Cold Turkey Blocker is a desktop application for Mac and Windows that blocks distracting websites, apps, and even your entire computer with near-impossible bypass resistance. Unlike browser extensions you can disable in seconds, Cold Turkey enforces blocks at the system level, surviving uninstall attempts, restarts, and workarounds. The free version blocks websites on a timer; the Pro version ($45 one-time) adds app blocking, scheduling, and the nuclear "Frozen Turkey" mode that locks down your entire machine.

Key takeaways:

• Cold Turkey Blocker blocks websites, apps, and your entire computer with the strictest enforcement available on desktop
• Free version blocks websites; Pro ($45 one-time) adds application blocking, scheduling, Frozen Turkey mode, and advanced locking
• System-level blocking survives uninstall attempts, browser switches, restarts, and most workarounds
• No subscriptions or data collection, pay once, own forever, all settings stored locally
• Best for writers, students, and professionals who need absolute enforcement, not gentle nudges

What Is Cold Turkey Blocker?

Cold Turkey Blocker is a productivity tool designed to block digital distractions on Mac and Windows. It blocks websites in all browsers, desktop applications (games, social media apps, streaming apps), and can lock down your entire computer during focus sessions.

The software has been downloaded millions of times and holds a 4.6-star rating across thousands of user reviews. It's widely regarded as the most difficult-to-bypass blocker on any platform, earning it a cult following among writers on deadline, students during finals, and anyone who's defeated softer blocking tools.

Cold Turkey was created by developer Felix Belzile as a one-time-purchase alternative to subscription-based blockers. The pricing model is straightforward: the free version blocks websites, and the Pro upgrade ($45) unlocks all features for life on every computer you own.

How Cold Turkey Blocker Works

Cold Turkey Blocker operates at the system level, not just in your browser. When you install the desktop app on Mac and Windows, it installs browser extensions for Chrome, Firefox, Edge, and other supported browsers. These extensions communicate with the local background app, which enforces blocks even if you disable the extension, switch browsers, or restart your computer.

Once a block is locked, the app prevents:

• Uninstalling Cold Turkey
• Disabling the browser extension
• Editing the hosts file to bypass blocks
• Changing system time/date to workaround timers
• Force-quitting the blocking process

This persistence is what sets Cold Turkey apart from browser-only blockers. According to a 2019 Cambridge University meta-analysis, problematic internet use is associated with significant cognitive deficits in attentional inhibition and decision-making. Cold Turkey removes the decision entirely, you can't override the block until the timer expires.

The blocking mechanism uses multiple enforcement layers:

1. Browser extensions intercept and block URLs in real-time
2. Desktop app monitors running processes and kills blocked applications
3. Registry/system hooks (Windows) or kernel extensions (macOS) prevent tampering
4. Network-level filtering for advanced blocking modes

All blocking rules and statistics are stored locally on your device. Cold Turkey never collects or transmits your browsing data.

Cold Turkey Blocker Features

Cold Turkey packs a comprehensive feature set into a surprisingly simple interface. Here's what you can block and how.

Website Blocking

The free version includes full website blocking across all browsers. You can:

• Block entire domains (reddit.com blocks all Reddit pages and subdomains)
• Block specific URLs (reddit.com/r/funny blocks only that subreddit)
• Block YouTube channels by URL
• Block search queries containing certain keywords using wildcards
• Block the entire internet by adding *.* and then whitelisting only the sites you need
• Block all adult websites and content with a single wildcard rule (*.xxx)

Cold Turkey ships with pre-made block lists (social media, shopping, news, gaming) you can import and customize. The block page displays a motivational message when you try to visit a blocked site, reminding you to get back to work.

One unique feature: Pause for a Cause lets you donate to the World Wildlife Fund for a 10-minute break. It's optional and can be disabled, but it adds friction to bypass attempts while supporting conservation.

