Instant messaging server and infrastructure for chat applications.
OpenIM provides messaging servers and client SDKs for developers adding communication to their own applications, rather than a finished standalone chat app. Its components cover messages, users, groups, friends and conversation sessions. Backend services can create groups or push messages through REST APIs and receive event webhooks. The server supports source, Docker and Kubernetes deployment.
