Boost Your Productivity: A Guide to the Best Open Source CLI Time Trackers
For developers, system administrators, and anyone who lives in the terminal, minimizing distractions is the key to deep, productive work. Every time you switch contexts—moving from your code editor to a browser tab to start a timer—you lose a small piece of your focus. That’s where Command-Line Interface (CLI) time trackers come in.
These lightweight, powerful tools integrate directly into your existing workflow, allowing you to manage your time without ever leaving the keyboard. They are fast, scriptable, and incredibly efficient. If you’re looking to streamline your process and gain better insight into your work habits, a CLI time tracker is an essential tool.
Here’s a look at some of the best free and open source options available today.
Why Choose a Command-Line Time Tracker?
Before diving into the tools, it’s worth understanding the advantages of a CLI-based approach:
- Zero Distractions: No graphical user interface (GUI) means no unnecessary buttons, animations, or notifications to pull you out of your flow state.
- Speed and Efficiency: Launching a command is almost instantaneous. You can start, stop, and log tasks with a few keystrokes.
- Automation and Scripting: CLI tools are easily scriptable, allowing you to integrate them with Git hooks, shell scripts, or other developer tools to automate your time tracking.
- Lightweight Performance: These applications use minimal system resources, so they won’t slow down your machine, no matter how many other processes you have running.
- Complete Control: Your data is typically stored in simple, human-readable text files (like JSON or plain text), giving you full ownership and control over your information.
Top-Tier CLI Time Trackers for a Focused Workflow
While there are dozens of options available, a few stand out for their robust features, excellent documentation, and active communities.

Watson: Simplicity and Elegance
If Timewarrior is a comprehensive suite, Watson is its minimalist, elegant counterpart. It prioritizes ease of use and a clean, straightforward command set. Starting a timer is as simple as watson start my-project +some-tag.

How to Choose the Right CLI Time Tracker for You
With so many options, selecting the right one depends on your specific needs. Ask yourself these questions:
- What is my primary goal? Am I just tracking time for personal productivity, or do I need detailed reports for invoicing clients? For simple tracking, a tool like Watson is perfect. For complex reporting, Timewarrior is superior.
- Do I need integrations? If you live in Taskwarrior, Timewarrior is the natural choice. If you need to connect with Jira or GitHub, Super Productivity is a strong contender.
- How important is simplicity? If you want a tool you can master in five minutes, look for one with a minimal command set.
- What format do I want my data in? Most tools use plain text or JSON, which is great for portability and control. Ensure the format works for any custom scripts you might want to write.
Actionable Tips for Effective Time Tracking
To get the most out of your new CLI time tracker, incorporate these best practices:
- Create Shell Aliases: Speed up your workflow by creating short aliases for common commands. For example,
alias tin="watson start"andalias tout="watson stop"can save you valuable keystrokes. - Automate with Git Hooks: Set up a pre-commit Git hook that reminds you to start a timer if one isn’t already running. This ensures you never forget to track your work on a new feature.
- Regularly Review Your Reports: Set aside a few minutes at the end of each day or week to run a report. This simple habit will help you identify time-wasting activities, understand where your efforts are going, and make better decisions about how you manage your schedule.
By moving your time tracking to the command line, you can reclaim your focus, reduce distractions, and gain powerful, data-driven insights into your own productivity. Choose a tool that fits your workflow, stick with it, and watch your efficiency soar.
