The honest brief

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

RAGFlow

DeepDoc parsing turns messy PDFs, tables, and scans into citation-backed chunks—grounding answers better than naive text-splitting RAG stacks.

  • Apache-2.0, fully self-hostable
  • Deep document, table, and scan parsing
  • Hallucination-resistant grounded QA
  • Hybrid vector + full-text search
  • Built-in agent orchestration
  • Heavier setup than hosted RAG APIs
  • Cloud tiers cap apps and storage
  • Resource-intensive to self-host
