The honest brief
Chroma
Runs embedded inside your Python process — the lowest-friction way to prototype RAG before you need a server at all.
- Pip-install, embedded in-process
- Minimal setup for prototyping
- Open-source
- Hosted option when you outgrow local
- Not built for massive scale
- Fewer enterprise features than rivals
- Python-centric ergonomics
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
When to pick which
Both cover Vector search.
