    For a new self-hosted semantic-search application, I’d start with Qdrant. It gives a particularly good balance of search features, performance, straightforward deployment, metadata filtering, and operational simplicity. Qdrant is specifically designed around vector/semantic retrieval and supports filtering, hybrid retrieval, quantization, multitenancy, and both dense and sparse vectors. ([qdrant.t

What you are reading

  • Excerpts — at most 400 characters — of AI engine responses to standardised buyer prompts. Never full answers.
  • Index measurements only. Customer scans are never archived here, at any granularity.
  • Highlighted names are the products the extractor recorded in that answer. A mention is not an endorsement, and this page ranks nothing — the ranking does that, with sample sizes.
  • Engines whose terms do not permit republishing generated text appear with their excerpt withheld, never hidden.
