Video Demo
From an hour lost to a feed to one click and back to work.
Block it, and stay blocked
Simple enough to set up in seconds, strict enough to actually work.
Block this site
Click the FocusGeek button on any site and choose Block. Every subdomain is blocked too.
Quick add groups
Block social media, news, video or shopping in one tap. The lists are yours to edit.
Focus timer
Start a 25, 50 or 90 minute session, or your own length. The time left shows on the toolbar.
Schedules
Block on set days and times, like weekdays 9 to 5. Overnight times work too.
A calm blocked page
Blocked sites show a quiet page with the time left and a Back to work button, not an error.
Short breaks
Need a site for real? Allow it for 5 minutes after a 10 second pause and typing its name.
Strict mode
During a focus session, no breaks, no ending early and no removing sites until the time is up.
Allow list mode
Flip it round: block everything except the sites you need for work.
Your browsing stays private
The browser does the blocking from FocusGeek’s rules, so FocusGeek never reads or sends your browsing.
How to install it
About a minute, and you only do it once. Store listings for Edge and Firefox are on the way.
Download and unzip
Download the ZIP and unzip it somewhere you will keep it, such as Documents. The browser runs the extension from that folder, so leave it there.
Open your extensions page
Type chrome://extensions in the address bar. In Edge use edge://extensions, in Brave brave://extensions.
Switch on Developer mode
The switch is top right in Chrome and Brave, and bottom left in Edge. It just lets you add an extension from a folder.
Load unpacked
Click Load unpacked and pick the focusgeek folder. Then pin the FocusGeek icon from the puzzle piece menu.
On Firefox, download the Firefox version, open about:debugging, choose This Firefox, then Load Temporary Add-on and pick the ZIP. Firefox removes temporary add-ons when it closes, so the Firefox Add-ons listing will be the easier option once it is approved.
See it in action
Every step, exactly as it looks in your browser.
Who it is for
Anyone who has opened a site for one quick look and lost an hour.
Working from home
Keep social media and news away during work hours with a schedule.
Students
Block the distractions for a study session with the focus timer.
Anyone building better habits
Make the sites that pull you in a little harder to reach, with breaks when you really need them.

Frequently Asked Questions
Is FocusGeek really free?
Yes. There is no Pro version, no ads and no limit on how many sites you block. It is open source under the GPL-3.0, so you can read every line of it on GitHub.
Does FocusGeek see the sites I visit?
No. The browser does the blocking itself from the short list of rules FocusGeek gives it, so FocusGeek never reads your browsing. It makes no network requests at all, and nothing is sent anywhere.
Why does it ask for access to a site when I block it?
Browsers only let an extension show its own page on a site it has access to. If you say no, the site is still blocked, but you see the browser’s plain error page instead of FocusGeek’s calm one.
Can I still get to a blocked site if I really need it?
Yes, unless strict mode is on during a focus session. On the blocked page, choose Allow for 5 minutes, wait 10 seconds and type the site’s name. You can change the break length or switch breaks off.
Can I block sites only during work hours?
Yes. Pick On a schedule in Settings, choose the days and the times, and FocusGeek switches blocking on and off by itself.
Can I block single pages instead of a whole site?
Not yet. FocusGeek blocks whole sites, including every subdomain under them.
Does it work in private windows?
Only if you allow the extension in private or incognito windows in your browser’s extension settings. Then it blocks there too.
Does it work on Firefox?
Yes. Download the Firefox version from this page. A Firefox Add-ons listing is in review and will make installing it permanent.
