Reflex is the name of a website engine I built for my website a long time ago with the intent of commercializing it. It is written in PHP with the intent of being modular, so you could add plugins to do pretty much anything.
I never actually finished the project (because some things I wanted were too much demanding for PHP). This website has run for some time on an early prototype of Reflex, but has now transitioned to PieCrust.
I might restart the effort someday, and there’s a strong possibility that I will be switching to another programming language.
