Yes, a Chrome extension can block websites without an account: core blocking runs locally in the browser with no login. MonkeyBlocker works this way, keeping core use local and without server tracking, with daily limits, schedules, a Social Cleaner and an impulse pause — so you protect focus without handing your browsing to a dashboard.
Why some people avoid account-based productivity tools
A lot of focus tools now start the same way: create an account, log in, sync your data to a dashboard. For some people that is fine. For others it is exactly the wrong trade — you wanted to spend less time being tracked online, not hand over a detailed record of every site you struggle with. A required login also adds setup friction to something that should take two minutes.
What no-account website blocking should mean
Done right, a no-account blocker keeps your rules where they belong: in your browser, on your machine. MonkeyBlocker's differentiator is privacy by default — core use stays on the device, with no account required, unlike cloud tools such as Freedom or RescueTime that centre on a synced profile. The pain "I don't want another tracked account" maps to local, no-login operation.
Local rules, privacy and honest limitations
Being local has real benefits and real limits, and it is worth being straight about both. Your blocklists, limits and schedules live in the browser and do not require you to sign in to work. The honest caveat: because there is no account, there is no cloud sync, so your setup does not automatically follow you to another computer, and privacy specifics should always be checked against the extension's own current disclosures rather than assumed.
What MonkeyBlocker does in Chrome
Inside Chrome you still get the full friction stack without an account: Daily time limits with a floating timer, Smart Schedules, a hard blocklist, an Impulse Check before a distracting site opens, a Scroll Stopper for infinite feeds, and a Social Cleaner for Shorts and Reels. Everything you need to protect focus, none of the sign-up.
When an account-based tool is better
If you specifically want synced cloud profiles across several machines, enforced cross-device blocking, or team dashboards, an account-based tool is the right call. No-account use is a feature for privacy and simplicity, not a universal win.

Frequently Asked Questions
Can I use MonkeyBlocker without an account?
Yes. Core blocking, daily limits, schedules and the Impulse Check work locally in Chrome with no account and no login required.
Does MonkeyBlocker track my browsing?
Core use is designed to stay local in the browser rather than being uploaded to a server-side profile. For exact data handling, always check the extension's current privacy disclosures, since specifics can change as features evolve.
Does it sync across my computers?
No. Because there is no account, your setup stays on the machine where you configured it and does not sync to other computers. If you need cross-device sync, an account-based tool fits better.
Is MonkeyBlocker a good fit for me?
Good fit if privacy and zero setup matter and your focus problem is in Chrome; less suited if you specifically want synced cloud profiles across machines or enforced cross-device blocking.
