## Language-agnostic client libraries

Pulsar supports the following language-agnostic client libraries:

| Interface | Documentation                             | Release note                                      | Code repo                                                                |
|-----------|-------------------------------------------|---------------------------------------------------|--------------------------------------------------------------------------|
| REST      | [User doc](client-libraries-rest.md)      | [Bundled](pathname:///release-notes/)             | [Bundled](https://github.com/apache/pulsar/tree/master/pulsar-broker)    |
| WebSocket | [User doc](client-libraries-websocket.md) | [Standalone](pathname:///release-notes/client-ws) | [Bundled](https://github.com/apache/pulsar/tree/master/pulsar-websocket) |

## Feature matrix

Pulsar client feature matrix for different languages is listed on [Pulsar Feature Matrix (Client and Function)](https://docs.google.com/spreadsheets/d/1YHYTkIXR8-Ql103u-IMI18TXLlGStK8uJjDsOOA0T20/edit#gid=1784579914) page.

## Third-party clients

Besides the officially released clients, multiple projects on developing Pulsar clients are available in different languages.
