Best ForProduction RAG and agent memory at scale — serverless billing, generous free tier, and a managed experience with zero ops
Hybrid RAG with built-in vectorizer modules, generative search, and strong multi-tenancy — runs anywhere from laptop to managed cloud
LimitationsCloud-only with no self-hosted option; vendor lock-in on proprietary index format; advanced features like dedicated read nodes add cost quickly at scale
Resource-hungry compared to Qdrant or Chroma; module configuration has a learning curve; some advanced replication features are cloud-only
