entry, but wildcards are a Bonk Pro feature.

Will it block sites on my phone?

No. Bonk is a Chrome extension, so it blocks sites in Chrome on the computer where you installed it.

Is a blocked site gone for good?

Only for as long as it's on your list. Remove it and it opens normally again, and nothing is deleted from the site itself.
