ZFocus – Pomodoro & Focus Zones

ZFocus is a privacy‑first browser extension that blocks distracting websites based on user‑defined schedules, limits, and smart exception patterns. It lets you create Pomodoro‑style focus zones, specify active‑tab only blocking, and set time‑based rules such as “5 minutes every hour.” The extension can automatically close tabs that match a block list or redirect them to productive destinations, and it offers built‑in break timers of 3, 5, or 10 minutes.

The tool is aimed at individuals who want to reduce online interruptions while keeping their browsing data local. By storing all configurations in the browser and avoiding any remote tracking, it appeals to users concerned with privacy. Its UI supports light and dark themes, multiple languages, and works on Chrome, Firefox, and other major browsers.

Distinctive features include exception‑pattern blocking (e.g., allowing specific YouTube channels while blocking the rest), automatic tab closure with dashboard fallback, and visual statistics of time saved. The project is open source and currently in an experimental maturity stage.
