What it is
A structured comparison of 11 vector databases for retrieval-augmented generation (RAG) across five dimensions: deployment shape, open-source license, native hybrid search, metadata filtering, and pricing model. Compiled vendor-neutral with conflict disclosure; each cell read from the vendor's own repository, documentation, or pricing page. The thesis: hybrid search and filtering are now table-stakes, so the deciding axis is deployment shape and data gravity, not benchmark.
