What's actually built in

No extensions required — every feature below ships in the app itself.

🛡️

Real ad & tracker blocking

110,000+ rules from EasyList, EasyPrivacy, and AdGuard, compiled into Apple's native content-blocking engine — genuine network-level blocking, not just element hiding.

🖼️

Custom Picture-in-Picture

A fully custom floating video window — not the built-in browser PiP — up to 720p60, with the source video hidden from the page while it plays.

🔧

Full DevTools

Live network requests with resend, a console, and a live HTML editor — all built in, no extension required.

🔑

Passkeys

WebAuthn support via the system's platform authenticator — sign in with Touch ID where sites support it.

⚙️

Real settings

Toggle ad blocking, clear cookies and cache, set a custom homepage — all wired to working functionality.

📋

Live logs

An in-app log viewer streaming real activity from the ad blocker, PiP, and DevTools as it happens.
