Vespa is an open-source big-data serving engine for search, recommendation and vector retrieval, with Vespa Cloud as the managed option.
Vespa is aimed at engineering teams building large-scale search, recommendation, RAG, and personalization systems that need to combine vector search, text search, and structured filtering with low-latency serving.
Vespa is an open-source (Apache 2.0) big-data serving engine with built-in approximate nearest-neighbor vector search, hybrid (vector + keyword) retrieval, machine-learned ranking, and real-time partial updates, which you can self-host or run on the managed Vespa Cloud.
Documents, including vector/tensor fields, text, and structured data, are indexed across horizontally scalable content clusters; queries use Vespa's YQL query language to combine nearest-neighbor search, text matching, and filters, with ranking computed locally on the nodes holding the data for speed at scale.
