Turbopuffer vs Vespa: Vector Databases Comparison

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.

Vespa is an AI-powered search platform for developing and operating large-scale applications that combine big data, vector search, machine-learned ranking, and real-time inference. Originally developed at Yahoo and spun out as an independent company in 2017, Vespa enables real-time AI applications like RAG, recommendation, and intelligent search at enterprise scale. The platform features native tensor support for complex ranking and decisioning, with capabilities including vector and tensor search with any number of vector fields, true positional text indexes with detailed text match features, and hybrid search combining structured filters, full-text retrieval, and vector similarity in a single query. Vespa can scale to billions of constantly changing data items, handling thousands of queries per second with latencies below 100 milliseconds. Based in Trondheim, Norway, Vespa raised $31M in Series A funding in November 2023.
