About Turbopuffer
Turbopuffer is a serverless vector and full-text search database trusted by leading companies including Notion, Cursor, Linear, and PlayerZero. Founded in 2023 by ex-Shopify engineers Simon Eskildsen and team, Turbopuffer reached $1 million in ARR within a year of launch and now operates profitably with only 22 employees while powering billions of vectors. The platform features serverless architecture with automatic scaling, sub-10ms p50 latency, support for billions of vectors, full-text search, hybrid search, and metadata filtering. TurboPuffer achieves up to 100x cost reduction compared to traditional vector databases by storing data on object storage like S3 at $0.02 per GB instead of in-memory at $2+ per GB. Turbopuffer has no enforced namespace limits and includes enterprise-grade compliance features like HIPAA BAA, SOC 2, and CMEK even on the non-enterprise plan. Query prices have been reduced by up to 94%, making it 10x-100x cheaper than alternatives with usage-based pricing.
About Weaviate
Weaviate is an open-source vector database that combines vector search with structured filtering and generative capabilities. It supports multiple vectorization modules, hybrid search (combining BM25 and vector search), and built-in integrations with LLMs for retrieval-augmented generation. Weaviate offers both self-hosted and managed cloud deployments, with a GraphQL API that makes it easy to query complex data structures.
What is Vector Databases?
Purpose-built databases for storing, indexing, and querying high-dimensional vector embeddings used in semantic search, RAG, and recommendation systems.
