Warden

Free blocker that blocks all sites and new tabs by default. Only whitelisted sites get through.

Warden flips the script on website blockers. Instead of blocking a few distracting sites, Warden blocks everything, every website and every new tab, by default. Completely free, no premium tiers, no limits. You decide which sites are allowed. Features: - Whitelist-based blocking — all websites and new tabs are blocked unless you explicitly allow them - Subdomain support — whitelisting a domain automatically allows all its subdomains - Per-site new tab control — choose whether each allowed site can open new tabs - Pause blocking — temporarily disable protection for 1 minute, 10 minutes, 30 minutes, 1 hour, 1 day, or indefinitely - PIN protection — set a PIN to prevent impulsive changes to your settings - Clean, dark-themed interface - 100% free with no data collection — everything stays in your browser Perfect for deep work sessions, studying, or anyone who wants to limit their browsing to only what matters.
