LlamaIndex
Framework for connecting LLMs and agents to your own documents and data.
Retrieval-heavy applications where the hard part is getting your own documents and data into an agent reliably.
Your agent does not read private data, in which case most of the framework goes unused.
About LlamaIndex
LlamaIndex provides ingestion, indexing, retrieval and query engines for building RAG and agent applications over private data, plus workflow primitives for multi-step agents. The open-source Python framework is MIT licensed; LlamaCloud and LlamaParse are the company's separate hosted, paid services.
LlamaIndex is listed in this index, with 53k stars on GitHub. Its latest recorded repository push was in October 2026; that is not an ASE editorial review date.