Application Blocking (Pro)

The Pro version blocks desktop applications alongside websites. You can add:

• Executable files (.exe on Windows, .app on macOS)
• Entire folders (blocks all apps in that location)
• Microsoft Store apps (Windows only)
• Window titles (useful for blocking specific windows in an app)

This is critical for blocking distractions that live outside the browser: Steam, Discord, messaging apps, mobile game emulators, or any other time sink on your computer. If you can launch it, Cold Turkey Pro can block it.

Frozen Turkey Mode (Pro)

Frozen Turkey is Cold Turkey's nuclear option. It doesn't block specific sites or apps, it blocks your entire computer.

When a Frozen Turkey block activates, you can choose to:

• Lock the screen (requires password to unlock, but block persists)
• Log off (ends your session)
• Shutdown (turns off the computer)

This mode is designed for scheduled breaks. Set Frozen Turkey to lock your computer every 90 minutes for a 10-minute walk, or schedule automatic shutdowns at night to enforce a sleep routine. It helps you improve focus by forcing time away from your device.

It's extreme, but effective. One user review on the Chrome Web Store called it "the most locked-down and difficult to circumvent that I've found."

Locking & Scheduling

Cold Turkey's real power is in locking mechanisms that prevent you from disabling the block. You can lock a block with:

• Timer: block persists until a future time (you can extend, but not shorten)
• Time range: only allow changes during specific hours/days
• Random text: type 50-5000 randomized characters to unlock
• Delay: wait 1 minute to 40 days before unlocking
• Password: require a password (useful for accountability partners or parents)
• Restart: require a full computer restart to unlock
• Schedule lock: prevent changes during or before scheduled blocks

The scheduled blocks feature (Pro) lets you click and drag on a weekly calendar to set recurring blocks. The schedule auto-repeats every week. Set it once, block Reddit and YouTube every weekday from 9 AM to 5 PM, and forget it.

Cold Turkey also supports flexible break modes:

• Pomodoro (work 25 minutes, break 5 minutes, repeat)
• Allowance (use blocked sites for 30 minutes per day, refills daily/weekly/monthly)
• Reward (earn breaks by working; breaks expire at the end of each period)
• Sessions (allow a set number of visits per day/week)

These let you limit time on distractions instead of blocking them entirely.

Statistics & Privacy

Cold Turkey tracks which websites and apps you visit, how long you spend on them, and when. The statistics panel shows your top distractions over custom date ranges, helping you see patterns and adjust your block lists. Copy the data to analyze trends or expand your blocking strategy as you discover new time sinks.

Critically, all statistics are stored locally on your computer. Cold Turkey's privacy policy states clearly: "Your settings and statistics are stored locally on your device. We can't access them, even if we try." There are no accounts, no cloud sync, no data collection. You can export your stats as JSON or delete them entirely.

For users concerned about digital privacy, this is a major differentiator. Competing blockers like Freedom require accounts and sync data across devices, convenient, but not private.

Cold Turkey Pricing: Free vs Pro

Cold Turkey Blocker Free:

• Block websites in all browsers

How Cold Turkey Pricing Compares

Compared to subscription-based blockers, Cold Turkey saves money over time:

If you plan to use a blocker for more than one year, Cold Turkey's one-time fee is cheaper than any subscription. If you need cross-device sync (phone, tablet, laptop), Freedom or LockIn MCP might be better fits, but for pure desktop blocking, Cold Turkey is unmatched.

Cold Turkey Blocker vs Alternatives

Cold Turkey occupies a specific niche: the strictest, most unbypassable desktop blocker available. Here's how it compares to alternatives.

Cold Turkey vs Freedom

Freedom is a cross-platform blocker (Mac, Windows, iOS, Android, Chrome) with cloud sync. It's easier to use and works on mobile, but it's less strict and requires a subscription.

