Many people, including me, love the Dia browser for its clean interface and productivity features. However, online distractions can still get in the way when you’re working. Once you visit an interesting website, it’s easy to get caught up and spend more time scrolling than you planned. To find a better way to stay focused, I tested several website blockers for Dia. In this article, I’ll share my experience and show you how to block websites on Dia effectively.

My testing environment: Dia browser on macOS Tahoe 26. Websites tested: YouTube, Reddit, and other common distracting websites. Testing criteria: Ease of setup, compatibility with Dia, website blocking performance, bypass protection, and scheduling features.

 

1. Use Cisdem AppCrypt to block websites on Dia (Recommended)

Best for: Blocking specific websites or website categories on Dia and other browsers on Mac.

The Dia browser launched last year. Many website blockers still don't support it. Cisdem AppCrypt added support for Dia in its latest version 7.10.0, making it one of the few website blockers that works with Dia.

Why I chose it

After testing it with Dia, I found AppCrypt useful because

  • It works with Dia, Chrome, Safari, and other browsers on Mac.
  • It lets me block websites with a password, making it harder to bypass.
  • It supports blocking individual URLs or categories of sites.
  • It offers two blocking modes: block list and allow list.
  • It lets me create schedules, which is useful for focused work sessions.
  • The setup process is simple and beginner-friendly.

How I blocked websites on Dia

1. Download and install AppCrypt on Mac.

Free Download macOS 10.15 or later

2. Open it. Set a password.

3. Right-click on its icon on the menu bar. Select Open Main Window.

6. Add websites you want to restrict.

Open Dia and try accessing the blocked sites.

My test result

  • The websites were blocked immediately when I tried opening them in Dia.
  • The blocking also worked in Chrome, Safari, and other browsers on my Mac.
  • The blocking cannot be bypassed without entering the correct password.
  • I could still access work-related websites.
  • The Schedule feature helped me stay focused during work hours.

Overall, AppCrypt worked well for my needs. It is a good choice for users who want stronger control over distracting websites on Dia.

 

2. Use BlockGuard to block websites on Dia

Best for: Blocking short-form content, adult websites, and other distractions on Dia.

I recently tested this website-blocking extension on the Dia browser to see whether it could help reduce my endless scrolling habit.

Why I chose it

I chose BlockGuard because it focuses on controlling the types of content that usually distract me:

It blocks Shorts and Reels on social media sites with one click.

It offers both Blocklist and Whitelist modes.

It can filter explicit content from search results.

It allows me to set daily time limits for specific websites.

It tracks my browsing time on distracting websites.

How I blocked websites on Dia

1. Open the Chrome Web Store in Dia.

2. Search for BlockGuard. Add it to Dia.

3. Open the extension settings. Click Features.

click Features

4. Enable Block Shorts / Reels.

By default, the Adult Website Blocking and Safe Search Enforcement features are also enabled.

5. Go to Blocklist. Enter a website URL such as twitter.com. Click Add Website.

blocklist

My test result

  • The websites I added to Blocklist were successfully blocked in Dia.
  • The blocking only worked in Dia because the extension was installed only on this browser.
  • The Block Shorts / Reels feature also blocked access to the entire YouTube website in my test, as well as Facebook Reels and Instagram Reels.
  • I could still disable or uninstall the extension without entering a password. The blocking could be easily removed.

Overall, BlockGuard is better suited for self-control rather than parental control. Its biggest advantage is the ability to block Shorts and Reels, which helps reduce time spent on social media sites.

 

3. Use StayFocusd to block websites on Dia

Best for: Setting time limits for distracting websites on Dia and reducing unnecessary screen time.

StayFocusd is a browser extension designed for productivity. It’s available for Dia. It helps control browsing habits without completely blocking websites.

Why I chose it

After testing several website-blocking extensions for Dia, I found StayFocusd useful because it focuses on time management rather than only blocking access:

  • It helps me set time limits on specific websites or a group of websites on Dia.
  • It lets me create different blocking groups for different situations, such as work time or break time.
  • It also offers the Allowed Sites mode.
  • The Require Challenge feature makes changing settings less convenient when I want to bypass my own restrictions.
  • It can track screen time across devices by connecting with the StayFree mobile app.

How I blocked websites on Dia

1. Open Dia. Go to the Chrome Web Store.

2. Search for StayFocusd and add it to Dia.

3. Open StayFocusd settings. Click Blocked Sites.

4. Click Add group.

5. Enter the group name. set the maximum time allowed per day. If you want to block a site completely, set the time limit to 0 hours and 0 minutes.

6. In the “Enter blocked websites” box, enter the websites you want to block on Dia.

save group

7. Click Save Group.

My test result

  • Websites were blocked automatically after I reached the daily time limit.
  • Setting the allowed time to 0 minutes per day completely blocked access to the selected websites.
  • The Require Challenge feature added an extra step before changing settings, which helped reduce impulsive changes.
  • However, I could still remove the restriction by disabling or uninstalling the extension from Dia.

Overall, StayFocusd works best for users who want to control how much time they spend on distracting websites instead of completely blocking them.
