Chomper is an internet blocker for helping prevent procrastination/mindless web surfing. It’s in the same vein as Cold Turkey or SelfControl. However, neither of these programs support Linux, and the only similar program hasn’t been developed in over 7 years. So, I developed Chomper.
Chomper has a simple command-line interface through which you can implement blacklists and whitelists at the URL level (e.g. you can block amazon.com/gp/video/*, but not amazon.com). You can see a demo of its use in a gif at the Github repo. I’ve been using it successfully for the last week, and I finished polishing it off so that it’s fit for general use. It’s GPL-licensed. I’ve written a bit more here about my motivation for creating Chomper. Please try it out, and let me know how you like it!
