Best ForAI-native developer experience — the fastest path from `pip install` to a working RAG prototype, with a managed cloud when you're ready
High-performance vector search with rich payload filtering — Rust-written, predictable latency, and a clean self-hosted path
LimitationsYounger than Pinecone or Weaviate at scale; fewer index tuning knobs (HNSW only); compliance certifications are still maturing
No built-in embedding generation — bring your own embeddings; managed cloud is younger than Pinecone's; fewer turnkey RAG modules than Weaviate
