OpenTomato is a Pomodoro timer for Chrome with no ads, no paywall, no accounts, and no trackers. Every setting and every second lives only on your device.
A focused feature set built around one goal: helping you work in short, sustainable bursts — without selling your attention to anyone else.
Set your own focus, short-break, and long-break lengths, plus how many focus sessions happen before a long break.
Get a gentle tone when a session ends, and an optional heads-up warning before time runs out.
Blacklist distracting sites, or lock in with a whitelist of only what you need. Blocking is active during focus time only — breaks are always unrestricted.
No accounts, no servers, no analytics. Your settings, timer state, and focus-time history live in your browser's local storage and never leave your device.
Every feature is free and available from the moment you install it. Nothing to unlock.
The full source is public on GitHub, so you — or anyone — can see exactly what it does.
The classic Pomodoro technique, tuned to your pace.
Click the OpenTomato icon and hit Start. Default is 25 minutes — fully adjustable in settings.
After each focus session, a short break begins automatically — no blocking, no restrictions.
After four focus sessions (or however many you choose), enjoy a longer break before starting over.
A no-install taste of the timer, alert sounds, and notifications, running right in your browser. Tasks, site blocking, Restrictive Mode, and focus stats live in the extension — that's the full version.
Install OpenTomato and start your first Pomodoro in under a minute.
