Advanced Website Blocking
Take complete control of your browsing with powerful website blocking features. Block distracting sites, allow only productive websites, or use keywords to block entire categories.
Three Powerful Blocking Modes
Blocklist Mode - Block Specific Websites
Add specific websites to your blocklist to prevent access during work or study time. Perfect for blocking social media platforms like Facebook, Twitter, Instagram, TikTok, Reddit, or entertainment sites like YouTube, Netflix, and gaming platforms.
- Add unlimited websites to your blocklist
- Block with wildcards (e.g., *.reddit.com blocks all Reddit domains)
- Instant blocking - sites become inaccessible immediately
- Easy management - add or remove sites anytime
Whitelist Mode - Allow Only Approved Sites
For maximum focus and parental controls, use whitelist mode to allow access only to pre-approved websites. Everything else is blocked by default. Ideal for students during exam preparation or creating safe browsing environments for children.
- Block everything except approved websites
- Perfect for extreme focus sessions
- Great for parental controls and child safety
- Quickly switch between blocklist and whitelist modes
Smart Keyword Blocking
Block entire categories of websites with keyword-based blocking. Add keywords like "social", "shopping", or "gaming" to automatically block all matching websites. Save time by blocking categories instead of individual sites.
- Block categories with single keywords
- Example: "social" blocks Facebook, Twitter, Instagram automatically
- Intelligent matching for comprehensive coverage
- Combine with blocklist for fine-tuned control
