How do I block websites on Mac without using Screen Time?

Use a dedicated blocker or the hosts file instead. The fastest path is a free focus app like the Focuh Mac app: add the sites to its list and start a session, and they're blocked across every browser without touching Screen Time. For a no-install route, edit the hosts file in Terminal to point a domain at 127.0.0.1. For a block you can't cancel early, SelfControl runs a timer that can't be lifted until it ends. All three are free and skip Screen Time entirely.

Why do people avoid Screen Time for blocking websites?

Screen Time was built for parental controls and family device management, not personal deep work, and it shows. Its content limits are buried several menus deep, the allow/block lists are fiddly to maintain, and the whole thing leans on a passcode you set yourself — so in a weak moment you just enter your own passcode and you're through. People who block their own distractions usually want something faster to start and harder to talk themselves out of.

Can I block websites on Mac for free without Screen Time?

Yes. The Focuh Mac app is free with no account and blocks sites across all browsers during a focus session. The hosts file is free and already built into macOS — you just edit a text file in Terminal. SelfControl is free and open-source. None of them cost anything or require Screen Time. You only hit a paywall if you choose a freemium blocker like Cold Turkey Pro or Freedom, and even those have usable free or trial tiers.

Does blocking via the hosts file work in every browser like Screen Time does?

Yes, and that's its appeal. The hosts file sits beneath the browser, so a domain you block there fails to load in Safari, Chrome, Firefox, and Arc at once — the same system-wide coverage Screen Time aims for, without Screen Time. The trade-offs are that you edit it by hand in Terminal, you must add each subdomain and the www version, and there's no schedule or timer. It's a solid free baseline, not a managed solution.

What's the easiest Screen Time alternative for blocking sites during work?

A focus app you start and stop on demand. The free Focuh Mac app blocks your distraction list across every browser the moment you begin a session and lifts when the session ends, with an attempt counter so you can see the reflex firing. There's nothing to configure in System Settings and no parental-control framing. For a fuller side-by-side of options built for this, see the Screen Time alternative comparison and the best free app blocker for Mac roundup.

Can I make a block I can't undo without Screen Time's passcode?

Yes — that's exactly what SelfControl is for. You set a timer, hit start, and the blocklist is locked until the timer runs out. Restarting the Mac, deleting the app, or changing the clock won't lift it early. It's stricter than Screen Time's passcode model, where you can always just type the code you set. The downside is rigidity: there's no early exit even for a legitimate need, so use it for blocks you're sure about.

Will blocking websites without Screen Time also block apps on my Mac?

The hosts file and SelfControl mainly block domains, so they won't reliably stop native apps that connect by IP or their own resolver. If you also want to block apps — the Slack app, a game, a desktop client — you need a system-level blocker that handles applications. The Focuh Mac app can block apps as well as websites during a focus session. If app blocking is your main goal, start there rather than with the hosts file.

Is it safe to block websites with the hosts file instead of Screen Time?

Yes, as long as you only add new lines and leave the existing ones — like 127.0.0.1 localhost — untouched, since macOS relies on them. Add your blocked domains below the defaults, save, and flush the DNS cache. If anything looks off, remove the lines you added and flush again to restore the original behavior. Making a backup first with sudo cp /etc/hosts /etc/hosts.backup is a sensible precaution before you start.

How to Block Websites on Mac Without Screen Time

June 19, 20269 min readFocuh

You don't need Screen Time to block a distracting website on a Mac, and a lot of people are better off without it. To block websites on Mac without Screen Time, use a free focus app like the Focuh Mac app, edit the hosts file in Terminal, or run SelfControl's timed block — each works across every browser and skips Screen Time's parental-control plumbing entirely. This guide walks through all three and is honest about which one holds when you're tempted.

Why skip Screen Time in the first place?

Screen Time is genuinely good at the job it was designed for: a parent managing a kid's device. As a tool for blocking your own distractions during work, it fights you. The content restrictions live several menus deep in System Settings, the allowed/blocked lists are tedious to maintain, and the whole thing rests on a passcode you set yourself. That last part is the real flaw — when the urge hits, you type the passcode you already know and you're straight through. It's a lock where you're also holding the key in plain sight.

