LlamaIndex
LlamaIndex is an open-source Python framework for building agentic applications, developed alongside LlamaParse, the company's own platform for agentic document parsing, extraction and indexing.
The OSS framework offers a starter package bundling core LlamaIndex with a selection of integrations, or a core package that a developer combines with specific integration packages, of which more than three hundred exist, for a chosen LLM, embedding model and vector store. LlamaParse is a separate, focused platform covering agentic OCR and parsing across more than 130 document formats, structured data extraction, splitting large documents, and building end-to-end document agents with a workflow builder, usable either standalone or together with the OSS framework.
The README states that the company's current focus has shifted from the general-purpose orchestration framework toward document parsing and extraction as agents increasingly become the primary consumers of documents.
