Infinite scroll is a bug. This is the patch.
Hide YouTube Shorts, Instagram & Facebook Reels, and block TikTok — right in Safari. Free. No accounts. No tracking.
Slowth removes the infinite-feed traps while leaving the rest of each site usable. You don't have to delete anything; you just lose the black hole.
- Hides Shorts / Reels on YouTube, Instagram, Facebook, X and blocks TikTok entirely.
- Per-site control — for each site, pick one of three states.
- Strict mode — a 24-hour lock. Once on, you can't loosen your own settings until it expires. Survives app restart and reboot; the only bypass is uninstall + reinstall.
- Family Controls (iOS) — optionally block the native apps too, not just the web.
- Remote blocking rules — CSS selectors and redirects load from a remote config and are cached on-device, so breakage from a site redesign gets fixed without shipping an app update.
| Site | Modes | Default |
|---|---|---|
| YouTube | off / shorts only / block | shorts |
| off / shorts only / block | shorts | |
| off / shorts only / block | shorts | |
| X | off / shorts only / block | shorts |
| TikTok | off / block | block |
- off — do nothing.
- shorts only — hide the short-video surfaces and redirect their URLs.
- block — redirect the whole site to a local blocked page.
Two UI surfaces on top of one shared store:
- Host apps (iOS + macOS) — a single SwiftUI codebase drives the settings directly. No web view, no JS bridge.
- Safari Web Extension popup — talks to the extension's native handler over native messaging.
The source of truth is App Group UserDefaults, shared across all four
targets (macOS app, iOS app, and both Safari extension targets). The
extension's background script uses webNavigation as a tri-state
dispatcher: off → no-op, shorts → inject hide-CSS + URL redirects,
block → redirect the tab to a local blocked page. Blocking rules are
versioned, fetched with an ETag and a throttle, and refreshed on a 6h alarm.

Slowth stores your settings on-device in an App Group container and fetches public blocking rules over HTTPS. It has no backend, no analytics, and never sends your browsing anywhere. On iOS, the list of apps you choose to block is held by the OS in a privacy-protected token that the app itself cannot read.
