# Postgres clients for AI

> AI apps mostly fail at Postgres — connection pooling, prepared statements, vector indexes. There's a clean client to be built.

**Sector**: [Developer Tools](https://signals.gitdealflow.com/niche-down/developer-tools)  
**Build cost**: Month-long build  
**Deal velocity**: Steady — one deal per month

## Why now

Postgres is now the default AI database. The clients were built for traditional web apps and need redesign for vector workloads and serverless lifecycles.

## What the signal looks like

Repos with explicit pgvector + pgvectorscale support, edge runtime compatibility, and a benchmark README against node-postgres / postgres-js.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Neon serverless driver-style clients
- Drizzle ORM + pgvector adapters
- Pglite for in-browser Postgres clients

## What this displaces

node-postgres + a custom connection pool + manual pgvector queries.

## Our build-vs-invest call

Library now, hosted DB tomorrow. The library wedge gives you the integration list to launch your DB. Watch repos that ship Neon / Supabase / Xata adapters in their first six months.

## Frequently asked

### Is this a Vercel / Neon feature?

Partially. But the cross-vendor client (Neon + Supabase + RDS + self-hosted) is a third-party slot.

### Who's the user?

AI app developers using Next.js / Astro / SvelteKit / Remix.

### Does this expand?

Yes — client → hosted DB → vector search → eval store. Same path as Drizzle → DB → ORM.
