Site Blocker

About

🚀 Stay Focused with the Site Blocker Extension
SiteBlocker is a modern extension for Chrome designed to help you block websites and stay productive throughout the day. If you are searching for how to block sites on Chrome or need a reliable browser extension to control distracting content, this app offers flexible website access with a clean and intuitive experience.

🛡️ Two Modes for Website Blocking
🟢 Simple Mode
Simple Mode allows you to quickly block distracting websites without passwords or confirmations. This mode is ideal for users who want a lightweight productivity extension to control social media, entertainment platforms, or other time-wasting sites. You stay in control of your time but can always adjust rules when your routine changes.

🔒 Strict Mode
Strict Mode adds password-protected of extension. Once enabled, you cannot disable blocking, remove a site, or change schedules without authorization. This makes the extension suitable for strict productivity control, parental control on Chrome, and long-term habit building, when you want stronger protection from impulsive tab opening and endless scrolling.

🚫 Smart Website Blocking
With the extension, you can:

Block websites by domain or subdomains

Redirect blocked websites to a motivation page

Instantly block the current site from the browser

Prevent access to blocked sites in real time

This approach helps block social media sites, adult content, and reduce online distractions while keeping control transparent. It works well both for single problematic sites and for large lists of resources that steal attention during the day.

📂 Categories and Group-Based
Organize access to websites into categories such as:

Social Media

Entertainment

Games

Work

Category-based management allows this Chrome extension to block multiple sites at once and apply shared rules more efficiently. You can maintain separate control strategies for work, study, and free time, instead of constantly editing long individual blocklists.


⏰ Per-Site Blocking Schedule
Block specific websites at selected times, such as video platforms during work hours or messengers during deep-focus sessions.

📆 Category Blocking Schedule
Apply access rules to entire groups. For example, block all distracting websites from Monday to Friday, 9:00–18:00, and leave them available in the evening or on weekends.

🎨 Visual Weekly Editor
Manage access periods using a visual weekly planner with clear time slots. This makes it easy to see when each site or category is available and quickly adjust your routine without digging through complex settings.

🎯 Built for Productivity and Focus
The SiteBlocker extension is useful if you are looking for:

Many users also search how do you block a site on Safari. While SiteBlocker is a Chrome extension, it follows the same website blocking principles used across modern browsers, so the mental model easily transfers between devices and platforms.

🧩 Clean Design and Native Experience
Designed with Google Material Design 3, SiteBlocker offers a modern interface that feels native to Chrome. No clutter, no unnecessary steps — only clear website blocking and focus control. The layout is optimized for quick actions, so you can add a site to the blocklist or adjust a schedule in just a few clicks without being distracted by complex menus.
