---------------------- LlamaIndex is a Python library, and it is primarily designed to be integrated with Python-based backend servers. For instance, in the Full-Stack Web Application Guide (), it is demonstrated how to use LlamaIndex with a Flask server, which is a popular Python web framework.
In another example, the Delphic Full-Stack Application Guide () shows how to use LlamaIndex with Django, another Python web framework.
Therefore, Python would be the recommended backend language to use with LlamaIndex due to its native compatibility and the availability of resources and examples. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
