# Awesome Matrix [![Awesome](https://awesome.re/badge.svg)](https://awesome.re)



A curated list of things related to the [Matrix](https://matrix.org/) ecosystem,

including software, research, etc. Matrix is an open protocol for secure,

decentralized data stores with a focus on communication.



This list hopes to become a good place for finding projects that may not have an

obvious category to fit into on the matrix.org website.
