Here's an open source alternative: https://github.com/SelfControlApp/selfcontrol/

I use Self Control occasionally, but it does sometimes block things that are not on the blacklist†.

I hit this problem once. I was working on integrating some software with a public API when Self Control blocked access to the same API. Fortunately I'd only set the timer for a short while so I just had to wait it out.

The application itself does seem to be open source

Does anyone have UI issues with SelfControl? I run SelfControl on a schedule using AppleScript and cron but often the program will get stuck (clicking SelfControl's UI button will do nothing). If anyone has a better way to automatically block internet access at set times (without using the router), let me know.

+1 for Open source software

+1 for Self Control. Does the same thing, is free.
