ZenBlock

ZenBlock is a Chrome extension for blocking distracting websites and reducing time spent on social media and doomscrolling. It is described as a simple browser-based tool for deep work, with no account required to get started.

Its features center on interrupting impulsive browsing and creating scheduled focus time. Strict Mode makes blocked sites impossible to cancel once active. Wait Mode adds a 30-second breathing pause before access. Scheduling can automatically block sites during work hours, and the focus timer provides Pomodoro-style sessions in the browser. ZenBlock also includes Cloud Sync for blocklists and schedules across computers and Analytics for visualizing browsing habits. The page also describes mindful friction, intended to turn scrolling into more deliberate choices.

The product is aimed at people who want to focus, complete deep work sessions, and avoid constant context switching. It is also presented as privacy-first: the FAQ says blocking decisions happen locally on the user’s computer and that browsing history is neither collected nor sold.

ZenBlock is available as a Chrome extension, with an install flow that says it can be added to the browser in one click. Pricing is described as a simple plan structure: a free version includes core blocking features and the focus timer, while ZenBlock Pro is a lifetime access plan with a one-time payment, unlimited websites, unbreakable Strict Mode, unlimited focus schedules, a custom pause timer, deep focus insights, sync across devices, priority support, and future updates. A 30-day refund policy is also stated.
