The honest brief
Turbopuffer
Indexes live on object storage, not RAM, so cost tracks usage not corpus size — built for huge, mostly-cold vector workloads.
- S3-like billing: cold rest, warm reads
- Scales to very large, cold corpora
- No per-namespace minimums
- Proven at Notion production scale
- Cold reads have higher latency
- Paid-only, no free self-host
- API-only, no managed UI
- Less mature ecosystem than peers
Upstash Vector
Pay-per-request serverless pricing and an optional built-in embedding model, so small RAG apps run at near-zero idle cost with no cluster to manage.
- Serverless, pay-per-use pricing
- Simple REST API + Python/TS SDKs
- Optional built-in embedding models
- Metadata filtering on queries
- Free tier to start
- Managed-only; not self-hostable
- Proprietary, not open source
- Fewer index controls than dedicated DBs
