overview

What is turbopuffer?

turbopuffer is a serverless vector and full-text search engine developed by Simon Hørup Eskildsen and Justine Li that enables AI developers, startups, and large enterprises to perform fast, scalable, and cost-effective data retrieval. It distinguishes itself through an object storage-native architecture, which significantly reduces costs compared to traditional in-memory vector databases while maintaining high performance for AI applications.

Turbopuffer provides fast, scalable, and cost-effective vector and full-text search capabilities. It is built from first principles on object storage (Amazon S3, Google Cloud Storage, Azure Blob Storage) with a tiered caching system (NVMe SSDs and RAM) to balance cost and performance. The platform is currently handling over 4 trillion documents, 10 million writes per second, and 25,000 queries per second in production systems. Recent updates include the introduction of i8 vector types in June 2026 for quantization-aware models, reducing storage and query cost by 75% compared to f32, and Namespace Branching in May 2026 for instant copy-on-write namespace cloning.

use cases

Who Should Use turbopuffer?

turbopuffer is designed for organizations and developers requiring scalable, cost-effective search solutions for AI-driven applications.

  • AI Developers: For connecting Large Language Models (LLMs) to vast amounts of unstructured data through Retrieval Augmented Generation (RAG).
  • Startups: Seeking a serverless, managed solution to scale AI applications without significant infrastructure overhead.
  • Large Enterprises: Requiring efficient, large-scale data retrieval and semantic search across billions of documents.
  • Companies Building AI Applications: For implementing semantic search, recommendation systems, and hybrid search functionalities.

pricing

turbopuffer Pricing & Plans

turbopuffer operates on a paid, usage-based business model, emphasizing cost-effectiveness, often cited as 10x to 100x cheaper than traditional in-memory vector databases. Pricing is calculated based on usage, with specific costs for storage, writes, and queries. Users can calculate their price for turbopuffer's vector and full-text search via the platform's tools.

API rate limits are enforced to maintain system stability and performance. Users may encounter an HTTP 429 error if query or write operations occur too quickly. Specific limits include a maximum global write throughput of 10M+ writes/s at 32GB/s. For writes, there is a limit of one WAL entry per second per namespace; if a new batch is started within one second of the previous one, it will take up to 1 second to commit. Additionally, once a namespace has more than 128MiB of outstanding writes, further writes are not visible until they are indexed and loaded into cache. Query pricing was reduced by up to 94% for the largest namespaces in February 2026. While cold queries can take 200-500ms, warm queries achieve sub-10ms p50 latency.

Similar Tools

turbopuffer vs Competitors

turbopuffer differentiates itself in the vector database market primarily through its object storage-native architecture, which enables significant cost savings and massive scalability compared to many alternatives.

1
PineconeOn StorkCompare

Pinecone is a fully managed vector database purpose-built for similarity search and retrieval-augmented generation (RAG) in AI applications.

Like Turbopuffer, Pinecone is a managed service focused on high-performance vector search and uses object storage for persistence. However, Turbopuffer emphasizes its object storage-native architecture for potentially lower costs, especially for cold data, and offers integrated full-text search.

2
QdrantOn StorkCompare

Qdrant is an open-source, high-performance vector database written in Rust, optimized for speed, reliability, and advanced filtering with payload indexes and quantization techniques.

Qdrant offers both open-source and managed cloud options, providing deployment flexibility that Turbopuffer, as a managed-only service, does not. Both focus on scalable vector search and utilize object storage for persistence, but Qdrant's open-source nature allows for self-hosting.

3
Milvus (Zilliz Cloud)On StorkCompare

Milvus is an open-source vector database built for scalable similarity search, capable of handling billions of vectors, with Zilliz Cloud providing a fully managed enterprise-grade version.

Milvus, similar to Turbopuffer, is designed for large-scale vector search and leverages object storage for data persistence. While Turbopuffer is a managed service, Milvus offers an open-source option for self-hosting, and Zilliz Cloud provides a managed service with a distinct architecture.

4
ChromaOn StorkCompare

Chroma is an open-source embedding database designed for simplicity and developer experience, built on object storage with automatic data tiering for cost and performance.

Chroma shares Turbopuffer's emphasis on being built on object storage for cost-effectiveness and scalability, and offers both vector and full-text search capabilities. However, Chroma is open-source, providing self-hosting options, whereas Turbopuffer is exclusively a managed service.
