OpenIM isn't just an open-source instant messaging component, it's an integral part of your application ecosystem. Check out this diagram to understand how AppServer, AppClient, OpenIMServer, and OpenIMSDK interact.
**OpenIMSDK** seamlessly integrates into your application, delivering a rich, real-time messaging experience without requiring intricate UI integration. It provides:
+ **Modular Composition**: It's comprised of several modules, such as the gateway and multiple RPC services, offering a versatile messaging environment.
+ **Microservices Architecture**: Supporting cluster modes, it assures outstanding performance and scalability to manage communication effectively across various instances.
+ **Diverse Deployment Options**: Adapts to your operational preferences, offering deployment via source code, Kubernetes, or Docker.
+ **REST API**: OpenIMServer provides REST API for business systems, aiming to empower your operations with additional functionalities like group creation and message push via backend interfaces.

🤲 In order to facilitate the user experience, we have provided a variety of deployment solutions, you can choose your own deployment method according to the list below:
We have our own version management policy, if you are interested in our version management, I recommend reading [📚 OpenIM Version](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/version.md), We recommend using stable versions such as `v3.3.0` and `v3.2.0` whenever possible. `v3.1.1-alpha.3` as well as `v3.3.0-beta.0` and `v3.2.0-rc.0` are pre-release or beta versions and are not recommended.
Set `OPENIM_VERSION` environment variables for the latest `OPENIM_VERSION` number, or replace the `OPENIM_VERSION` for you to install the OpenIM-Server `OPENIM_VERSION`:
