Event-driven workflows and the data layer for retrieval-heavy agents.

Source Docs Website

Overview

LlamaIndex began as a retrieval framework and grew into event-driven agent workflows, but its centre of gravity is still data: ingestion, chunking, indexing, and querying across hundreds of connectors. It is the pragmatic choice when the hard part of the agent is the corpus rather than the control flow.

Why it's indexed

The deepest connector and indexing surface when retrieval quality is the bottleneck.

Editorial judgement, not a measurement — see our methodology. Listing is never paid for.
