FocusKeeper is a free Chrome add-on designed to help users block distracting websites and enhance productivity. By allowing users to customize their browsing experience, the extension provides two primary modes: Blacklist Mode, which blocks addictive sites and social media, and Whitelist Mode, which permits access only to essential websites. This flexible approach caters to different productivity needs, making it easier for users to focus on their tasks without the interference of time-wasting distractions.

The extension also features custom tab limits, enabling users to manage their online activities more effectively. Users can set limits on how many tabs can be open for sites like YouTube, allowing for background music or podcasts without the risk of getting sidetracked. With one-click blocking, real-time focus overviews, and the ability to easily disable the extension, FocusKeeper empowers users to take control of their online habits and prioritize their time more efficiently.
