Documentation - Stelvio Manifesto - 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.

• 🐍 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.

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

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])

Stelvio provides high-level components for the most common AWS services:

You can get up and running in less than 2 minutes.

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

# 2. Add Stelvio
uv add stelvio

# 3. Initialize project structure
uv run stlv init

# 4. Deploy to AWS
uv run stlv deploy

See the Quick Start Guide for a full walkthrough.

Stelvio is open source and we welcome contributions!
