What 1Blocker does

1Blocker (1Blocker LLC) is a San Francisco-based, independently bootstrapped software developer founded in 2015 by Salavat Khanov. The company builds a Safari content blocker distributed exclusively through Apple's App Store across iPhone, iPad, Mac, and Apple Vision Pro. Its product combines a corpus of 45,000+ ad-blocking rules, 16,000+ tracker definitions, annoyance filters (cookie notices, pop-ups), and adult-content blocking across 2,700+ sites, with filter rules refreshed weekly from the cloud while all classification executes locally on the user's device.

The technology stack is built directly on Apple's Safari Content Blocker APIs, with a native client per Apple platform (iOS, macOS, visionOS) and platform-specific extensions such as the Mac-only 'See What's Blocked' transparency view and a Safari Button extension. Distribution relies on App Store Universal Purchase and Family Sharing, with no enterprise sales motion, no third-party channels, and no Acceptable Ads program. The company earns revenue solely through direct App Store sales of the app, using a freemium pricing model where the app is free to download with optional paid features.

1Blocker operates as a product-led, single-channel consumer business, deliberately independent of venture capital and ad networks. It positions privacy as a non-monetizable principle and depends on earned media coverage from technology press and word-of-mouth from tech journalists for top-of-funnel demand. The company's most recent major release, 1Blocker 6 (2025), refreshed the interface and improved blocking accuracy, and was distributed free to existing users.

Direct peers

• AdGuard: AdGuard ships cross-platform ad and tracker blockers for iOS, macOS, Android, and Windows with both free and paid tiers. It is the closest direct competitor to 1Blocker on the Apple side, with similar on-device filtering and a comparable freemium model, but with broader platform reach.
• Wipr: Wipr is a paid Safari content blocker for iPhone, iPad, and Mac that similarly emphasizes simplicity, low rule counts, and local filtering. It targets the same Apple-only niche as 1Blocker and competes head-to-head on the App Store.
• uBlock Origin: uBlock Origin (Raymond Hill) is a free, open-source content blocker widely regarded as the most powerful filter engine available. It is the dominant free alternative to 1Blocker on Safari desktop and sets the baseline users compare 1Blocker against.
• Ghostery: Ghostery is a privacy-focused ad and tracker blocker offering browser extensions and a private browser. It overlaps directly with 1Blocker's tracker-blocking value proposition on Safari and competes for the same privacy-conscious consumer.
• AdLock: AdLock provides cross-device ad blocking for iOS, macOS, Android, and Windows with both free and premium tiers. It is a directly comparable paid consumer ad blocker targeting the same Apple user demographic as 1Blocker.
• Disconnect: Disconnect builds privacy and tracker-blocking tools for browsers and mobile devices. It targets the same privacy-first consumer segment as 1Blocker and overlaps in functionality around tracker prevention and visual block counters.

Broad incumbents

• Adblock Plus: Adblock Plus (Eyeo) is the most widely installed ad blocker historically, with an Acceptable Ads program and multi-platform presence. It competes with 1Blocker on iOS and macOS and represents the incumbent paid/free model 1Blocker has explicitly positioned against.
• Brave: Brave is a privacy-focused browser with built-in ad and tracker blocking that ships on iOS and macOS. It competes with 1Blocker at the platform level by offering blocking as a free feature of a full browser rather than a standalone extension.
