The honest brief
Haystack
More production-oriented and explicitly composable than lighter agent libraries: typed pipelines give direct control over retrieval, routing, and memory.
- Composable, typed pipeline architecture
- Model- and vector-store agnostic
- Strong production tooling
- Mature docs and integrations
- Pipeline model has a learning curve
- Python-only
- Heavier than minimal agent libraries
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
