Best ForAI-native developer experience — the fastest path from `pip install` to a working RAG prototype, with a managed cloud when you're ready
Hybrid RAG with built-in vectorizer modules, generative search, and strong multi-tenancy — runs anywhere from laptop to managed cloud
LimitationsYounger than Pinecone or Weaviate at scale; fewer index tuning knobs (HNSW only); compliance certifications are still maturing
Resource-hungry compared to Qdrant or Chroma; module configuration has a learning curve; some advanced replication features are cloud-only
