Lock your browser to
only the sites you need.
Pick the domains you need for your task, set a timer, and everything else disappears. No blocklist to maintain. Just a whitelist of what matters right now.
Ready to focus?
Your brain opens 30 tabs.
You get nothing done.
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.
Sound familiar?
Three steps. That's it.
From distracted to done
Add your domains
Pick the sites you need for your task. Your email and a spreadsheet? Add both. Everything else disappears.
Set a timer
Choose 5 minutes or 8 hours. Hit start and your browser locks down. A toolbar countdown shows how long you have left.
Everything else is blocked
Try to open Reddit. Go ahead. Lockby kills the tab before the page even loads. No willpower required.
What you get
Not a site blocker. A focus lock.
Traditional blockers make you maintain a list of bad sites. That list never ends. Lockby flips the model — you pick what you need, and everything else disappears.
Domain Lockdown
Open Reddit out of habit? The tab closes before the page loads. Navigate to YouTube? Redirected back. Your browser only goes where you told it to.
Focus Timer
Commit to 25 minutes or a full workday. A countdown in your toolbar keeps you honest. When time is up, your browser unlocks itself.
Smart Whitelist
Most tasks need more than one site. Allow up to 3 domains on Pro so your email, doc editor, and project tracker all stay open. Everything else stays gone.
Distraction Counter
See exactly how many times your brain tried to wander. Spoiler: it is more than you think. That number alone changes behavior.
Activity Heatmap
A GitHub-style heatmap of your focus sessions. Watch the empty squares fill in and build a streak you don't want to break.
Session History
Every session logged: duration, blocked attempts, and whether you finished. Find out which days and times you actually focus best.
Simple pricing
