Habit Killer is a free Chrome add-on developed by Bjorn the Programmer. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. Designed to help users regain control of their lives, Habit Killer aims to increase productivity on the web by blocking access to time-consuming websites.

With Habit Killer, you can easily block sites like Twitter, Facebook, or Google that often serve as distractions. The add-on ensures that whenever you attempt to access a blocked site, you are met with a negative stimulus. The blocked site is covered with a bright, annoying background, making it difficult to read the text or engage in any activities on the site. This visual deterrent forces you to resist the temptation and stay focused on your tasks.

By implementing Habit Killer, you can eliminate social media and gaming distractions, allowing you to reclaim control of your online habits and ultimately improve your productivity. With its straightforward interface and effective blocking mechanism, Habit Killer is a valuable tool for those looking to optimize their time spent on the web.
