Marqo

End-to-end vector search engine with built-in embedding generation.

Marqo is an open-source, end-to-end vector search engine that handles embedding inference and storage in one system, so you index raw text and images rather than precomputed vectors. It supports multimodal search, tensor-based retrieval, and horizontal scaling, removing the need to wire a separate embedding pipeline in front of a bare vector store. It is notable for turning the whole 'embed then store then query' pipeline into a single API.
