| Dimension | Neon | Supabase (pgvector) |
|---|---|---|
| Overall | 8.6 | 8.6 |
| Capability fit | 8.6 | 8.5 |
| Price / performance | 8.8 | 9.0 |
| Latency / reliability | 8.6 | 8.6 |
| Developer & agent DX | 9.4 | 9.4 |
| Privacy / data retention | 8.2 | 8.0 |
| Lock-in risk (higher = worse) | 3.0 | 3.0 |
| Maturity / track record | 8.5 | 9.0 |
| Pricing | Serverless Postgres with branching; pgvector supported; usage-based compute/storage. | Postgres + pgvector + Auth + Storage; usage on compute/storage; free tier. Vectors hitchhike on Postgres. |
| Tagline | Excellent serverless Postgres for agent apps that want branching + pgvector without Supabase's full BaaS. | Depot default for most agent apps under ~25–50M vectors. Don't add Pinecone until Postgres actually hurts. |
Neon
Excellent serverless Postgres for agent apps that want branching + pgvector without Supabase's full BaaS. Strengths: Serverless Postgres DX; Branching for previews/agents; pgvector without managing Postgres.
Strengths
- Serverless Postgres DX
- Branching for previews/agents
- pgvector without managing Postgres
Weaknesses
- Not a dedicated vector DB
- Cold starts on free compute
- Scale limits vs dedicated vector engines
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
