How do I block distracting websites on Chrome for free?

Install a free blocker like Focuh from the Chrome Web Store, add the sites that eat your time, and start a challenge. It takes under a minute and needs no account. Each blocked tab then redirects to a quiet local page, and the extension counts how often you tried to open it. That covers distractions in Chrome, but not other browsers or native apps — for those you need a system-level blocker on top, which the same team makes for Mac.

What counts as a distracting website worth blocking?

The honest test is which sites you open on autopilot when a task gets hard, not which ones feel guilty. For most people that's the infinite-scroll feeds — YouTube, Reddit, X, Instagram, TikTok — plus news sites and forums you re-check out of habit. Start with the two or three you reach for without deciding to, watch the attempt counter, and add any site you catch yourself opening to dodge the block. A lived-in list beats a long aspirational one.

Will a Chrome extension block distracting websites in other browsers?

No. A Chrome extension only works in Chrome. Open the same site in Safari, Firefox, or Edge and it loads normally. Focuh is a Chromium extension, so it also runs in Edge, Arc, Brave, and Opera, but you install it separately in each because extension storage is per-browser. If you tend to switch browsers when one blocks you, a single-browser extension leaves an obvious workaround, so for full coverage you block below the browser instead.

Can I still open a blocked site if I genuinely need it?

Yes. Any Chrome extension can be turned off from chrome://extensions, so you can disable the block, use the site, and re-enable it. That's intentional — a free extension interrupts the reflex of opening a distraction rather than locking you out permanently. If you want a block that's genuinely hard to lift in the middle of a focus session, that has to happen at the operating-system level, which a browser extension can't do on its own.

How long should I block distracting websites for?

Long enough to break the habit, not just an afternoon. Focuh runs challenges of 30, 91, or 180 days, or a custom range, rather than an hour at a time. Reaching for a distraction the second a task gets dull is a reflex built over months, so a short block rarely sticks. A 30-day challenge gives the habit time to fade, and the attempt counter shows how many times the urge fires in a normal workday — which is usually more than people expect.

Do free Chrome blockers slow down your browser?

Generally no. A well-built blocker like Focuh only checks the top-level hostname against a local list when a tab navigates, which is negligible work. Heavier extensions that scan page content, sync to a server, or load remote scripts can add noticeable overhead — but those are usually the freemium ones, not the lightweight free ones. If a blocker asks for broad permissions or an account, that's worth a second look before you install it.

Should I block sites all the time or only during work?

Timed blocking usually beats an all-day ban, which turns a site into forbidden fruit and invites a workaround. Block your distractions for a single focus session — say 50 or 90 minutes — then let them back on a break. Focuh ties the block to a challenge so it's part of a routine rather than a punishment. You rarely need a site gone all day; you need it out of reach during the stretches where you're actually building something.

What's the most reliable way to block distracting websites?

Block them at every layer you actually use: the browser with an extension, other browsers and native apps with a system-level tool, and the phone with its built-in screen time. A Chrome extension covers only the first browser. On a Mac, the free Focuh app blocks your site list across every browser and can block native apps too, which closes the gaps an extension leaves. The extension plus the Mac app together is the setup that holds when you're tired and looking for a way around it.

How to Block Distracting Websites on Chrome (Free) — 2026

June 15, 20269 min readFocuh

When a task gets hard, the hand moves before the brain does — new tab, a site you've opened ten thousand times, and the focus is gone. Blocking your distractions is the cheapest way to put friction between the urge and the scroll. This guide shows how to block distracting websites on Chrome for free, in about a minute, with no account — plus an honest take on where a browser extension stops.

The fast answer

To block distracting websites on Chrome for free, install Focuh from the Chrome Web Store, add the sites that eat your time, and start a challenge. Every blocked tab then redirects to a calm local page, and the extension counts your attempts so you can watch the habit fade. There's no account, no three-site cap, and no telemetry. The catch: this blocks distractions in Chrome only — other browsers and native apps stay open unless you handle them separately.

How to block distracting websites on Chrome step by step

Open the Chrome Web Store and search for Focuh, or go to the Focuh extension page.
Click Add to Chrome, then Add extension. No account, no email.
Click the Focuh icon and add the sites you want gone (a starter list is below).
Pick a challenge length — 30, 91, or 180 days, or a custom number — and start it.

