Guide for using Netlify DB (managed Neon Postgres). Use when the project needs a relational database, structured data storage, SQL queries, or data that will grow over time. Covers provisioning, raw SQL via @netlify/neon, Drizzle ORM integration, migrations, and deploy preview branching. Also covers when to use Netlify Blobs instead.

Netlify DB provisions a managed Neon Postgres database automatically. No Neon account required.
Use Netlify DB when:
Use Netlify Blobs instead when:
@netlify/blobsSee the netlify-blobs skill for Blobs usage.
npm install @netlify/neon
netlify db init # Provisions database and sets up Drizzle ORM
Prerequisites: logged into Netlify CLI and site linked (netlify link).
@netlify/neon wraps @neondatabase/serverless. No connection string needed — it auto-configures.
import { neon } from "@netlify/neon";
const sql = neon();
const users = await sql("SELECT * FROM users");
await sql("INSERT INTO users (name) VALUES ($1)", ["Jane"]);
await sql("UPDATE users SET name = $1 WHERE id = $2", ["Jane", 1]);
await sql("DELETE FROM users WHERE id = $1", [1]);
For most projects, use Drizzle ORM on top of Netlify DB.
import { defineConfig } from "drizzle-kit";
export default defineConfig({
dialect: "postgresql",
dbCredentials: { url: process.env.NETLIFY_DATABASE_URL! },
schema: "./db/schema.ts",
out: "./migrations",
migrations: { prefix: "timestamp" }, // Avoids conflicts across branches
});
import { neon } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import * as schema from "./schema";
const sql = neon(process.env.NETLIFY_DATABASE_URL!);
export const db = drizzle(sql, { schema });
export * from "./schema";
// db/schema.ts
import { integer, pgTable, varchar, text, boolean, timestamp } from "drizzle-orm/pg-core";
export const items = pgTable("items", {
id: integer().primaryKey().generatedAlwaysAsIdentity(),
title: varchar({ length: 255 }).notNull(),
description: text(),
isActive: boolean("is_active").notNull().default(true),
createdAt: timestamp("created_at").defaultNow(),
updatedAt: timestamp("updated_at").defaultNow(),
});
export type Item = typeof items.$inferSelect;
export type NewItem = typeof items.$inferInsert;
import { db, items } from "../db";
import { eq } from "drizzle-orm";
const all = await db.select().from(items);
const [one] = await db.select().from(items).where(eq(items.id, id)).limit(1);
const [created] = await db.insert(items).values({ title: "New" }).returning();
const [updated] = await db.update(items).set({ title: "Updated" }).where(eq(items.id, id)).returning();
await db.delete(items).where(eq(items.id, id));

"db:generate": "drizzle-kit generate",
"db:migrate": "netlify dev:exec drizzle-kit migrate",
"db:push": "netlify dev:exec drizzle-kit push",

}
}
Workflow: modify schema, run db:generate, then db:migrate.
Netlify DB supports branching — production branch gets the production database, all other branches and deploy previews get a separate preview branch. Develop and test migrations on preview, merge to main, then apply to production.
NETLIFY_DATABASE_URL — Auto-set by Netlify when database is provisionednetlify env:get NETLIFY_DATABASE_URLRun netlify dev or use @netlify/vite-plugin to get database access locally. Use netlify dev:exec to run migration commands with the proper environment.

Guide for using Netlify Image CDN for image optimization and transformation. Use when serving optimized images, creating responsive image markup, setting up user-uploaded image pipelines, or configuring image transformations. Covers the /.netlify/images endpoint, query parameters, remote image allowlisting, clean URL rewrites, and composing uploads with Functions + Blobs.
tools
Deploy web projects to Netlify using the Netlify CLI (`npx netlify`). Use when the user asks to deploy, host, publish, or link a site/repo on Netlify, including preview and production deploys.

Reference for Netlify AI Gateway — the managed proxy that routes calls to OpenAI, Anthropic, and Google Gemini SDKs without provider API keys. Use this skill any time the user wants to add AI on a Netlify site (chat, completion, reasoning, image generation, image-to-image edit/stylize), choose or change a model, wire up the OpenAI / Anthropic / @google/genai SDK, decide which provider to use for an image-gen feature (it's Gemini-only on the gateway), or debug "model not found" / "API key missing" against the gateway. Required reading before pinning a model — the gateway exposes a curated subset, not every provider model.
