RAG and search: tools for developers

Retrieval-augmented tools, vector databases, embeddings and semantic search. An entry can appear under several use cases when its topics or description provide several explicit signals.

Tool ranking

Ranked by creation date, newest first; undated entries come last. Raw values keep their source-specific window, shown under each tool; a change requires at least two snapshots from the last 7 days.
