turbopuffer

turbopuffer is a serverless search engine that combines vector and full-text (BM25) search built from first principles directly on object storage. It exposes a single REST API organized around namespaces — each namespace stores documents with vector embeddings, attributes, and full-text indexes — and supports approximate nearest neighbor, full-text BM25, and hybrid query patterns with attribute filtering, ranking, and aggregation. The platform is used in production by Anthropic, Cursor, Notion, Linear, Superhuman, Pylon, Readwise, and Telus, and handles 4T+ documents, 10M+ writes/s, and 25k+ queries/s across customer fleets. Official client libraries ship for Python, TypeScript, Go, Java, Ruby, and C#, generated from a public OpenAPI 3.1 specification via Stainless. Pricing is tiered (Launch, Scale, Enterprise) with usage-based metering on storage, writes, and queries on top of monthly minimums.

turbopuffer publishes 1 API on the APIs.io network: Namespaces API. Tagged areas include Vector Search, Full-Text Search, Hybrid Search, BM25, and Serverless.

turbopuffer’s developer surface includes authentication, documentation, GitHub presence, pricing, engineering blog, and 11 more developer resources.
