Turbopuffer
Vector & full-text search on S3: 10x cheaper, auto-scaling
For large-scale vector search where cost dominates, turbopuffer wins by decoupling compute from storage. Cold-namespace latency is the trade-off, but for most batch and long-running workloads, the savings blow past Pinecone or Weaviate.

About Turbopuffer
Turbopuffer is a vector and full-text search database built on object storage (S3) that delivers sub-10ms p50 latency, automatic scaling, and 10x cost savings versus traditional vector databases. Designed for AI applications, semantic search, and recommendation systems, it supports billions of vectors, hybrid search combining vector embeddings with BM25 full-text, and metadata filtering. Trusted by Cursor, Anthropic, Notion, Atlassian, and others, it handles 4T+ documents, 10M+ writes/s, and 25k+ queries/s in production. Key features include i8 vector quantization for 75% cheaper storage vs. f32, sparse vector search, a 3x faster word_v4 tokenizer, and a Fuzzy filter for typo-tolerant string matching. The new instant copy-on-write namespace branching enables easy testing and experimentation. Namespace pinning caches hot data to reduce costs at high QPS. Pricing starts at $16/month minimum usage on the Launch plan, with Scale at $256/month and Enterprise at $4,096/month. All plans include the same database features; higher tiers add compliance, support, and deployment options. Unlike alternatives like Pinecone or Weaviate, turbopuffer replaces expensive compute nodes with cheap object storage, making it ideal for cost-sensitive, high-scale AI workloads.
Behind the Verdict
Turbopuffer's core insight—running search on object storage—is what makes it 10x cheaper. In practice, we'd choose it for any RAG system or recommendation engine with billions of vectors where you can tolerate occasional cold-start latency (sub-10ms p50 when warm). Where it bites: If your workload demands sub-5ms p99 on every query (cold namespace), you'll need to pin hot namespaces (256 max) or accept the slower first access. Teams with under 100k vectors should look at simpler options like Supabase pgvector or LanceDB—turbopuffer's minimum $16/month fee and architectural complexity aren't justified at tiny scale. For enterprises needing compliance, the Enterprise tier ($4,096+/month) brings single-tenancy, BYOC, CMEK, HIPAA, and 99.95% SLA—positions it well against Pinecone's enterprise offering. The recent price drop (Launch minimum from $64 to $16) lowers the barrier, but you still pay per GB stored and per query; monitor usage carefully. Compared to alternatives: Pinecone is simpler to start but gets expensive fast; Weaviate offers more features (hybrid search, generatives) but costs similarly. Turbopuffer's trade-off is storage-backed latency for drastically lower spend—a fair exchange for cost-optimized pipelines.

Real-world workflow fit
Concrete scenarios for the personas Turbopuffer actually fits — and what changes day-one when you adopt it.
You need to index 10 million support documents and perform hybrid vector + keyword search with high throughput.
Outcome: Turbopuffer ingests data at 10M writes/s globally, enables sub-10ms p50 queries on warm cache, and costs 10x less than Pinecone or Weaviate.
You have petabytes of documents and need to test ranking changes without duplicating data.
Outcome: Use namespace branching to create instant copy-on-write clones, run experiments independently, and deploy improved search at scale.
You have billions of embeddings and need to cut infrastructure costs while maintaining performance.
Outcome: Enable i8 quantization to reduce storage and query cost by 75% compared to f32, and pin frequently accessed namespaces to cache for lower cost at high QPS.
Use Cases
- Search across millions of support tickets with hybrid vector + BM25 search.
- Build a cost-effective semantic search for a knowledge base storing billions of embeddings.
- Power the retrieval stage of a RAG pipeline for an AI assistant with high write throughput.
- Implement recommendation systems with metadata filtering and vector similarity.
- Enable fast full-text search with typo tolerance for a product catalog.
- Use namespace branching to test search ranking changes without duplicating data.
- Serve as a first-stage retriever for agentic AI workflows requiring high QPS.
Limitations
- Cold queries (when data is not in cache) can take p90 >1s, making turbopuffer less suitable for latency-sensitive applications that require instant responses on every query.
- The number of pinned namespaces is limited to 256 by default (custom limits available on Enterprise).
- Full-text search query length is capped at 8,192 characters.
- Maximum documents per namespace is 500 million (with 2TB storage), though global totals can be much higher.

Turbopuffer's pricing is ideal for AI teams with large-scale vector workloads: the Launch plan's $16/month minimum (reduced from $64 in June 2026) makes it cheaper than Pinecone's free tier limits. Scale at $256/month suits medium teams, while Enterprise at $4,096/month + 35% premium targets heavy users. For tiny projects, Serverless options from other vendors may be simpler.
Setup time & first value
How long it actually takes to get something useful out of Turbopuffer — broken out by persona, not the marketing-page minute.
For a developer with basic API experience: 15 minutes to first query via the Quickstart. New users can sign up, create a namespace, upsert documents, and run hybrid search without any infrastructure setup. Teams migrating from another vector database should allocate 1–3 days to adapt indexing pipelines and tune cache pinning.
Switching to or from Turbopuffer
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Pinecone: export vectors as JSON, use turbopuffer's write API to upsert, then adjust query code for hybrid search syntax.
- →From Weaviate: export using Weaviate's batch export, transform schema to turbopuffer's attribute model, and reindex.
- ↗To Pinecone: export documents via turbopuffer's export warm cache API, then batch upload to Pinecone.
- ↗To Weaviate: use turbopuffer's export endpoint and Weaviate's bulk import, noting schema differences.
