Best ForTeams already on MongoDB who want vector search next to operational data — one driver, one query language, one backup story
Production RAG and agent memory at scale — serverless billing, generous free tier, and a managed experience with zero ops
LimitationsVector indexes are tied to Atlas (not self-hosted Community Server); search nodes add cost; index build times can be long for large collections
Cloud-only with no self-hosted option; vendor lock-in on proprietary index format; advanced features like dedicated read nodes add cost quickly at scale
