BlockSite Review 2026: Is It a Good Tool to Block Websites?

Download and installation

You can download and install the BlockSite extension in the extension store of your browser. You can download and install the BlockSite app from the Play Store app on an Android phone or the App Store app on an iPhone. The installation of an extension or app is very easy, just as you install other extensions or apps.

Features and performances

This part of the review focuses on the BlockSite extension and also talks about the BlockSite app.

• Block user-specified websites BlockSite allows you to add specific websites (like youtube.com) or pages to the block list.

• Block user-specified keywords Once you add a certain word (like game) to the block list, all URLs containing the word will be blocked.
• Block certain websites categories It offers 6 websites categories for you to block in bulk, including Adult, Social, News, Sports, Shopping, and Gambling. Once a category is added to the block list, websites in that category will be automatically detected and blocked.

• Import and export the block list You can export your current block list to a CSV file. You can also import a list that you exported or create a CSV file with a list of unwanted websites. But you may have a problem importing a file created by you. Note that the import/export feature supports websites and pages but not keywords.
• Block all websites except ones on the whitelist There is a whitelist mode. To make your browser completely distraction-free or child-safe, you can use this mode. However, there isn’t a separate whitelist. Turning on the whitelist mode turns the blocklist into a whitelist. This means that you have to empty your blocklist first and then add the allowed websites to this list, which can be very inconvenient.
• Use the schedule feature There’s a schedule feature, allowing you to turn on the blocking of items on the blocklist only during certain times like work hours and turn off the blocking in your leisure time.

• Use the Focus Mode feature There’s another way to turn on or off the blocking. You can use the Focus Mode, which is basically a pomodoro timer. When this mode is on, the blocking is automatically turned on during the focus time and off during the break time.

• Protect your block list with a password There’s a password protection feature. If you set a password, you or someone else has to enter the password to open BlockSite’s option page (where one can edit the block list, change the schedule and do more). However, the password can’t prevent one from uninstalling BlockSite at all. Once BlockSite is uninstalled, all unblocked websites will be unblocked and accessible.
• Block individual apps In addition to restricting access to websites, the BlockSite app allows you to block access to specific apps on your Android phone or iPhone. The Focus Mode and schedule feature are available for app blocking as well.

Summary

When BlockSite is installed on a browser, you can use it to control access to certain websites on this browser. But the blocking is at the browser level. It can’t block websites on the browser on which it isn’t installed or that it doesn’t support (like Safari or Opera). BlockSite offers a rich list of features and options to improve efficiency and personalize the blocking. But it’d be better if there were a separate whitelist.

There’s a layer of protection to prevent one (like your child) from unblocking websites by editing the block list or by turning off BlockSite. However, this is far from enough. Whether you are using BlockSite for yourself or your kids, it’s easy for anyone with access to the browser to uninstall BlockSite.

All in all, BlockSite provides useful features, good ease of use and good customizability but not enough effectiveness.

Tutorial

Below you will find the steps on how to use BlockSite and tips that may help if BlockSite doesn’t work.

How to use BlockSite

The following steps use the Chrome browser as an example.

1. Go to the Chrome Web Store.

2. Use the search field to search for BlockSite by blocksite.co.

3. Click the Add to Chrome button. Click Add extension in the message that appears.

4. You will be presented with the Options page of BlockSite. Optionally, click the Extensions icon in the toolbar of your Chrome and pin BlockSite to make it appear in the toolbar.

5. In the left sidebar, click the Block Sites tab. Click the Add to Block List button. Do any or all of the following things:

• Click the Websites tab. Enter the website that you want to restrict in the field above. Click the Add icon next to this website. Add other unwanted sites.
• Click the Keywords tab. Enter the keywords that you want to block in the field above. Click the Add icon next to this keyword. Add other unwanted keywords.
• Click the Categories tab. Click the Add icon next to the category that you want to limit access to.

6. Click Done.

7. Right-click the BlockSite icon in the toolbar. Choose Manage Extension. Scroll down and turn on Allow in Incognito.

The last step is optional but recommended. If you don’t do this step, the blocking will only apply to normal browsing, and one can still visit any website in incognito browsing.

As for other features and customization, the BlockSite review above can provide the details.

BlockSite not working? These 4 tips may help

• If BlockSite is installed on your browser but fails to block the websites on your block list, first check your browser settings to make sure you’re signed in with the same account you used to log in to BlockSite. BlockSite works at the account level. If you switch to a different browser account, the blocked websites will still be accessible.
• If BlockSite blocks the websites that are not on the block list, go to BlockSite’s Options pageand check whether you’ve selected a category of sites to block, which may include websites that you don’t want to block.
• If the BlockSite app isn’t working on your phone, go to your phone’s settings to check whether BlockSite has been denied the permissions it needs to run properly. This can happen. If so, grant the required permissions.
• If BlockSite doesn’t work the way that you expect from a website blocking tool, you can try BlockSite alternatives. For example, Cisdem AppCrypt, which offers advanced features and more reasonable pricing.

This tool is easy to use while offering more advanced features to prevent blocks from being bypassed. It supports website blocking on Chrome, Edge, Safari, Opera and Brave. In addition, it allows you to lock any application with a password. So you can lock web browsers too.

There are several ways to temporarily or permanently unblock a website, such as disabling web blocking, quitting AppCrypt, or removing the site from the block list. But all of these actions require the password.

Conclusion

BlockSite is a big name in the world of website blocking tools. BlockSite stands out for being easy to access, easy to use and allowing enough customization and flexibility. It can be a good tool to reduce online distractions. It can also help prevent access to certain inappropriate or harmful web content.

If you are looking for an easy-to-use website blocking tool, it can be a good choice. If you need to make the blocking hard to get passed, you might want to try a more effective tool.
