Open-source Team Messaging Platform
"Raven is a simple work messaging tool that is built using the Frappe framework and can be installed on any new or existing Frappe site (e.g. in addition to ERPNext or Gameplan).
It is designed to help teams collaborate and communicate with each other and get work done. Teams can create their own channels (publically viewable or private) and send messages, emojis, files and images.
The frontend is built using React & ChakraUI."
