Unicorn is a utility for Sitecore that solves the issue of moving templates, renderings, and other database items between Sitecore instances. This becomes problematic when developers have their own local instances - packages are error-prone and tend to be forgotten on the way to production.
Unicorn solves this issue by using the Serialization APIs to keep copies of Sitecore items on disk along with the code - this way, a copy of the necessary database items for a given codebase accompanies it in source control.
