## Ship Python to AWS in minutes, not days.

[**Documentation**](https://stelvio.dev/intro/quickstart/) - [**Stelvio Manifesto**](https://stelvio.dev/about/manifesto/) - [**Roadmap**](https://github.com/stelviodev/stelvio/wiki/Roadmap)

Stelvio is an **open-source** framework that lets you build and deploy modern AWS applications using **pure Python**. Forget YAML, complex configuration, or learning new DSLs.

With the `stlv` CLI, you focus on your code, and Stelvio handles the infrastructure.

## Why Stelvio?

- 🐍 **Pure Python**: Define your infrastructure with standard Python code. Use your favorite IDE, linter, and type checker.
- 🧠 **Smart Defaults**: We handle the complex IAM roles, networking, and configuration so you don't have to.
- 🔗 **Automatic Permissions**: Simply pass resources to your functions. Stelvio automatically configures permissions and environment variables.
- ⚡ **Live Dev Mode**: Run `stlv dev` to sync your code changes instantly. No waiting for deployments.
- 🔧 **Full Control**: Logic and infrastructure in one place, with escape hatches to the underlying Pulumi resources.
- 📖 **Open Source**: Built by developers for developers. Apache 2.0 licensed.

## Example

Define your infrastructure and application logic in one file. Stelvio handles the wiring.

```python
from stelvio.aws.api_gateway import Api
from stelvio.aws.cron import Cron
from stelvio.aws.dynamo_db import DynamoTable


@app.run
def run() -> None:

    todos = DynamoTable(
        "todos-table",
        fields={
            "user": "string",
            "date": "string"
        },
        sort_key="date",
        partition_key="user"
    )

    cleanup = Cron(
        "cleanup-cron",
        "rate(1 minute)",
        handler="api/handlers.cleanup",
        links=[todos]
    )

    api = Api("stlv-demo-api")
    api.route("GET", "/hello", handler="api/handlers.hello_world")
    api.route("POST", "/todos", handler="api/handlers.post_todo", links=[todos])
    api.route("GET", "/todos/{user}", handler="api/handlers.list_todos", links=[todos])
```
