Pros
  • Incremental reprocessing keeps indexes sub-second fresh without full reruns
  • AST-aware code indexing with call graphs, not just naive text chunking
  • Open source and self-hosted; works with Postgres/pgvector
  • Declarative Python API with lineage and schema evolution built in
  • Focused on retrieval (not general agent stuff)
  • Many ingestion connectors
  • Strong production patterns
  • LlamaCloud for managed ingestion
Cons
  • Self-hosted only - you operate the database, embeddings, and LLM yourself
  • Python-only framework; no managed cloud or hosted UI
  • Younger ecosystem than LlamaIndex or LangChain
  • API surface is large
  • Documentation can be hard to navigate
