Liquid is a templating engine for creating web pages. From the Liquid website:
Liquid is an extraction from the e-commerce system Shopify. Shopify powers many thousands of e-commerce stores which all call for unique designs. For this we developed Liquid which allows our customers complete design freedom while maintaining the integrity of our servers.
Liquid has been in production use since June 2006 and is now used by many other hosted web applications.
It was developed for usage in Ruby on Rails web applications and integrates seamlessly as a plugin but it also works excellently as a stand alone library.
Liquid has been in production use at Shopify since 2006, and is also used as the main templating engine on GitHub pages through the Jekyll static site generator.
