Block ads, trackers & more with 1Blocker

By Salavat Khanov

Open the Mac App Store to buy and download apps.


Block ads, trackers, and any annoying web content. Based on new lightning fast native Content Blocking API, it doesn’t slow down Safari and can't know which websites you visit. We are supported entirely by our users, there’s no “acceptable ads” program.


1Blocker is the fastest & most powerful Safari content blocker. With over 40 000 preinstalled blockers, it's highly configurable.

• Simply tap on any webpage element — like sidebar, site logo or subscription box — to hide it using our Safari extension.
• Quickly whitelist websites you love.
• All your blocking preferences are automatically synced over iCloud.
• Create your own custom blocker rules (hide page elements, block sites, and cookies).


1Blocker is a leading content blocker for iOS and macOS. It has been featured in The New York Times, TechCrunch, LifeHacker, and many more. What our customers say:

• “Does exactly what you want it to do, and the customer support is fantastic. Highly recommended.” — Blocky McBlockerson
• “The author put a lot of hard work into creating 1Blocker, and it really shows. I’m using it on both my Mac and my iPhone, and I’m very satisfied.” — Artiste212
• “If you’re on the fence about trying this adblocker I wholeheartedly recommend you give it a try! Definitely worth it!” — ChronicLynx


While most other extensions block content by filtering elements of already downloaded page, 1Blocker uses modern WebKit blocking technology to tell Safari in advance what should be blocked. This vastly improves efficiency and saves battery life.


1Blocker is not a VPN or proxy server, it can't see what web pages you visit and doesn't expose your privacy.

We are fully supported by our users — we don't make deals with advertisers or sell your data to publishers.

What's New in Version 1.3

Hello again, dear customer! In this update, we're excited to finally release a new feature which makes blocking annoying content on websites really easy. Right in 1Blocker Safari extension, you can now simply tap on any page element — like sidebar, site logo or subscription box — to hide it.

Customizing your favorite websites has never been easier.

Moreover, there are a few subtle improvements throughout the app which make the experience of using 1Blocker so much better. For example, you can now search rules not only by their name, but also by domains to which they are applied.

As always, we've also updated our preinstalled blocker ruleset and fixed many common issues with popular websites. Here are a few examples:
- Links on Macworld can now be accessed as normal.
- Comments on Trello and Airbnb are no longer blocked.
- Email subscription links open correctly in Safari.

Important: please launch the app to apply new preinstalled rules.

We love hearing from you! Send your feedback at @1BlockerApp on Twitter.

Top class blocker

Not all “blockers” are created equal…and there’s virtually no guarantee that a product will work. I’ve had a chance to see how iBlocker works on iOS, and I was instantly sold; the performance difference alone was quantifiable and convincing.

The speed differences on MacOS are subtler, since the Mac already does a good job filtering traffic that could harm your computer. Since iBlociker is seriously configurable, you can see how many filters are built in to stop third party traffic. But the difference is clear on start-up alone. Without 1Blocker, there was an obvious slowdown on my already fast machine; with 1Blocker, the slowdown was gone. It’s really doing its job.

The real clincher was the ability to configure. If you want to block a single site, or a class of sites, you can do it.

Still not as good as the (“free” but shady) alternatives

I like the idea of paying for an ad blocker rather than having companies stack its deck. So 1Blocker always seemed like an attractive option. However, I've been using it off-and-on for a year and I've found it to be a very frustrating experience:

- I get the same "user error" constantly while editing rules. All I found online are people complaining about this since last year.
- It simply doesn't block some ads for some reason. I'm not sure what competitors like uOrigins do that 1Blocker doesn't but the latter is much less consistent for some reason. It doesn't even block all the ads on the test-your-ad-blocker websites (the competitors do).
- The "hide elements" feature doesn't work on most elements I've tried.
- There's no keyboard shortcut key to delete rules. There's also no way to bulk delete. Right clicking on every rule is tedious. There's no way to start "fresh," as far as I can tell. A "default" button would be nice.

All in all, I've found that this ad blocker is much higher maintenance than all the others but without the benefits of better ad blocking. So unfortunately I keep going back to the more venal competition.


The blocker is very useful and configurablel, especially with the ability to sync configuration via iCloud to other Macs and iOS devices. What I would like to see though is the concept of a blacklist mode that would allow ads (aka "Block Ads" rules not applied) unless a website is on the blacklist - ideally other rule sets such as “Block Trackers” would still apply. I’m probably in the minority for this desire, but this way I can go ahead and give all sites the benefit of the doubt until they annoy me which if I have to continue using the site for some reason I can add the site to the blacklist rather than attempting to whitelist all sites.
