Things people build with this

USE CASE 1

Build real-time APIs that handle thousands of simultaneous user requests without slowing down.

USE CASE 2

Create microservices that process requests concurrently while waiting for database or external API responses.

USE CASE 3

Deploy high-traffic web applications that need to scale efficiently with minimal server resources.

In plain English

Sanic is a Python web framework designed for building fast HTTP servers. It requires Python 3.10 or later and is built around Python's async/await syntax, which allows the server to handle many requests at the same time without blocking, meaning while one request is waiting for a database response, the server can be processing other requests. This makes it well-suited for applications that need to handle high volumes of traffic or many simultaneous connections. Sanic also supports ASGI, a standard interface that lets it run behind alternative web servers beyond its built-in one. It is available as a package installable via pip. The framework's design goal is to be easy to start with but capable of scaling. The project is community-maintained and welcomes contributions. A web interface and community forum are available for support.
