Turbopuffer - Pros & Cons
Pros
- ✓10x cheaper than traditional vector databases at scale due to object storage-first architecture instead of RAM-heavy designs
- ✓Sub-10ms p50 latency for warm queries rivals in-memory databases while maintaining dramatically lower costs
- ✓Native BM25 full-text search and hybrid search combine semantic and keyword retrieval without needing separate search infrastructure
- ✓Unlimited namespaces with automatic scaling makes it ideal for multi-tenant SaaS applications with thousands of customers
- ✓Proven at extreme scale: 2.5T+ documents, 10M+ writes/s in production — not just benchmarks
Cons
- ✗$64/month minimum commitment can be expensive for small projects or hobbyists compared to free tiers on Pinecone or Qdrant
- ✗Cold namespace queries have significantly higher latency (~343ms p50) which may not suit real-time applications accessing infrequently-used data
- ✗Not open source — no self-hosted option for teams that need full control over their infrastructure
- ✗Write latency is higher than in-memory databases (p50 >200ms), which can be a bottleneck for write-heavy workloads
Weaviate - Pros & Cons
Pros
- ✓Combines vector, keyword, and hybrid retrieval
- ✓Offers managed and self-hosted deployment
- ✓Free cloud tier supports prototyping
- ✓Publishes baseline and metered prices
Cons
- ✗Retrieval quality requires careful evaluation
- ✗Cloud cost has several usage dimensions
- ✗Self-hosting transfers operations to the team
- ✗Authorization-safe RAG needs more than a database
