Welcome to Stelvio

Stelvio is a Python library that makes AWS development simple for for Python devs.

It lets you build and deploy AWS applications using pure Python code, without dealing with complex infrastructure tools.

Head over to the Quick Start guide to get started.

Stelvio is in Early alpha state - Not production ready - Only for experimentation - API unstable

Stelvio is currently in active development as a side project.

It supports basic Lambda, Dynamo DB and API Gateway setup.

Why I Built This

As a Python developer working with AWS, I got tired of:

  • Switching between YAML, JSON, and other config formats
  • Figuring out IAM roles and permissions
  • Managing infrastructure separately from my code
  • Clicking through endless AWS console screens
  • Writing and maintaining complex infrastructure code

I wanted to focus on building applications, not fighting with infrastructure. That's why I created Stelvio.

How It Works

Here's how simple it can be to create an API (Gateway) with Stelvio:

from stelvio import Api

api = Api('my-api')
api.route('GET', '/users', 'users/handler.index')
api.route('POST', '/users', 'users/handler.create')
api.deploy()

Stelvio takes care of everything else:

  • Creates Lambda functions
  • Sets up API Gateway
  • Handles IAM roles and permissions
  • Makes sure your resources can talk to each other
  • Deploys everything properly

What Makes It Different

Just Python

Write everything in Python. No new tools or languages to learn. If you know Python, you know how to use Stelvio.

Smart Defaults That Make Sense

Start simple with sensible defaults. Add configuration only when you need it. Simple things stay simple, but you still have full control when you need it.

Type Safety That Actually Helps

Get IDE support and type checking for all your AWS resources. No more guessing about environment variables or resource configurations.

Works Your Way

Keep your infrastructure code wherever makes sense:

  • Next to your application code
  • In a separate folder
  • Or mix both approaches

What I Believe In

I built Stelvio believing that:

  1. Infrastructure should feel natural in your Python code
  2. You shouldn't need to become an AWS expert
  3. Simple things should be simple
  4. Your IDE should help you catch problems early
  5. Good defaults beat endless options
