turbopuffer
Vector databasesA serverless vector and full-text search engine built on object storage for low cost.
turbopuffer is built on a different cost model: it keeps data on cheap object storage and caches hot data, rather than holding everything on expensive memory or SSD. The result is dramatically lower cost for large but not constantly-hot datasets.
It does vector and full-text search together, and is fully managed.
Where it's ideally used
A fit for large search workloads where cost matters and not all of the data is hot at once.
Where it doesn't fit
A managed service — not the choice when data must stay self-hosted; and pure in-memory stores still win on raw latency.
