What is LeechBlock?
LeechBlock is a simple free productivity tool designed to block those time-wasting sites that can suck the life out of your working day. All you need to do is specify which sites to block and when to block them.
You can specify up to six sets of sites to block, with different times and days for each set. You can block sites within fixed time periods (e.g., between 9am and 5pm), after a time limit (e.g., 10 minutes in every hour), or with a combination of time periods and time limit (e.g., 10 minutes in every hour between 9am and 5pm).
With the lockdown feature, you can block sites immediately for a specified duration.
You can also set a password or random access code for the options page, just to slow you down in moments of weakness!
The sites to block can be specified using wildcards (e.g., *.somesite.com) and exceptions (e.g., +allowme.somesite.com).









Comments and Reviews
Its a great software and works as intended. A lot of option to customize the block times and has really helped me to cope up with my studies. Thanks dev
Allows fine-tuned control over what to block when and also to use a custom website or image for the blocking page
Superior (IMO) to BlockSite, which was what I was using previously. More flexible & has lockdown features. Still can't stop me from disabling the app itself, however.
LeechBlock does not run on iPhone:

"LeechBlock is available for Mozilla Firefox, Google Chrome, Microsoft Edge, and other Chromium-based browsers such as Brave, Opera, and Vivaldi," [0]. Sometimes I use a different web browser, such as Safari, for troubleshooting. Or I might use a different web browser to intentionally bypass LeechBlock. I would prefer an app that did not require the discipline not to do this.

Because LeechBlock works as a browser extension, it does not block standalone games and apps.
"You can also set a password or random access code for LeechBlock’s options page, just to slow you down in moments of weakness!" [0] But I wish that LeechBlock supported a delay feature like Plucky [1].

The LeechBlock website says, "LeechBlock is not designed for parental control or for blocking offensive content. You are advised not to try to use it for these purposes." LeechBlock has an advanced option, "Load list of sites from URL," but it does not come with any preset lists of sites to block.
can be a pain in the ass to configure, but works well, just as intended
A lot of depth to this blocker. More customizable then other blockers.
Most customizable free app in town! Used it on FireFox, so happy to find a version for chrome! Couldn't go back to FireFox just for this extension, so thanks to the devs for having a Chrome version.
Beautiful frequently updated extension. Its main pro like I said is that it's highly customizable + free.
