LlamaIndex in brief

Open-source data framework for retrieval-augmented generation and document-centred agents, with a hosted document platform alongside.

LlamaIndex's repository is MIT-licensed with release v0.14.25 tagged Sep 21, 2026 and recent pushes in October 2026. It focuses on connecting LLMs to your data: loaders, indexes, query engines and agent workflows.

What it does well: Strong data-ingestion focus; MIT license.

Where it falls short: Hosted product pricing not read here; Our test was one small task on a local 3B model; it does not show behaviour with hosted models or larger jobs.

Latest version we cover: v0.14.25 (Sep 21, 2026). Vendor: LlamaIndex.

When to look beyond LlamaIndex

Skip LlamaIndex if:

You need a general multi-agent orchestrator rather than data tooling