• Blocking severity: Cold Turkey is harder to bypass
• Platforms: Freedom covers mobile; Cold Turkey is desktop-only
• Pricing: Freedom $39.99/year vs Cold Turkey $45 once
• Sync: Freedom syncs across devices; Cold Turkey is local-only

Choose Freedom if you need mobile blocking. Choose Cold Turkey if you need the strongest desktop enforcement and hate subscriptions. Read our full LockIn MCP vs Freedom comparison for more context.

Cold Turkey vs LockIn MCP

LockIn MCP is a newer system-level blocker that integrates with AI assistants (ChatGPT, Claude, Poke) via the Model Context Protocol. It blocks websites at the OS level (hosts file + MCP server) and lets you start focus sessions by asking your AI assistant.

• Blocking method: Both use system-level enforcement
• Integration: LockIn connects to AI tools; Cold Turkey is standalone
• Pricing: LockIn $2.99/month or free tier; Cold Turkey $45 once
• AI control: LockIn lets AI manage blocks; Cold Turkey uses schedules and timers

Choose LockIn if you already use AI assistants and want AI-native productivity coaching. Choose Cold Turkey if you want a mature, battle-tested blocker with a proven track record. See our detailed LockIn MCP vs Cold Turkey breakdown.

Cold Turkey vs Browser Extensions

Browser-only blockers (BlockSite, StayFocusd, LeechBlock) are free and easy to set up, but trivial to bypass, just disable the extension, switch browsers, or use incognito mode.

Cold Turkey's system-level enforcement is leagues ahead. If you've defeated browser extensions in the past, Cold Turkey is the upgrade you need. Read our guide to the best system-level website blockers for more comparisons.

Who Should Use Cold Turkey Blocker?

Cold Turkey is not for everyone. It's strict, unforgiving, and designed for people who need absolute enforcement.

Use Cold Turkey if:

• You've defeated softer blockers in the past (browser extensions, willpower-based tools)
• You need to enforce deep work on desktop (writing, coding, studying, research)
• You prefer one-time purchases over subscriptions
• You value privacy and want local-only data storage
• You need the nuclear option (Frozen Turkey mode to lock down your entire computer)

Don't use Cold Turkey if:

• You need mobile blocking (phone, tablet), Cold Turkey is desktop-only
• You want gentle nudges instead of hard enforcement
• You need cross-device sync, Cold Turkey doesn't sync settings between computers
• You prefer cloud-based tools, everything is local

Cold Turkey is popular among:

• Writers on deadline who need to block everything but their word processor
• Students during exam periods who need unbreakable focus
• Developers who want to block GitHub, Hacker News, and Stack Overflow during deep work
• Anyone recovering from internet/gaming addiction who needs external enforcement

One Chrome Web Store reviewer wrote: "Cold Turkey Blocker has, in some ways, saved my life... in this day and age of monthly fees, he charges a one-time fee and continues to support the app and make improvements."

How to Install Cold Turkey Blocker

Getting started with Cold Turkey takes about five minutes to install and configure on Mac and Windows.

Step 1: Download the installer

Visit getcoldturkey.com/pricing and download the installer for Windows or macOS. The free version includes a 7-day trial of all Pro features, no credit card required.

Step 2: Install the desktop app

Run the installer and follow the prompts. The app installs a background service that runs on startup. The install process is quick, typically completing in under two minutes.

Step 3: Install browser extensions

After installing the desktop app, Cold Turkey will prompt you to install browser extensions for Chrome, Firefox, Edge, and other supported browsers. Click the links to add them. This step is required to block social media sites and other web content.

Step 4: Create your first block

Open Cold Turkey, click "Add Block," and add websites or apps to block. Set a timer, choose a lock type (or skip locking for testing), and click "Start."

When a block is active, you'll see a block page when you try to visit a restricted site. If you locked the block, you won't be able to stop it until the timer expires or you complete the unlock condition (typing random text, waiting through a delay, etc.).

Pro tip:Start with short, unlocked blocks to test your settings before locking yourself out for hours. For a complete walkthrough, see our guide on how to block websites on Windows.
