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.

  • Pricing model Usage-based verified 2026-07-16

    Storage, writes, queries, and embeddings are all metered and billed by consumption, with a monthly minimum usage charge per plan (e.g. $16/month on Launch).

    Queries are billed as the sum of two components: the amount of data queried and the amount of data returned.

  • Horizontal scaling / sharding Partial verified 2026-07-16

    Query/indexing compute nodes auto-scale with demand (docs/concepts), but a single namespace is capped at 500M docs/2TB, so scaling beyond that requires manual application-level sharding across namespa

    Requires manually sharding into multiple namespaces (e.g. id % N) to comply with per-namespace limits.

  • Serverless option Yes verified 2026-07-16

    turbopuffer never uses the literal word 'serverless', but its only offering is a pay-per-use API backed by stateless, auto-scaling compute with no servers to provision or manage.

    Compute nodes are stateless. This means any node can serve queries for any namespace.
