OpenIM

Open source instant messaging service for developers with web, admin, and self-hosted server components.

Description

OpenIM is an open source instant messaging server stack for developers, including a web client, an admin console, and self-hosted backend services. The Lazycat package persists MongoDB, Redis, etcd, Kafka, MinIO, and application data, and provides passwordless login for the built-in admin account. Phone or email verification-code login uses OpenIM Chat's built-in super code 666666 by default, without external SMS or SMTP delivery. Real SMS or email delivery requires rebuilding with Aliyun SMS or SMTP settings in the deployment configuration.
