AWS for Python devs - made simple

Documentation - Stelvio Manifesto - Intro article with quickstart

What is Stelvio?

Stelvio is a Python framework that simplifies AWS cloud infrastructure management and deployment. It lets you define your cloud infrastructure using pure Python, with smart defaults that handle complex configuration automatically.

With the stlv CLI, you can deploy AWS infrastructure in seconds without complex setup or configuration.

Key Features

• Developer-First: Built specifically for Python developers, not infrastructure experts
• Zero-Setup CLI: Just run stlv init and start deploying - no complex configuration
• Python-Native Infrastructure: Define your cloud resources using familiar Python code
• Environments: Personal and shared environments with automatic resource isolation
• Smart Defaults: Automatic configuration of IAM roles, networking, and security

Currently Supported

• AWS Lambda & Layers
• Amazon DynamoDB
• API Gateway
• Linking - automated IAM
• S3 Buckets
• Custom Domains

Support for additional AWS services is coming. See Roadmap.

Example

Define AWS infrastructure in pure Python:

@app.run
def run() -> None:
    # Create a DynamoDB table
    table = DynamoTable(
        name="todos",
        partition_key="username",
        sort_key="created"
    )
    
    # Create an API with Lambda functions
    api = Api("todos-api", domain_name="api.example.com")
    api.route("POST", "/todos", handler="functions/todos.post", links=[table])
    api.route("GET", "/todos/{username}", handler="functions/todos.get")

See the intro article for a complete working example.

Quick Start

# Create a new project
uv init my-todo-api && cd my-todo-api

# Install Stelvio
uv add stelvio

# Initialize Stelvio project
uv run stlv init

# Edit stlv_app.py file to define your infra

# Deploy
uv run stlv deploy

Go to our Quick Start Guide for the full tutorial.

Why Stelvio?

Unlike generic infrastructure tools like Terraform, AWS CDK or Pulumi Stelvio is:

• Built specifically for Python developers
• Focused on developer productivity, not infrastructure complexity
• Designed to minimize boilerplate through intelligent defaults
• Maintained in pure Python without mixing application and infrastructure code

For detailed explanation see Stelvio Manifesto blog post.
