# Observability on Mastra platform

Observability on Mastra platform is a standalone hosted product for searchable traces, logs, and metrics across Mastra projects and deploys. Use it when you want observability without deploying Studio first or setting up local storage.

Mastra can configure platform observability during project setup. The CLI provisions a platform project, writes the required environment variables, and registers observability exporters in your Mastra config.

## Quickstart

Choose the setup path that matches your project. New and existing projects can use the CLI to provision Observability automatically, while manual setup is available when you already manage platform projects and environment variables yourself.

### New project

Create a new Mastra project:

**npm**:

```bash
npm create mastra@latest
```

**pnpm**:

```bash
pnpm create mastra
```

**Yarn**:

```bash
yarn create mastra
```

**Bun**:

```bash
bunx create-mastra
```

When prompted, enable Mastra Observability:

```bash
Enable Mastra Observability? (will open auth flow)

> Yes
```

The CLI authenticates with Mastra platform, creates a platform project, writes the required environment variables, and configures the observability exporters.

### Existing non-Mastra projects

If you already have an application, such as a Next.js app, but have not added Mastra yet, run `mastra init` and enable Mastra Observability when prompted:

**npm**:

```bash
npx mastra init
```

**pnpm**:

```bash
pnpm dlx mastra init
```

**Yarn**:

```bash
yarn dlx mastra init
```

**Bun**:

```bash
bun x mastra init
```

The CLI can select an existing platform project or create a new one.

### Manual setup

Create a project in [Mastra Platform](https://projects.mastra.ai), add `MASTRA_PLATFORM_ACCESS_TOKEN` and `MASTRA_PROJECT_ID` to `.env`, then register `MastraPlatformExporter` in your Mastra config. Add `MastraStorageExporter` if you also want to persist observability events to your configured Mastra Storage:

```ts
import { Mastra } from '@mastra/core/mastra'
import { Observability, MastraPlatformExporter } from '@mastra/observability'

export const mastra = new Mastra({
  observability: new Observability({
    configs: {
      default: {
        serviceName: 'mastra',
        exporters: [new MastraPlatformExporter()],
      },
    },
  }),
})
```

See [Mastra platform configuration](https://mastra.ai/docs/mastra-platform/configuration) for the environment variables used by platform observability.
