The most powerful and the fastest content blocker, used by over a million people on iOS and Mac. Essential app for anyone who uses Safari.

Unlike other adblock apps, we can't see what sites you visit and track you. That’s because 1Blocker is a native Safari content blocker, not a shady VPN server. We are supported entirely by our users, there’s no “acceptable ads” program.


1Blocker has been featured in The New York Times, TechCrunch, and many more.

• “I like 1Blocker enough that I’ve stopped thinking about blockers.” - John Gruber, Daring Fireball.
• “Switched from Ghostery to 1Blocker for macOS Safari, which uses the fast new content-blocking API, and it seems noticeably faster.” - Marco Arment.
• “Does exactly what you want it to do, and the customer support is fantastic. Highly recommended ad blocker.”


- Block annoying ads (adblock) -
Ads have become a total disaster on websites by ruining the browsing experience. No one likes to see ads that pop over the entire screen.

- Save battery, data and time -
Independent tests by Wirecutter, NY Times, and BrooksReview confirm that 1Blocker cuts data loaded by sites on average by over 50%.

- Protect yourself online -
Many corporations track your behavior and what sites you visit. Online ads are not safe and may serve you malware even on major sites like Forbes and Yahoo.

- Improve your productivity -
Besides ads, webpages often contain distracting elements (like “You Might Also Like” and subscription boxes) that disturb your work flow and productivity.


1Blocker comes with almost 50 000 built-in blocker rules. It is very configurable.

• Block ads, trackers and other annoyances. Make browsing over 2x faster.
• Tap to hide any annoying content with our visual editor.
• Support sites you love by whitelisting them.
• Create your own custom blocker rules (hide elements, block sites and cookies).
• All your settings are synced over iCloud.

1Blocker is also available for iOS in the App Store.


We believe 1Blocker is better than anything else available. Here is why:

• We don’t make deals with advertisers.
• We don’t and technically can’t track our users.
• We have no customer data to sell.
• We are bootstrapped and self-funded. No investors. Made by a tiny two-person team.


While most other adblock apps block content by filtering elements of an already downloaded page, 1Blocker uses native Safari content blocker technology (API) to tell Safari in advance what should be blocked. This vastly improves efficiency, doesn’t slow down Safari, and saves battery life.

Not the cheapest, but certainly the best!

I’d used other blocking apps for years but after a clean install of MacOS, I decided to give 1Blocker a try rather than re-installing my old, clunky blocker. Honestly, I’d never go back to those other blockers now. It’s awesome to have a native Mac app with which to configure the blocker and it’s nice to have a blocker that works with the Safari content blocker API rather than being a hacky browser extension as the others all are. The small fee for this app is well worth the price! Trust me, you won’t regret buying 1Blocker! Thanks a million Salavat!


Junk - don’t waste your money!

This is the worst performing piece of software I have ever used. Firstly, it doesn’t block ads. I have had better results from free adblockers. I had to change from Adblock PLus due to the most recent update of Safari. Since installing this half-baked app, my system slows to a stop and I keep getting the coloured spinning wheel for minutes at a time after which the ads appear!! Secondly, it actually blocks and fails to display any comments left by readers of newsfeeds or sports blogs. Having paid good money for this, I expected it to at least perform. It doesn’t. Don’t waste your money!


The whitelist with many items has gone

I’ve had a whitelist with hundreds of sites in 1 list. I wanted to remove just one site from that list, I did it using your Safari extension and now the entire whitelist has gone. I have spent a lot of time by adding sites to the list and it is ridiculous that now all of them are gone. You cannot release such a buggy and untested product!!
Now tell me how I can restore that list back!

Wouldn’t reccomend buying this buggy application and also application for iOS as it also won’t let you edit whitelist, you can see only 1 item from the whitelist when you trying to edit it!

Seems that developer just trying to raise money without real development and product improvement!
