Alternatives to turbopuffer
Serverless vector and full-text search on object storage
turbopuffer ranks #9 of 9 in Vector databases, with an Alt Score of 68. It is proprietary and available on the web. 13 of 13 checklist rows are verified against a public source.
turbopuffer is a serverless vector and full-text search database built on object storage, offered as a managed cloud service.
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.
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.
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.
https://turbopuffer.com/pricing -
Starts at $16/month verified 2026-07-16
$16/month is the minimum usage charge on the cheapest (Launch) plan; there is no free paid tier.
Launch plan minimum reduced from $64 → $16/month

Hybrid search (vector + keyword) Yes verified 2026-07-16
turbopuffer supports vector search (for semantic relevance) and BM25 full-text search (for exact keyword matching).
https://turbopuffer.com/docs/concepts -
Metadata filtering Yes verified 2026-07-16
Filtering allows queries to restrict results to documents matching specific attribute conditions.
https://turbopuffer.com/docs/concepts -
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.
https://turbopuffer.com/docs/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.
