At its core, antifa-cms is a flat file content management system. It's based on the popular Pico CMS written in PHP.
I made antifa-cms because building and hosting your own custom built webserver isn't easy for non-technical people. Hiring someone to build a webpage is very expensive. That leaves a lot of voices silenced. What also silences people is when corporations make changes that disrupt our capacity to communicate and publish our ideas. Yes, I'm talking about Twitter.
With antifa-cms, you own and controll everything. You can publish what you want to publish without fear or favor. Obviously local laws against libel, hate speech and directed violent rhetoric should be taken into consideration when publishing. If you screw up and someone comes after you for libel or copyright infringement, I don't know you because I don't know you.
Building and publishing antifa-cms actually costs me money. I charge no one any money and I run no ads. My revenue stream is precisely zero. I'm doing this completely free of charge because I think this information can be helpful to people.
Any organization or small business can benefit from using antifa-cms. You don't have to be an anti-fascist, to use antifa-cms, but it's implied by the name.
