Object-storage vector + FTS DB

PaidSearch, vector & RAGturbopuffer.com

What it is

A search database that keeps data on object storage such as S3, with memory and SSD caching in front — which is where its claim of roughly 10x lower cost than in-memory vector DBs comes from. Does vector and full-text search with filtering in one query, scaling a namespace to 256TB.

Why it earns a slot

Built for the shape where you have millions of tenants who each search rarely — an idle namespace costs almost nothing. Anthropic, Notion, Linear and Grammarly run production search on it.

Know before you commit

No free tier and a $16/mo floor, so it is not a weekend-project database. Cold namespaces pay a first-query latency penalty while data loads from object storage.
