Description from store
If you want some time to browse online but hope to avoid a full-blown internet spiral, a site blocker might be perfect for you.
Set a time limit for distracting sites. When you reach the limit, a block goes into place. That means you still get to check your feed now and then, just not for too long or too often.
Site blocker is designed to help you stay focused on studying, learning, and working. Blocks all time-westing websites to keep you productive and away from all the distractions the internet offers.
To use a site blocker, set a password, decide which websites you want access to, and let the site blocker block the rest. If you want to visit a site you have blocked, enter your password, and decide how long you want to be on the blocked site.
If you’re a parent, you can set the password for your child. Or, if you’d like to use it yourself, have a friend or partner put it for you to help you concentrate.
And voila! You now have a set of internet guardrails that help to help you stay productive and on task whether you’re studying, remote learning, or need an extra boost of self-control to finish a project.
⭐️Features⭐️
👉 Block sites, including its subdomains
Remove all distracting and harmful websites from your life by blocking them for you while you need to stay focused and productive.
👉 Allowlist
Add exceptions to the blocked websites list. Sites from this list avoid all blocking settings.
👉 Focus mode
The focus mode timer lets you control your schedule via the Pomodoro technique. Break down your tasks into intervals followed by a short break. With ‘Focus Mode,’ you can set times to disable websites and browse freely.
👉 Time management
Show how many work cycles you completed during a session. So you’ll be able to get all your tasks done and still have time to browse your favourite sites and apps in between.
👉 Password protection
If you start focus mode, you can stop it with a passcode of your choosing, making it harder to procrastinate. You can also password-protect the options page to keep you from efficiently removing sites from your list.
👉 Unstoppable focus mode
Select the option to hide the pause and stop buttons in the extension settings. And you won't be able to stop blocking sites until the block time expires.
👉 Funny blocked page
You will now see funny images if you are trying to enter a blocked site. To do this, you need to enable this option in the site blocking settings. You will still not be able to enter the blocked site, but perhaps a funny picture will make you smile :))
Block Site is one of the best productivity tools available to help people procrastinate less, become more productive and reach their life goals. You’ll never have to worry again about how to stay focused at work.
⭐️Note⭐️
To block sites in incognito mode, you need to activate Allow run in incognito mode checkbox on the chrome://extensions page.

- (2025-07-29) Sima /Angelin Singha: Works pretty well. With the help of this extension I can now finally avoid getting distracted. I recommend using FocusGuard for first 2 weeks or so while you work and then you will eventually see that you are not needing the help of extension to avoid distractions--focus will come to you naturally..........

- (2025-07-24) Mike De Guzman: It does what it's supposed to do with no bloat. I can block websites, I can set up a password so that I can't unblock them easily. There's also a Focus mode where I can set up intervals of focus time and break time.
- (2025-07-24) Ajit Velumani: its one of the good extension among the alternatives. Have been using for two weeks to block some entertainment websites like youtube and it works great. Does what it is intended to do. Kudos to the team for developing it.. One thing I would suggest is, once the website is unblocked, the older link does not seem to work. this is especially if tab opened is a youtube video. if blocked and unblocked for viewing purpose, the link is broken. I need to check it again and make sure this occurs always.

- (2025-07-03) Paul Pavlidis: Does what I want. Spams to rate itself, I gave up and here I am but you lost a star for annoying me. I would have been happy to tip you a few bucks instead. One more star lost for making me click twice to turn focus mode on.

- (2025-06-30) LP A: App is broken. Can't add sites to the list because it says the site is already added even though it's not. On top of that, it spams for a rating; so here's the rating.
