Sentinel: Redirect & Pop-up Blocker

Stops forced redirects, tracker-laundered redirect chains, pop-ups, tab-jacks, back-button traps and notification spam. All local.

Sentinel is a local-first blocker for the web's most annoying and abusive behaviors. WHAT IT STOPS • Forced redirects and tracker-laundered redirect chains • Pop-ups and pop-unders • Tab-jacking and back-button/history traps • Fake "install this to continue" dialogs and ad overlays • Notification, location, camera and mic prompt spam • Crypto-miners, tracking beacons, and known ad/analytics hosts • Drive-by (no-click) downloads HOW IT'S DIFFERENT • A live "monitoring console": a radar and an interception log show exactly what was stopped, in real time. • Everything runs on your device. No analytics, no telemetry, no tracking of you. • Per-site controls: turn individual blockers on or off for one site. • Bring your own filter list: import EasyList or any uBlock-style list. FREE vs PRO Every blocker is free and always will be. Pro adds depth: full history and search, insights, filter-list import, the custom rule engine, per-site options, schedules, and the rule audit. Cancel a subscription any time to stop future billing. Sentinel makes no outbound network request except to verify a Pro purchase.
