The best vector databases for RAG
#8 this week, scoring 7.3 out of 10. Best for Teams already using Redis who need fast vector search with low latency and want to consolidate infrastructure.
- Query performance 8
- Very fast queries due to in-memory architecture, excellent for low-latency requirements at moderate scale.
- Ease of deployment 8
- Easy deployment especially for Redis users, though requires Redis Stack or modules installation.
- Metadata filtering 7
- Supports tag and numeric filtering with queries but less flexible than full SQL or advanced query DSLs.
- Scalability & cost 5
- In-memory architecture makes large-scale deployments expensive; cost scales linearly with data size.
- Ecosystem integration 7
- Growing support in RAG frameworks with Redis's popularity helping adoption.
