## Overview

- **Who it's for**: turbopuffer targets engineering teams building large-scale vector, full-text, and hybrid search applications (RAG, semantic search, recommendations) who want a managed, object-storage-native database instead of operating their own vector search infrastructure, from small usage-based projects up through enterprises needing BYOC, SSO, HIPAA, and SOC 2 compliance.
- **What you get**: A cloud API for vector similarity search (SPFresh ANN index) and BM25 full-text search combined into hybrid search, with metadata filtering, unlimited namespaces for multi-tenancy, copy-on-write namespace branching, strongly consistent real-time upserts, and private-beta native embedding generation, priced by usage (storage, writes, queries) with a monthly minimum starting at $16/month on the Launch plan.
- **How it works**: All durable data lives in object storage (S3/GCS/Azure Blob) as a write-ahead log plus an object-storage-native LSM tree; writes are group-committed to the WAL and then asynchronously indexed, while stateless, auto-scaling query and indexing nodes cache namespace data on NVMe SSD and in memory so that repeated queries to a namespace become fast after an initial cold read from object storage.
