itty3

The itty-bitty Python web framework... Now Rewritten For Python 3!

If you're on Python 2, you're looking for itty for Python 2 instead...

Quick Start

import itty3

# Make an app (mostly just for routing & niceties).
app = itty3.App()

# Register your views with the app.
@app.get("/")
def index(request):
    return app.render(request, "Hello, world!")

if __name__ == "__main__":
    # Run a simple WSGI server!
    app.run()

Why?

itty3 is a micro-framework for serving web traffic. Prior to its inital release, itty3 weighed in at just 500 lines of code.

Granted, it builds on the shoulders of giants, using big chunks of the Python standard library. But it has no other external dependencies!

Reasons for itty3:

• Extremely lightweight
• Fast to start working with
• Easy to produce initial/toy services
• Minimal boilerplate
• Useful for places where you can't/don't have a full Python setup
• Useful for including directly, like when you lack permissions
• Works with a variety of WSGI servers, including Gunicorn

If you need to produce a big application, you're probably better off with Django, Flask, or any of the other larger/more mature web frameworks. No pressure!

Setup

pip install itty3 is what most people will want.

That said, itty3 is completely self-contained to a single file & relies only on the Python standard library. You can directly copy itty3.py into your project & import it directly!

Dependencies

• Python 3.7+
