Vector databases provide storage and retrieval capabilities for applications that work with vector data. Compare deployment choices, index types, and maximum dimensions, then check whether hybrid search, sparse vectors, or metadata filtering match your retrieval requirements. SDK languages are useful to consider alongside your existing stack, while a free plan and paid-from price help frame access and cost. Chroma, Vespa, and Qdrant are among the entries. Weigh the capabilities specified for each database against the workloads and integration needs you have.
