Pros
  • Unifies graph, vector, and full-text search in one query layer
  • Object-storage backend keeps costs and ops overhead lower than hot-memory stores
  • Open source with SDKs in Rust, Go, TypeScript, and Python
  • Temporal awareness for facts that change over time, useful for agent memory
  • Focused on retrieval (not general agent stuff)
  • Many ingestion connectors
  • Strong production patterns
  • LlamaCloud for managed ingestion
Cons
  • Younger project than Pinecone/Weaviate/Neo4j; smaller ecosystem and tooling
  • Pricing for managed tier not transparent on the marketing site
  • Object-storage tradeoffs may add latency vs in-memory vector DBs for hot paths
  • API surface is large
  • Documentation can be hard to navigate
