Focuser vs BlockSite: a fair comparison

Choose BlockSite if you want to block sites on your phone and your computer, want a password lock, or want extras like categories, keyword blocking and a Pomodoro timer.

Choose Focuser if you work in desktop Chrome, want to keep access to sites you sometimes need, and do not want an account or a subscription. Focuser does not lock you out. It asks why you are there and how long you need.

Both tools can pause or block sites on a schedule, so work hours are covered either way. The real question is whether you want a wall or a question.

The table uses each product's own pages and its Chrome Web Store listing. Prices and ratings change, so check the sources below before you decide.

Read the ratings with care. Focuser's 5.0 comes from only a few ratings. BlockSite's 4.5 comes from many thousands, so it says more about how people find it.

BlockSite runs on far more devices. It has apps for Android and iOS, a desktop app, and extensions for Chrome, Edge and Firefox. If you want the same blocks on your phone and your laptop, Focuser cannot do that.

It also has more tools. You get categories, keyword blocking, a Pomodoro focus mode, usage limits, insights, an adult content filter, a custom block page and redirects. If you want your settings protected by a password, BlockSite has that and Focuser does not.

Sync across devices needs a BlockSite account, and with one your list follows you from device to device. BlockSite also has a much larger user base, so there are far more reviews to read before you decide.

Everything in Focuser is free. There is no plan to upgrade to and no account to create. BlockSite has a limited free plan, and common complaints in its reviews are the free plan limits, upgrade prompts and the subscription price.

Setup is short. You add the current tab from the popup with one click or type any domain, and a domain covers its subdomains. There is nothing to sign in to.

The approach is also different. Some BlockSite reviews say the block is easy to get around in Incognito or in another browser. Focuser has the same limits, since it only runs in Chrome and needs your permission to work in Incognito. It simply does not rely on a wall. It asks a question, takes a reason and a time limit, and shows a timer. When the time is up, it asks again.

This is the clearest difference between the two. BlockSite's privacy policy, last changed on July 16, 2026, says it collects browsing, search and activity data and may share it with affiliates for market intelligence. It says this may count as a sale of data under some US state laws. You can opt out in its settings.

Focuser makes no network requests at all. Your sites, schedules and reasons are saved in Chrome storage and sync only through your own Chrome profile. Your stats stay on your device, and nothing is sent to us.

If privacy matters most to you, read BlockSite's policy in full before you decide.
