TIMEBOX

Stop losing your afternoon to "just checking" those distracting sites.
Focus, on your terms.
Timebox is a focus tool that blocks distracting websites the way YOU work - not with a rigid, one-size-fits-all list you can't touch. Pick how a session starts, decide exactly what's off-limits, save your favorite setups, and even schedule it all to run itself. No accounts, no cloud, no tracking - everything stays on your own device.

HOW YOU FOCUS IS UP TO YOU
  • Manual mode: block everything until you personally turn it back off.
  • Timed sessions: pick 25, 45, 60, or 90 minutes and it stops on its own.
  • Pomodoro mode: 25 minutes locked in, 5 minutes free, repeating for as long as you like.
    Three ways to start a session, zero ways to accidentally leave it blocking forever.

BLOCK WHAT ACTUALLY DISTRACTS YOU
Organize sites into groups - Social Media, News, Shopping, and Adult content come built in - and flip an entire category on or off with one switch. Add your own sites to any group, or leave them ungrouped with their own individual toggle. It's your list, arranged your way, not a fixed blocklist someone else decided on.

ONE CLICK, HOWEVER YOU LEFT IT
Set up your ideal "Work" configuration once - which groups are on, which are off - and save it as a Profile. Switching between deep-focus mode and a lighter setup is one click, not five minutes of re-toggling.

SET IT AND FORGET IT
Schedule sessions to start automatically on the days and times you already know you need to focus - no need to remember to hit start every single morning.

PEACE OF MIND FOR SHARED DEVICES
Need to keep a shared computer - or a child's browsing - off-limits during certain hours? Set a password and lock the browser completely. Every open tab is safely tucked away and reopens automatically the moment it's unlocked, and a built-in auto-unlock timer means nobody can ever get permanently locked out. Lock it manually whenever you need to, or schedule it to lock itself, every day, on its own.

BUILT FOR PRIVACY
Timebox doesn't ask for an account, doesn't phone home, and doesn't track what you do. Every setting, every blocked site, every schedule lives in your browser's own local storage - full stop.


Timebox is aimed for anyone who is looking for a simple and easy to use tool for improving their focus. This includes:
  • Students who need a distraction-free study session
  • Remote workers protecting their deep-work time
  • Anyone who's opened one "quick" tab and lost the whole afternoon
  • Parents managing screen time on a shared or child's browser
    Take back your attention. Install Timebox and decide, for once, what your browser is actually allowed to show you.
