The honest brief
LanceDB
Runs in-process on the disk-efficient Lance format — no server, no port, zero-copy reads; strong on multimodal data.
- Embeds in your app; runs on edge/desktop
- Disk-efficient Lance format, low cost
- Native multimodal (text, image, video)
- Hybrid vector + full-text + SQL queries
- Newer; smaller community than Qdrant/Milvus
- Managed cloud tier still maturing
- Multi-process concurrent access limits
- Fewer framework integrations, less tooling
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
