About Vespa
Vespa is an open-source engine that was originally built to power big search and recommendation systems. It supports vector search, full-text search and structured filtering in a single query, along with machine-learned ranking.
That combination makes it strong for applications where results need to be ranked with several signals at once, such as e-commerce and large-scale retrieval for AI. It scales across many nodes and updates data in real time.
Vespa is free to self-host, and Vespa Cloud is a managed option with usage-based pricing. It is aimed at engineering teams with demanding search needs.
