LightRAG builds a knowledge graph over your documents and retrieves across it, which handles questions spanning many sources better than plain vector search. Both the LLM and the embedding model are configurable: OPENAI_API_KEY, Gemini or a local Ollama, meaning the whole pipeline can run with no cloud key at all. That matters more here than in a chat tool, because indexing sends every document you own through a model rather than just the question you asked. MIT.

How this tool was scored

Key handling 88/100 (where your key rests and who sees it, comparable across any licence) and verifiability 90/100 (how much of that BYOAIK could confirm, lower for closed source). Neither contains a popularity signal.

  • Key Safety 22/25: The key is supplied by an environment variable or local config file you control.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under MIT, so anyone can check how the key is handled. Key handling was located in the published source.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 7/10: Key handling was found in the published source by BYOAIK's scanner.

What was checked

Verification tier SOURCE_VERIFIED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] The user supplies their own OpenAI key: the project references its API key variable. source
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [CONFIRMED · SOURCE_SCAN] Ships a container definition, so it can be self-hosted on your own infrastructure. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-09-26, about 0 month(s) ago. source

How your API key is handled

Your API key is supplied via an environment variable or local config file. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
