Just wanted to share a new OSS project I just put out over the weekend; php-api-seed. It's a RESTful API backend written in PHP that powers some of my personal sites, like Analog Studios. It uses Slim as the micro-framework, JWT for authentication, and can be deployed as a phar.
It definitely has some room for some refactoring improvements, and I'm always open to feedback, in particular around security.