From that point, any attempt to load a blocked site in Chrome redirects before the page renders. You don't get a flash of the feed first. Each attempt bumps a counter, and that number is the most useful part: the open-a-distraction habit hides in plain sight, so watching it tick up fifteen times before lunch makes the reflex impossible to ignore.

What should go on your blocklist?

Don't build a moral list — build an honest one. The sites worth blocking are the ones you open on autopilot when a task stalls, not the ones that merely feel like junk food. A solid starter set for most people:

Feeds: youtube.com, reddit.com, x.com, instagram.com, tiktok.com
News: the two or three outlets you re-check out of habit
Forums and aggregators: whatever you reload between tasks
Shopping: amazon.com if "just looking" eats your afternoons

Start with the two or three you reach for without deciding to. Focuh matches on the hostname, so each entry covers the domain and its subdomains, and there's no three-site cap — so when you catch yourself opening a fourth site to dodge the block, you just add it.

The catch: a Chrome extension only blocks Chrome

Here's the part worth saying plainly. A Chrome extension controls Chrome tabs and nothing else. Block youtube.com in Chrome and it still loads the instant you open Safari, Firefox, or Edge — and if your distraction has a desktop app, like YouTube or a chat tool, the extension never sees it.

So a Chrome-only block works in one case: your distractions live in a Chrome tab and you won't reflexively reopen them elsewhere. If that's you, the extension is enough. If you keep a second browser a keystroke away, or your real leak is a native app, the website block alone closes the front door while the back one stays open. The full breakdown of where a browser block holds and where it leaks is in system-level vs browser website blocking.

Free ways to block distracting websites on Chrome, compared

Method	Free?	Blocks web	Blocks native apps	Blocks other browsers	Setup time
Focuh extension	Yes	Yes	No	No	~1 min
StayFocusd	Yes	Yes	No	No	~3 min
Hosts file edit	Yes	Yes	Partial	Yes (desktop)	~10 min
Focuh Mac app	Yes	Yes	Yes	Yes	~3 min

The only rows that reach native apps and other browsers aren't Chrome extensions at all. That's the trade-off in one table: an extension is the fastest way to block distractions in your main browser, but by definition it can only block that browser. For anything beyond Chrome, you block at the system level.

How do I block distracting sites everywhere on a Mac?

If a second browser is your usual escape hatch, block below the browser. On a Mac, the free Focuh desktop app does this with macOS Accessibility APIs — during a focus session it blocks your whole site list across Chrome, Safari, Firefox, and the rest, and it can block native apps too. Because it doesn't live in chrome://extensions, it's harder to switch off mid-session than an extension.

The most reliable desktop setup is both layers: the free Focuh Chrome extension for your main browser, plus the free Focuh Mac app for every other browser and any native-app distractions. Both are free, so running both costs nothing. If single sites are the bigger problem, the per-site guides go deeper — for example, how to block YouTube on Chrome and how to block Reddit on Chrome.

Block during work, not all day

A blanket all-day block often backfires — it turns a site into forbidden fruit and invites a workaround the moment you're tired. Tying the block to specific stretches tends to stick better.

Focuh's challenge model keeps your distractions out of reach while you work and lets them back when you're done, so the block reads as part of a routine rather than a punishment. You rarely need a site gone every waking hour; you need it gone during the focus blocks where you're actually building something. Start a challenge, do the work, and let the feeds back on a real break — the time you reclaim is the time the open-a-tab reflex was quietly eating.

Which option should you pick?

Your distractions live in a Chrome tab — install the Focuh extension, add your site list, start a challenge.
You switch to another browser to get around it — you need system-level blocking on a Mac, not a single-browser extension.
Your leak is a native app — the website block won't touch it; use the free Mac app for app-level blocking.
You want everything covered — the Chrome extension plus the free Mac app, plus phone screen time.

No blocker fixes focus on its own, and a Chrome extension won't follow your distractions into a second browser or a native app — be honest about where you actually reopen them. Install Focuh free for the browser, and get the free Mac app when you need the block to hold everywhere.
