Defer

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.
