turbopuffer is a vector and full-text search engine built on object storage (Amazon S3), designed for AI/ML engineers who need high-scale similarity search at a fraction of the cost of traditional vector databases. It supports vector search, BM25 full-text search, and hybrid search with metadata filtering — all backed by an API-first architecture.
Key technical characteristics:
- Storage layer: Built directly on Amazon S3, enabling near-unlimited horizontal scalability
- Scale benchmarks: Supports 1T+ documents, 10M+ writes/second, and 100k+ queries/second
- Latency: Sub-10ms p50 for warm namespaces
- Search capabilities: Vector similarity search, BM25 full-text search, hybrid search, and metadata filtering
- Automatic scaling: No manual cluster management required
- API available: Yes
- Open source: Yes (52 GitHub stars)
- Pricing model: Usage-based — Storage ≤$0.33/GB, Writes ≤$2.00/GB, Queries ≤$1.00/PB; plans start at $16/mo (Launch)
