Defer

Block distracting websites with a commitment device lockout mode.

Defer helps you take back your attention by letting you block any website you choose. Add a domain, and it's blocked immediately — redirecting you to a calm reminder page instead. What makes Defer different is Lockout Mode. Once enabled, any changes to your blocklist — adding or removing sites — are delayed by 20 minutes before taking effect. That delay is enough to outlast the impulse that sent you reaching for a distraction in the first place. Features: • Block any domain instantly • Custom blocked page with a motivational reminder • Lockout Mode: 20-minute delay on all blocklist edits • Pending changes visible with live countdown timers • Cancel a pending change before it applies • Enable/disable blocking globally with one toggle • Works across Chrome, Edge, and Firefox Defer doesn't collect any data, connect to any server, or track anything about your browsing. Your blocklist lives on your device only.
