One tab. One task.
Zero distractions.
A Chrome extension that stands between you and your 47th open tab. Built for ADHD brains and anyone who opens “just one more tab” every five minutes.
Ready to focus?
Your brain opens 30 tabs.
You get nothing done.
You sit down to finish one thing. Ten minutes later, you're deep in a Wikipedia spiral with 30 tabs open and zero memory of what you were doing.
Sound familiar?
Three steps. That's it.
From distracted to done
Pick your site
Paste the URL you need to work on. That's the only site your browser will open.
Set the clock
Choose 5 minutes or 5 hours. Hit start and your browser goes into lockdown.
Finish what you started
Try to open Reddit. Go ahead. Lockby blocks it before the page even loads.
What you get
Your browser, but with guardrails
No complicated setup. No willpower required. Just a few tools that make distraction physically impossible.
Tab Lockdown
Open a new tab? Closed. Navigate somewhere off-limits? Redirected. Your browser becomes a one-track machine.
Focus Timer
Set 25 minutes or 4 hours. A countdown badge in your toolbar reminds you how long you have left.
Smart Whitelist
Need Google Docs and Notion for the same task? Allow up to 3 domains on Pro. Everything else is blocked.
Block Counter
See exactly how many times your brain tried to wander. Spoiler: it's more than you think.
Activity Heatmap
A GitHub-style grid of your focus sessions. Watch your consistency build day by day.
Session History
Every session logged: how long you focused, what got blocked, and whether you finished. Spot patterns over time.
What it costs
Free is not a trick. Pro is not a requirement.
The free tier blocks distractions for real. No credit card, no trial countdown. Pro adds analytics and removes limits.
