Agent-native side-by-side. Scores are curated estimates on a 0–10 scale. Lock-in: higher = worse. Prefer JTBD picks via /api/decide when choosing for a job.
| Dimension | Chroma | Supabase (pgvector) |
|---|---|---|
| Overall | 7.9 | 8.6 |
| Capability fit | 7.2 | 8.5 |
| Price / performance | 9.0 | 9.0 |
| Latency / reliability | 7.0 | 8.6 |
| Developer & agent DX | 9.2 | 9.4 |
| Privacy / data retention | 7.5 | 8.0 |
| Lock-in risk (higher = worse) | 2.5 | 3.0 |
| Maturity / track record | 7.5 | 9.0 |
| Pricing | As of 2026-09-14: Open-source embeddable vector DB + hosted Chroma Cloud; free/local for prototypes; Cloud usage-based for managed. Excellent DX for demos; graduate before high QPS/filtered production. | Postgres + pgvector + Auth + Storage; usage on compute/storage; free tier. Vectors hitchhike on Postgres. |
| Tagline | Prototype on Chroma; graduate to Qdrant/pgvector/Pinecone before your corpus and QPS grow up. | Depot default for most agent apps under ~25–50M vectors. Don't add Pinecone until Postgres actually hurts. |
Chroma
Prototype on Chroma; graduate to Qdrant/pgvector/Pinecone before your corpus and QPS grow up. Strengths: Fastest path to local RAG prototype; Python-native DX; Good for demos and notebooks.
Strengths
- Fastest path to local RAG prototype
- Python-native DX
- Good for demos and notebooks
Weaknesses
- Not the scale leader vs Qdrant/Milvus/Pinecone
- Production features still catching up
- Hosted maturity evolving
Supabase (pgvector)
Depot default for most agent apps under ~25–50M vectors. Don't add Pinecone until Postgres actually hurts. Strengths: One backend for auth, DB, storage, vectors; Best DX for many Next.js agent apps; Open standards (Postgres).
Strengths
- One backend for auth, DB, storage, vectors
- Best DX for many Next.js agent apps
- Open standards (Postgres)
Weaknesses
- Vector scale ceiling vs dedicated engines
- Need pgvectorscale/careful indexing past tens of M
- Not a pure vector specialist
