# Files that branch with your Neon database

Neon Object Storage

**Diagram:** Creating a Neon preview branch forks the Postgres database and its S3-compatible object storage together, including tables, data, files, and assets.

## Get started

- [Start building](https://console.neon.tech/signup)
- [Read the docs](https://neon.com/docs/storage/overview)

## In one step, branch both your database and your files.

Your buckets come with your Postgres data into isolated environments, without duplicating storage.

### S3 compatible: Keep your stack

boto3, the AWS SDK, and the CLI work with Neon Object Storage out of the box. Swap the endpoint and keep your existing code.

### One credential: No separate cloud account

Authenticate with a Neon credential instead of a separate AWS account and IAM setup.

### Branchable storage: Buckets that branch with your database.

No files are duplicated up front (it's copy-on-write). The bill only grows if the branch diverges.

## Test on real environments.

On Neon, a branch forks Postgres and your files together, with nothing duplicated upfront.

### Isolated by default

Uploads and deletes on a preview or PR branch never touch production or any sibling branch.

### Copy-on-write

Creating a branch doesn’t copy your objects. You pay for what diverges, not for a second bucket.

### Disposable

Delete the branch and its files go with it. Same workflow for a human, a CI job, or an agent.

## Ask your agent: deploy Postgres and files via the Neon backend

### neon.ts

```typescript
import { defineConfig } from "@neon/config/v1";

export default defineConfig({
  preview: {
    aiGateway: true,
    buckets: {
      uploads: {},
    },
  },
});
```

### One config

Define your bucket alongside Postgres and keep your database and files together in the same `neon.ts` configuration.

### One deploy

Run `neon deploy` to provision the bucket and automatically pull the required S3 variables into your `.env.local`.

### Agent tools

Agents are a first-class interface through Neon’s API, CLI, and MCP server.

## Your questions, answered

### What is Neon Object Storage?

S3-compatible blob storage for your files, built into the Neon backend. This is different from the object store Lakebase Postgres uses internally for database pages. You upload objects into buckets, point a standard S3 client at your branch endpoint, and authenticate with a Neon credential.

### What happens to my files when I branch?

The child branch inherits your buckets and objects with your database. Each branch has its own isolated storage namespace, so uploads and deletes on one branch do not affect its parent or siblings.

### Do I pay for a full copy of my files on every branch?

No. Branching uses copy-on-write, so creating a branch does not duplicate your objects upfront. Storage grows as the branch diverges.

### Do I need an AWS account?

No. Use your Neon storage credential and branch endpoint with an S3-compatible client. There is no separate AWS account or IAM setup to manage.

### How do I add a bucket to a project?

Declare a bucket under `preview.buckets` in `neon.ts`, then run `neon deploy` to provision it and pull the S3 variables into `.env.local`. You can also create buckets from the Neon Console, CLI, Neon API, or S3 API.

### Is this the same credential I use for Postgres?

Object Storage uses Neon’s scoped-credential system, shared with AI Gateway, with storage read and write scopes. Your S3 client uses the credential’s Access Key ID and Secret Access Key. Postgres connections use your database role and connection string.

## Backend services

Your files branch with everything else. Create a branch and your whole backend forks with it — database, storage, auth, and a gateway endpoint of its own.

### Lakebase Postgres

Serverless Postgres that scales and branches with your app.

### Authentication

Managed auth with users and sessions stored in Postgres.

### Compute

Functions without timeouts running close to your database.

### Storage

S3-compatible object storage that branches with your projects.

### AI Gateway

One API for all frontier & open-source models, powered by Databricks.

## Built for agents and the developers behind them.

Every service is designed with the same API and operational model, whether it's used by a developer or called directly by an AI agent. Build once, then let both humans and agents use the same platform without additional integration work.

### Branchable

Spin up isolated environments to test model changes safely, without touching production. Merge changes only when they're ready.

### Serverless

Usage-based infrastructure that scales automatically with your traffic, so you only pay for what you use and nothing while idle.

### Agent-ready

Provision and operate every service through APIs that AI agents can call directly, using the same interfaces as developers.
