Lockby

Stop opening 30 tabs and getting nothing done. Lockby locks your browser to your chosen domains during focus sessions

You sit down to do one thing. Ten minutes later you have 30 tabs open across 12 different sites and zero memory of what you were doing. Lockby fixes that. It restricts your browser to only the domains you choose during timed focus sessions. Need Stack Overflow and GitHub? Whitelist both. Everything else is blocked before it even loads. No willpower required. ➤ HOW IT WORKS 1. Add the domains you need for your task 2. Set a timer (5 minutes to 8 hours) 3. Hit start — your browser goes into lockdown That's it. Any site outside your whitelisted domains gets blocked instantly. ➤ WHAT GETS BLOCKED • Tabs to non-whitelisted domains — closed instantly • Navigation to other sites — redirected back • New browser windows — blocked • Chrome internal pages — blocked (no sneaking through chrome:// as a loophole) ➤ WHAT STAYS OPEN • Any tab on your whitelisted domains — open as many as you need • Navigation within those domains — completely unrestricted ➤ FEATURES • Domain Lockdown — your browser only allows the sites you picked • Focus Timer — countdown in your toolbar so you always know how long is left • Distraction Counter — see exactly how many times your brain tried to wander • Smart Whitelist — allow up to 3 domains for the same task (Pro) • Activity Heatmap — a GitHub-style grid of your focus sessions (Pro) • Session History — every session logged with stats and patterns (Pro) ➤ QUITTING IS HARD ON PURPOSE Need to end a session early? You have to type a full sentence confirming you want to quit, then wait 5 seconds. It is a speed bump between impulse and action. FREE VS PRO Free: 3 sessions/day, 1 domain, up to 45 minutes. No account required. Pro ($3.99/mo): Unlimited sessions, up to 3 domains, unlimited duration, heatmap, history. The free tier is not bait. It blocks distractions for real. ➤ BUILT FOR • ADHD brains that open "just one more tab" every five minutes • Developers, writers, and designers who need deep focus • Remote workers who lose hours to browser rabbit holes • Anyone tired of fighting their own browser ➤ NOT A SITE BLOCKER Traditional blockers make you maintain a list of "bad" sites. That list never ends. Lockby flips the model — you pick the domains you need, and everything else disappears. No blocklist to manage. ➤ PRIVACY Lockby does not collect, store, or transmit your browsing data. Session data stays in your browser. Period. https://www.lockby.app/privacy
