# Development server

> Run a schema locally with the playground and schema endpoints.

The bundled async HTTP server is a dependency-free development convenience.

```bash theme={null}
python -m fastql serve examples.app:schema
```

By default it listens on `http://127.0.0.1:7691` and exposes:

| Route             | Purpose                              |
| ----------------- | ------------------------------------ |
| `/`               | Interactive GraphQL playground       |
| `/graphql`        | GET and POST GraphQL execution       |
| `/schema.graphql` | Generated schema definition language |
| `/schema.json`    | Introspection result as JSON         |

The GraphQL POST body accepts `query`, `variables`, and `operationName`. A GET
request accepts equivalent query-string parameters.

<Warning>
  The development server has no TLS, authentication, keep-alive, chunked transfer,
  or production hardening. Put FastQL execution behind an application framework or
  transport designed for production use.
