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
Milvus
Storage/compute split plus DiskANN make it the most robust open-source choice at billion-vector scale.
- Scales to billion-vector deployments
- Storage/compute separation
- Many index types (HNSW, IVF, DiskANN) + GPU
- Mature project with a large community
- Operationally heavy to self-host
- Overkill for small workloads
- Performance hinges on data quality
- Higher latency than Qdrant at p50
