Cold Turkey Alternatives for Linux: 8 Website & App Blockers

Linux users have multiple alternatives to Cold Turkey for blocking distractions. Tools like DigitalZen, Freedom, Chomper, Pluckeye, Twert, Time Companion, SelfControl Linux Port, and LeechBlock provide various options for website and app blocking, helping users stay productive across different Linux setups and technical skill levels.

 

Why Linux Users Need Cold Turkey Alternatives

Since Cold Turkey does not support Linux, users need a reliable Linux alternative to manage distractions and stay focused. Unlike Windows and Mac, Linux users have fewer options for a tool that blocks websites and provides comprehensive productivity control.

An effective Linux website blocker should handle both site filtering and desktop applications, work across multiple distributions, and deliver reliable restrictions that cannot be easily bypassed.

1. DigitalZen

DigitalZen Linux Website Blocker is one of the few tools that truly supports Linux desktops with full app blocking capabilities. Unlike other tools that only work through browser extensions, DigitalZen provides a native desktop agent for Linux, alongside Windows and Mac.

The platform combines website blocking, desktop app blocking, and mindful screen time management. Users can set daily limits on websites or desktop apps, block them entirely, or rotate blocking times. The Focus Mode lets you select apps and websites to focus on or block everything, set a timer, and start achieving your goals.

Features

• Simple Setup: Easy to install and configure with no technical skills required. Users can select apps and websites from a list instead of manually entering file paths or complex URL patterns.
• Multiple Adaptive Locks: Includes several ways to stay disciplined, such as:
  • Code: Requires entering a long, generated code to unlock,  giving you time to reconsider.
  • Cooldown: Starts a timer before unlocking to prevent impulsive decisions.
  • Friend: Sends an unlock code to a chosen friend’s email for accountability.
  • Schedule: Locks access until a future date you set yourself.
  • Money: Adds a small financial penalty to discourage frequent unlocking.

• • Lock Screen Reminders: Display helpful messages like “stretch and drink coffee” while distractions are blocked.

Chomper is an open-source internet blocker for Linux, created to help users prevent procrastination and mindless web surfing. The developer built it after noticing that existing blockers like Cold Turkey or SelfControl did not support Linux, and other similar projects had been inactive for years.

Unlike most programs that modify the hosts file to block entire domains, Chomper uses a transparent proxy to filter outgoing requests. This allows users to block specific URLs or pages (for example, amazon.com/gp/video/) while keeping access to other parts of the same site.

Features

• Platform: Linux (supports all distributions; automated installation for Debian-based systems)
• Interface: Command-line interface (CLI)
• Blocking Method: Transparent proxy to filter outgoing requests
• Granular Control: Can block specific pages or paths, not just domains
• Blacklist/Whitelist Options: Can either block distracting websites or allow only productive ones
• License: GPL-licensed (open source)
• Documentation: Full documentation available on ReadTheDocs

Installation

• For Debian-based systems (Ubuntu, Linux Mint)

The script installs all UNIX dependencies, installs pyenv, installs Python 3.6.4 in ~/.pyenv/ subdirectory, clones Chomper into ~/chomper, and appends a Chomper executable to your PATH.

• For non-Debian-based distributions:

No automated installation available. The documentation suggests looking at the automated installation script for guidance.

Pricing

Free and open source under the GPL license.

Disadvantages

• Requires Command-Line Knowledge

• • No graphical interface (CLI-only)
  • Users must run commands and edit settings manually

4. Pluckeye

Image source: Pluckeye official website

Pluckeye is a self-control internet filter that helps users manage their online habits by making changes take effect only after a delay. Instead of relying on passwords, it uses a waiting period before new settings are applied, giving users time to reconsider impulsive decisions.

By default, Pluckeye blocks all images and videos from the internet to minimize distractions. Users can then create their own filtering rules, allowing or blocking specific URLs or media types. This design gives the user full control while remaining difficult to circumvent: a combination the developers call self-control mode.

Features

• Platform Support: Pluckeye is available on Windows, macOS, Linux, and has an alpha version for Android.
• Delay System: Instead of relying on passwords, Pluckeye uses a configuration delay system that enforces a waiting period before changes take effect. This makes it harder to impulsively disable the filter.
• Self-Control Mode: The software is designed to give users full authority over what gets filtered while maintaining resistance to circumvention, supporting genuine self-control.
• Content Filtering: It can selectively block or allow specific types of content from the same website, using filters based on internet media types or individual URLs.
• Default Blocking: By default, Pluckeye blocks all online images and videos to minimize visual distractions and exposure to unwanted media.
• No Prepackaged Lists: The tool does not include preset blocklists; instead, users create their own filtering rules tailored to their habits and goals.
• Design Philosophy: Pluckeye is intentionally designed to be inconvenient, reinforcing deliberate and mindful internet use rather than ease of access.

Installation

Pluckeye supports Linux and provides a manual installation process through the terminal.

• Visit r.pluckeye.net/try-it and download the Linux installer file (e.g., pluckeye-linux-1.0.63.tar.gz).

Open a terminal and run the following commands:

cd /tmp

rm -f ./pluck*install*

for tarball in $HOME/Downloads/pluck*.tar*; do echo $tarball; done

tar xf $tarball

sudo ./plucky-install

• If you see the message “Plucky failed to download” on Debian-based systems, run:
  
  sudo apt-get install libcurl4

sudo ./plucky-install

• Additional instructions are available for updating or uninstalling Pluckeye directly on the official website.

Pricing

Pluckeye follows a sliding-scale subscription model. The exact amount depends on the user’s annual income. While pricing details are not publicly listed, users are encouraged to download, install, and use the software for a few days before deciding whether to pay.

The website mentions that payment is optional at first, and users can later choose to remunerate (support) the project once they’ve tried it. There is also a field for coupon codes, suggesting flexible or discounted payment options.

Disadvantages

• Complex Setup and Manual Configuration

• • Installation requires running multiple terminal commands.
  • Users must manually create and manage filtering rules.

• No Graphical Interface

• • Pluckeye is configured through commands and settings files.
  • There is no easy point-and-click interface for non-technical users.

Frequently Asked Questions

Can These Tools Really Replace Cold Turkey on Linux?

Yes, several tools can serve as alternatives, but their effectiveness varies. Some, like Chomper and Pluckeye, offer focused but limited control. DigitalZen, however, provides the closest full replacement, combining website and app blocking, adaptive locks, and scheduling features built specifically for Linux users.

Do I Need Technical Skills to Use These Blockers?

DigitalZen is designed for all users and doesn’t require any technical knowledge to install or configure. Chomper, on the other hand, needs sudo privileges and basic command-line experience since it’s operated through a terminal. Pluckeye’s technical requirements aren’t clearly specified in the available documentation.

How Do These Blockers Prevent Cheating?

DigitalZen includes adaptive lock options that make it harder to stop a block or change settings too easily, offering different lock types depending on how much friction the user needs. Chomper enforces discipline by requiring sudo access for modifications, while Pluckeye’s delay system ensures that any configuration changes take effect only after a set waiting period.

Is the DigitalZen Desktop Agent Mandatory?

The desktop agent isn’t required to use DigitalZen, since you can run it directly in your browser. However, browser-only functionality is limited. Installing the desktop app unlocks full features like application blocking and advanced focus controls.
