Prevent distractions and maintain focus with a site blocker! Use custom blocklists and password protection to control your internet usage.
If you find yourself getting sucked into the internet abyss, a site blocker could be the perfect solution. Set a time limit for distracting sites, and once you reach that limit, the site blocker will take over and prevent you from wasting any more time.
Designed to enhance productivity and eliminate distractions, a site blocker will remove all time-wasting websites from your life, enabling you to focus on studying, learning, and working.
To use a site blocker, simply set a password, select which websites you want access to, and let the blocker do the rest. If you need to visit a blocked site, enter your password and decide how long you want to stay on the site.
Parents can also use a site blocker by setting a password for their children, or you can have a friend or partner set the password for you to help keep you focused.
With features like the ability to block sites and subdomains, allowlist exceptions, and focus mode, which uses the Pomodoro technique to break down tasks into intervals followed by a short break, a site blocker is the ultimate tool for time management and productivity.
Other features like showing how many work cycles you completed during a session, password protection, unstoppable focus mode, and funny blocked page make this tool even more beneficial for those who want to stay productive and achieve their goals.
Remember, to block sites in incognito mode, you need to activate the "Allow run in incognito mode" checkbox on the chrome://extensions page.
Block Site is one of the best productivity tools available, and it can help you procrastinate less, become more productive, and achieve your life goals. With a site blocker, you'll never have to worry about losing focus again!

- (2025-06-21) Varsha Dalal: Its a really really good site but I hope there is a option to add exception pages which we can excess in focus mode also because I study from my laptop so whenever I am watching video lectures or some important websites I need to stop the focus mode.
- (2025-06-17) Nils64: It does help but I find it to easy to stop sessions
- (2025-06-15) Khang Võ Đức: gut
- (2025-06-09) Aadesh Singhal: good
- (2025-05-25) Akshay Shahi: very good
- (2025-05-16) Sandra Ionescu: I love Site Blocker, and I especially appreciate that it works in Incognito Mode as well, which most other such plugins do not do. This has greatly reduced my procrastination at work (where I tended to access my ”rabbit hole” sites in Incognito Mode just to relax for 5 minutes, but I would end up spending 2 hours instead). Site Blocker makes it easy to block and unblock sites, the interface is simple to figure out (even for someone in a hurry), and I like the flexibility. If one day I legitimately need to go on Reddit or Quora or Wikipedia to check something, I can temporarily unblock the page and re-block it, very easy and hassle-free.
- (2025-05-07) Daniel Keebler: I've never written a review here before about anything - but this extension is a GAME CHANGER! It's not just a "block list" it's a block list PLUS a Pomodoro Technique tool, which is the PERFECT combo really. I do 90 minute work sessions, then break for 10 (or sometimes 15) minutes, then it automatically starts the 90 mins again and locks down any distracting sites on my block list which is perfect.

- (2025-02-24) Adam M: Works okay, sometimes a blocked site seems to get through. also keeps pestering me to leave a review.
- (2025-02-24) Kevin Jerram: I like the general simplicity of it, but Focus Mode doesn't seem to work. Tried it to work on a report in Google Docs, but this extension still blocks ALL sites after 'allowing' the Google Docs and Google Drive sites I need to use in the settings. I don't see anywhere else to allow these sites or any other settings that make sense to change. Why have an 'allowed' list under Focus Mode settings if those sites are still blocked? Is Focus Mode meant for focusing on work outside of a browser / off a computer? Seems to defeat the purpose if I can't allow certain sites for work.
