Stario: Bringing Back the Joy of Web Development

Stario is a lightweight Python web framework built for the modern era of real-time collaborative web apps. Building on the simplicity of Datastar, Stario lets you build reactive, multiplayer web applications without the complexity of modern JavaScript silos. Keep application state where it belongs: on the server, and focus on things that actually matter.

Get Started Instantly

The fastest way to build your first Stario app is using uv:

# Initialize a new Stario project based on one of the templates
uvx stario@latest init

Note: Stario v2 requires Python 3.14+ (v1 supported >=3.12). Always use stario@latest to ensure you get the current version - without it, uvx may use a cached older release.

Alternatively, install it via your favorite package manager:

# Using uv
uv add stario

# Using pip
pip install stario
