TabColor is a free Chrome add-on developed by takedajs. It allows you to customize the appearance of your browser tabs by changing their color based on specific keywords. By registering multiple keywords, you can make the left end of the browser turn red whenever the URL matches any of the specified keywords.

Currently, TabColor is still under development, and the plan is to make the entire tab turn red instead of just the left end of the browser. This feature will provide a more visually striking customization option for users who want to personalize their browsing experience.

With TabColor, you can easily add a touch of color to your browser tabs, making it easier to differentiate between different websites or categories of content. Stay tuned for future updates as TabColor continues to evolve and expand its customization options.
