Redis Vector Search
FreemiumVector similarity search built into Redis — low-latency embeddings at scale.
Tool Info
Overview
Redis Vector Search extends Redis with vector indexing and similarity queries.
Teams already on Redis can add RAG retrieval without a separate database.
Strong for real-time apps needing cache co-location with embeddings.
