APIQ is a modern and flexible Ruby on Rails content management system with modular approach. It utilizes the most latest features from Rails and PostgreSQL (such as json column type, for example). Mostly inspired by LocomotiveCMS, but in contrast with it APIQ relies on robust PostgreSQL database and doesn’t provide all-in-one solution. The basic idea behind APIQ: minimal core, extendable via extensions (engines). So you can take only what you need.
The most powerful feature behind APIQ is templating engine called Liquor. If you’re familiar with Shopify’s Liquid templating engine, then you already know Liquor. In Liquor it’s a little bit easier to extend its core as well as it has really simple Rails integration.
