A free porn blocker for Mac.

You open your Mac to get something done. An old browsing habit can pull you away. Nohub blocks porn and adult websites across all Mac browsers, with protection that runs on your device and progress you can check privately.

Keep the block when you switch browsers

One Mac setup. All your browsers.

A browser extension only covers the browser where you install it. Nohub blocks at the device level, so Safari, Chrome, Firefox, and other Mac browsers are covered by the same setup.

Compare free Mac options

Choose the blocking setup that fits your Mac.

Start with Apple’s built-in restriction, choose Nohub for a focused blocker with private progress, or use a more technical tool when you need custom control.

Use Screen Time without installing an app

Apple’s Limit Adult Websites setting is the simplest free starting point. It includes manual allow and deny lists, but it sits inside the broader Screen Time settings rather than a dedicated blocking app.

Follow the built-in Mac setup

Use Nohub for blocking plus private progress

Nohub gives you one focused shield across Mac browsers, plus a timer, levels, and milestones. Core blocking and progress tracking are free, with no required subscription or account.

Use a technical option for custom control

Filtered DNS, router controls, browser extensions, and local domain rules can each help, but they protect different surfaces and require more setup. Browser extensions only cover the browsers and profiles where they stay enabled.

Compare Mac options beyond Screen Time

Close the window. Keep blocking.

Once you activate the shield, blocking keeps working in the background even when the app is closed.

See the time you have built up

Your timer shows the time since you chose to stop. Levels and milestones give you a reason to check in without browsing.

Your progress stays on your Mac

You do not need an account. Your timer, levels, and milestones stay on your Mac, without tracking or public check-ins.

From download to daily use

Set up blocking on your Mac.

  1. Install Nohub from the Mac App Store. Open it on the Mac you want to protect.
  2. Complete setup and activate the shield. Follow the in-app instructions. You do not need an external VPN service.
  3. Check your browsers. Confirm blocking in the browsers, profiles, and private windows you use, then let it run in the background.
  4. Come back for your progress. Open Nohub to see your timer, current level, and next milestone.

A useful barrier, not a permanent lock.

Nohub is not impossible to bypass, especially if you control your Mac’s settings. No website filter catches everything. Recheck your setup after changing browsers or system settings, and treat blocking as support for your decision rather than a guarantee.

Mac blocking, answered.

Is Nohub a free porn blocker for Mac?

Core blocking and progress tracking are free. In-app purchases are optional tips, not a subscription or a requirement to use the core features. No account is required.

How do I block porn sites on Mac without a VPN?

Install Nohub from the Mac App Store, complete the short setup, and activate the shield. Blocking runs on your Mac itself; your traffic is not routed through an external VPN service or proxy.

Can I block adult websites on Mac without installing an app?

Yes. Apple includes a free Limit Adult Websites setting in Screen Time. It is a useful built-in starting point if you only need website restrictions and manual allow or deny lists.

Does it block adult websites in Chrome and other browsers?

Yes. Nohub blocks at the device level rather than inside one browser, so protection applies across all browsers on your Mac.

Does blocking stay active when the app is closed?

Yes. Once activated, Nohub keeps working quietly in the background. The app itself is mostly where you check your timer, level, and next milestone.

Can other people see my progress?

No. There are no accounts and no tracking. Your timer, milestones, and level are stored on your Mac and never sent to a server.

Put the block in place on your Mac.

Install Nohub, activate the shield, and get back to what you opened your Mac to do.
