tunl — Block distracting sites while you focus

Focus timer that blocks distracting sites

tunl blocks distracting sites while you focus. Set a timer, hit start, and your blocklist kicks in. Try to open Twitter, Reddit, or YouTube mid-session — you'll get redirected to a quiet page with a countdown instead. No way around it until the timer runs out. Quitting early isn't easy either. There's a cooldown before you can end a session, and you have to type "end" to confirm. It's friction by design — so the impulse passes before you give in. For people with a routine, schedules let you automate blocking entirely. Set "Work Hours" to 9–5 on weekdays, and tunl activates on its own. No button to press, no willpower needed. You can track your progress too. See how many minutes you've focused today, this week, or this month. Build a streak and watch it grow — or break it and start over.
