I'm pretty involved in the open source software world in this space. I'd recommend you'd look into these two projects below. Neither of them are a "filter". In my experience though, filters are marginally useful anyways. https://netresponsibility.com https://netresponsibility.com -- is accountability software. It monitors the sites you visit and sends reports to a friend of sites it thinks are "bad". This, in my opinion, is far better than filtering software because it forces you to have a conversation with your partner about what went down and why. It has gotten pretty stale and the current released version is basically non-working because dependency updates have broken a lot of things. A few devs are working on the next version (v4) on and off trying to get it off the ground. It works well, just needs more testing and more contributors. This runs on *nix and osx. https://fasterscaleapp.com https://fasterscaleapp.com -- is a tool to help you become more self-aware of your emotional status and why you feel whatever way you feel. Addicts are notoriously awful at identifying what they're really feeling (and people in general are worse than they might initially think). The idea is that as you become better able to identify the direction you're headed in you can take actions to prevent a relapse or acting out BEFORE you get to that point. Both of those projects are OSS and the repos should be easily findable from those websites. Both of these projects would really benefit from help, contributors, and just regular users. Net Responsibility has a forum and mailing list that you can get involved in. Faster Scale App is not quite as organized, it's just one guy working on it.
