Holdfast: Pomodoro Timer & Website Blocker

Pomodoro focus timer and website blocker in one — block distracting sites while you work. No account, no server, works offline.

Holdfast is a focus timer and website blocker that actually holds the line. Start a Pomodoro or a stopwatch, and the sites that pull you away stop loading until your break. No sign-up, no dashboard, no subscription to read your own data. Everything runs on your machine. WHAT IT DOES • Pomodoro with configurable focus, break, long-break and set count • Stopwatch mode when you don't want a countdown • Blocks your chosen sites only while a session is running • A calm block page that shows how long is left, instead of a browser error • Remaining minutes on the toolbar icon, so you can close the popup • Today / this-week focus totals PRO ($2.99/month) • Unlimited blocked sites (5 on the free plan) • Category presets — social, entertainment, news, shopping, games • Schedule — block automatically during set hours, session or not • Strict mode — you cannot end a session or edit the list mid-focus • History — daily focus time and session count • One licence covers 3 devices PRIVACY Holdfast has no server. Your blocklist and settings live in Chrome's own sync storage; your focus stats never leave your machine. We do not collect, transmit or sell anything. The only network request the extension ever makes is to verify a Pro licence key, and only if you bought one. The extension asks for site access only when you add a site to your blocklist, so it can show its own block page there instead of a browser error. Decline and blocking still works — you just get Chrome's default blocked screen.
