The honest brief

LibreChat

Multi-user auth built in — the closest to a self-owned, team-wide ChatGPT across every provider.

  • Unifies many providers in one UI
  • Agents, code, RAG, web search
  • Runs on your own infrastructure
  • BYO keys or local endpoints
  • Self-host + Docker setup needed
  • BYO model keys (usage costs)
  • Maintenance burden on you

Onyx

Formerly Danswer — MIT-core enterprise search/RAG over your own apps, self-hosted, optional features under open-core.

  • Data stays on your own infrastructure
  • Connects to company docs and apps
  • Works with any LLM, incl. local
  • MIT core, free
  • Some features under separate license
  • Self-host ops overhead
  • Connectors need configuration
