# Refer a friend and earn credits, Neon backend private preview, and more

## Refer a friend and earn credits

We're piloting a referral program. Send a friend your referral link, and when they sign up for Neon and spend $5, you get $5 in credits.

This is an early pilot, so we're still shaping it. Tell us what would make a referral program most useful to you, whether that's different rewards, how you share your link, or something else, in our [Discord feedback channel](https://discord.com/channels/1176467419317940276/1176788564890112042).

## Neon backend for apps and agents now in private preview

Neon Storage, Functions, and AI Gateway are now in private preview.

- **Functions**: long-running Node.js compute next to your database. WebSocket servers, SSE streams, AI agents.
- **Storage**: S3-compatible object storage that branches with your data.
- **AI Gateway**: one credential for frontier and open-source models (Claude, GPT, Gemini, and more).

Sign up below and we'll send you the **private preview guide** to get started.

## Introducing neon.ts: infrastructure as code for your Neon project

`neon.ts` is a TypeScript config file you commit to your repo. Use it as branch policy infrastructure as code (for example, TTL, compute sizing, and scale-to-zero settings), and to declare which Neon services your project uses:

```ts
import { defineConfig } from "@neondatabase/config/v1";

export default defineConfig({
  auth: true,
  dataApi: true,
  branch: (branch) => {
    if (!branch.exists) {
      return {
        ttl: "7d",
        postgres: {
          computeSettings: {
            autoscalingLimitMinCu: 0.25,
            autoscalingLimitMaxCu: 1,
            suspendTimeout: "5m",
          },
        },
      };
    }
    return {};
  },
  preview: {
    functions: { /* ... */ },
    buckets: { /* ... */ },
    aiGateway: true,
  },
});
```

Apply it with `neonctl deploy`, preview changes first with `neonctl config plan`. The `@neondatabase/env` package gives you type-safe access to the environment variables each declared service injects, so missing or misconfigured variables surface at build time rather than runtime.

If you've signed up for the **Neon backend for apps and agents private preview**, the `preview` block enables Functions, Storage buckets, and AI Gateway in the same config. Fork a branch and you get an isolated copy of your database, files, storage, functions, and AI gateway.

See the [neon.ts reference](https://neon.com/docs/reference/neon-ts) for the full config schema, or read the [blog post](https://neon.com/blog/introducing-neon-ts) for a full walkthrough.

## Export Neon metrics to SigNoz

This new guide shows how to export your Postgres logs and metrics to [SigNoz](https://signoz.io) using the Neon OpenTelemetry integration. Once set up, your database telemetry lands alongside your application data in SigNoz, making it easier to spot and investigate performance issues across your stack.

## Fixes & improvements

<details>

<summary>**Neon API**</summary>

The deprecated `GET /consumption_history/account` endpoint has been removed. Use `GET /consumption_history/v2/projects` instead. See [Querying consumption metrics](https://neon.com/docs/guides/consumption-metrics) for details.

<details>

<summary>**Vercel integration**</summary>

For [Neon-Managed (Connectable Account) Vercel integrations](https://neon.com/docs/guides/neon-managed-vercel-integration), rotating the selected Postgres role password in Neon now automatically syncs updated credentials to Vercel environment variables. This removes the need to manually re-save integration settings after password rotation.
