Highlighted rows are where these differ.
Redis
- Practical to roughly 10 to 100 million vectors
- You are paying for RAM, which sets the ceiling
Best for caches and hot vector sets.
Qdrant
- Written in Rust; 10 to 25% faster than Weaviate or Milvus on common workloads
- Strong filtering alongside vector search
- Self-host or managed, same engine
Best for latency-sensitive retrieval.
Pinecone
- Sub-10ms p50 with nothing to maintain
- Costs draw scrutiny at scale; Notion moved away and cut spend ~60%
Best for teams who do not want to run a database.