So the goal here isn't "Screen Time is bad." It's that personal focus wants different properties: fast to start, harder to talk yourself out of, and not buried in a settings panel built for someone else.

Method 1: a free focus app (easiest)

The simplest Screen Time alternative is a dedicated blocker you start and stop on demand. The free Focuh Mac app blocks your list of distracting sites across every browser the moment you start a focus session, and lifts when the session ends. There's no parental-control framing, nothing to configure in System Settings, and an attempt counter that shows how often you reached for a blocked site without meaning to.

For most people this is the right default. You add your distraction domains once, then it's a single action to block them for a work sprint. Because it blocks at the macOS level, it covers Chrome, Safari, Firefox, and Arc together — and it can block apps during a session too, which neither the hosts file nor SelfControl does reliably. For a wider look at apps in this category, see the best free app blocker for Mac.

Method 2: the hosts file (no install)

If you'd rather not install anything, macOS already ships with the tool. The hosts file maps a domain to your own machine so it fails to load, system-wide.

Open Terminal and back up the file: sudo cp /etc/hosts /etc/hosts.backup.
Open it for editing: sudo nano /etc/hosts.
Add one line per site, below the existing entries:
```
127.0.0.1 www.reddit.com
127.0.0.1 reddit.com
```
Save with Control-O and Enter, exit with Control-X.
Flush the DNS cache: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.

The site now fails to load in every browser. Add both the www and non-www version of each domain, since the hosts file matches the exact hostname. It's free and system-wide, but it's manual and trivial to undo — anyone can reopen the file and delete the line. The full walkthrough, including how to reverse it, is in how to block websites on Mac using Terminal.

Method 3: SelfControl (a block you can't cancel)

SelfControl is a free, open-source Mac app for one specific situation: you want a block you genuinely cannot lift early. You set a timer, add your sites, and start. Until the timer runs out, the block holds — restarting, deleting the app, or changing the system clock won't get you back in.

That rigidity is the whole point and also the catch. There's no early exit even for a legitimate need, so use it for blocks you're certain about. It's the strictest of the three and the right tool when your problem is that you'll always find a way to let yourself off the hook.

One practical note: because SelfControl and the hosts file both work on domains, neither reliably stops a native app that connects by its own resolver. If the thing eating your day is the desktop Slack app or a game rather than a website, domain blocking is the wrong layer — you want a tool that can block applications directly, which is where the Focuh app's session blocking comes back in.

The three methods compared

Method	Free	Blocks all browsers	Blocks apps	Hard to undo	Needs Terminal
Screen Time	Yes	Yes	Limited	Low (your own passcode)	No
Focuh Mac app	Yes	Yes	Yes (during session)	Medium	No
Hosts file	Yes	Yes	No	Low	Yes
SelfControl	Yes	Yes	No	High (timed lock)	No

The table makes the choice concrete. If your problem with Screen Time is that you can always enter the passcode, SelfControl's "no early exit" row is the fix. If your problem is that Screen Time is clunky to start and you want app blocking too, the Focuh app's flexibility is the fix. If you just want a free permanent baseline, the hosts file does it.

Which one should you use?

You want the easiest day-to-day block across browsers and apps — the free Focuh Mac app. Start a session, get to work.
You want zero installs and a permanent baseline — the hosts file, for the handful of sites you never want.
You want a block you can't talk yourself out of — SelfControl's timed lock.

These aren't mutually exclusive. A common setup is the hosts file as a permanent baseline plus a focus app for work sprints. If you're weighing Screen Time directly against a purpose-built blocker, the Focuh vs Screen Time comparison and the Screen Time alternative page lay out the differences feature by feature. And if you only need scheduled blocking, how to block websites on Mac on a schedule covers that path.

Screen Time isn't the only way to block a site on a Mac, and for personal focus it's rarely the best one. Pick the method that matches how stubborn the habit is, and put the friction where you'll actually feel it. Get the free Focuh Mac app if you want the simplest place to start.
