Other Languages
---------------

There are many other programming languages that provide |ak| client libraries as well. 
Refer to :ref:`clients-all-examples` for client examples written in the following programming languages and tools.
These "Hello, World!" examples produce to and consume from any |ak| cluster, and for the subset of languages that support it, there are additional examples using |sr-ccloud| and Avro.
