SiteBlocker — Focus & Website Blocker

Block distracting sites on schedule, with strict or mindful mode. Zero data collection.

SiteBlocker — Website Blocker & Focus Timer Stop procrastinating and unlock deep focus. SiteBlocker is the ultimate privacy-first Chrome extension designed to block distracting websites, automate productivity schedules, and build long-term work habits. Whether you are a developer writing code, a student studying for exams, or a creator looking to reclaim your attention span, SiteBlocker gives you the tools to filter out digital noise and stay in flow. Built entirely on Chrome’s modern, high-performance Manifest V3 network architecture, SiteBlocker runs at the browser level. This guarantees zero lag, near-zero CPU and memory usage, and 100% on-device data privacy. 🚀 CORE FEATURES 1. DYNAMIC WEBSITE BLOCKING (Free) Instantly block any distractive domain (e.g., youtube.com, reddit.com, twitter.com) with a single click. Our dual-layer blocking engine intercepts requests at both the network stack and client-side page load, ensuring that Service Worker caches and Progressive Web Apps (PWAs) cannot bypass your block. 2. DYNAMIC PRESSETS & CATEGORIES Block entire groups of distracting websites instantly. Use pre-defined categories (such as Social Media, Video Streaming, Gaming, Adult Content) or build your own custom lists to block multiple domains in one go. 3. SMART DAILY USAGE LIMITS (PRO) Enforce time limits on specific websites. Set a daily allowance (e.g., 15 minutes of Instagram per day). A visual circular progress ring next to the domain name displays exactly how much time you have left, automatically locking the site once your limit is reached. 4. AUTOMATED FOCUS SCHEDULES (PRO) Set repeating schedules (e.g., Mon-Fri, 9:00 AM - 5:00 PM) to automate your blocking rules. Configure schedules by day, hour, and timezone, with date overrides for holidays and vacations. SiteBlocker automatically locks down your list during work hours and unlocks it when you are done. 5. STRICTOR FOCUS & PIN LOCK (PRO) Need absolute discipline? Enable Strict Mode to lock your blocklist, options dashboard, and settings behind a secure 4-digit PIN password. This prevents you from impulsively disabling the blocker, editing rules, or deleting domains when your willpower is low. 6. MINDFUL MODE INTERSTITIAL (PRO) Introduce deliberate friction. Instead of a hard block page, Mindful Mode triggers an 8-second breathing pause, prompting you to breathe and reflect on whether you truly need to visit a site. Continue to the target page only after the timer completes. 7. POMODORO FOCUS SESSIONS (PRO) Start timed focus sprints (25, 45, or 60 minutes) or run a stopwatch to track your deep work time. Active focus session countdowns are rendered directly on blocked pages to keep you motivated. 8. CLOUD CONFIG SYNC & GOOGLE DRIVE BACKUP (PRO) Securely backup your configuration (blocklists, schedules, and settings) directly to your Google Drive AppData folder. Restoring your settings on a new device takes one click, keeping your data private and independent of third-party servers. 🛡️ PRIVACY & EFFICIENCY FIRST Zero Data Tracking: We respect your privacy. SiteBlocker does not log, track, or collect your browsing history, searches, or credentials. All settings, logs, and rules are encrypted and stored 100% locally on your machine. XOR Storage Encryption: Sensitive configuration keys and options are encoded locally to prevent simple manual tampering in browser local files. Lightweight & Battery-Friendly: Because it utilizes native Chrome declarativeNetRequest APIs, SiteBlocker operates seamlessly in the background without draining your laptop's battery or slowing down your browser tabs. 🎯 WHO IS SITEBLOCKER FOR? Software Engineers: Eliminate tabs like Hacker News, Reddit, or YouTube while debugging or coding. Students: Block social media during study sessions and exam preparation. Writers & Creators: Focus on the blank page without being drawn away by notifications or viral threads. Remote Workers (WFH): Set automated schedules to separate work hours from personal time.
