Sleepy is a hybrid PHP/Go web framework and Cecil is a flexible CMS built around Sleepy. Together, they attempt to make building dynamic websites less tedious and time-consuming.
A more in-depth introduction to Sleepy and Cecil can be found in the original blog post here. An overview of Sleepy’s architecture and design considerations will follow, along with a small tutorial on making a simple website.
