LockIn - Website Blocker for Focus & Productivity

LockIn — block distracting websites and stay focused. 100% free, no account needed.

LockIn is a focus extension for people who are serious about stopping doom scrolling. Pick your distraction sites, flip LockIn on, and those tabs get hard-redirected to a blocked page that reminds you what you're burning. No soft nudges, no "are you sure?" popups — just a clean, brutal lock. Behind that simplicity is a full focus system. LockIn tracks how many times it saves you, estimates the time you've reclaimed, and turns it into XP, levels, streaks, and achievements so you can actually see your progress over days and weeks. There's a weekly report, an achievements page, and a new tab view showing your current level and total time saved. You stay in control. Add your own custom distraction sites and toggle built-in presets. Use quick Pause and Focus session buttons when you genuinely need a break or a deep-work block. One-click Context Packs cover common setups — Student Mode, Founder Mode, ADHD Focus, Exam Mode, and No AI. Set a daily schedule so blocking only runs during work hours, add path exceptions for specific URLs, and block as many custom sites as you need. 100% free. No account, no subscription, no limits. Install LockIn if you want a simple switch that actually stops you from opening time-sink sites, and turns that discipline into visible progress instead of just guilt.
