WSGI and ASGI Explained in simple terms

What is WSGI?

The Web Server Gateway Interface is abbreviated as WSGI. It’s a specification that explains how a web server connects with web apps and how web applications can be linked to perform a single request.

What is ASGI?

ASGI stands for Asynchronous Server Gateway Interface. it is a communication protocol for Python frameworks that provides async capabilities and enhances the capabilities of WSGI (Web Server Gateway Interface).
Starlette, FastAPI, and other frameworks that implement ASGI standards are popular.

What is the difference between WSGI and ASGI?


WSGI apps process a single request at a time and produce a response. WSGI’s lengthy connections, such as WebSocket connections, are limited by this single and synchronous callable.

Even if we made the application asynchronously callable, there is only one path for requests to be fulfilled.

As previously stated, ASGI is the successor to the highly successful WSGI. The purpose of ASGI is to maintain compatibility between web servers, frameworks, and applications such as WSGI in asynchronous Python.

ASGI web applications, unlike WSGI, can manage numerous requests due to their asynchronous nature.
