Dendrite 
Dendrite will be a second-generation Matrix homeserver written in Go.
It's still very much a work in progress, but installation instructions can be found in INSTALL.md. It is not recommended to use Dendrite as a production homeserver at this time.
An overview of the design can be found in DESIGN.md.
