ASGI vs CGI

Developers should learn and use ASGI when building high-performance, real-time web applications in Python that require asynchronous capabilities, such as chat apps, live notifications, or APIs with WebSocket support meets developers should learn cgi to understand the historical evolution of web technologies and for legacy system maintenance, as some older applications still rely on it. Here's our take.

ASGI

Nice Pick

Developers should learn and use ASGI when building high-performance, real-time web applications in Python that require asynchronous capabilities, such as chat apps, live notifications, or APIs with WebSocket support

Pros

• It is essential for modern Python web frameworks like FastAPI, Starlette, and Django Channels, allowing them to leverage async/await syntax for efficient handling of concurrent requests and long-lived connections
• Related to: python, fastapi

Cons

• Specific tradeoffs depend on your use case

CGI

Developers should learn CGI to understand the historical evolution of web technologies and for legacy system maintenance, as some older applications still rely on it

Pros

• It's also useful for educational purposes to grasp how server-side processing works at a low level, such as in simple scripting tasks or embedded systems where lightweight solutions are needed
• Related to: http-protocol, server-side-scripting

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. ASGI is a framework while CGI is a concept. We picked ASGI based on overall popularity, but your choice depends on what you're building.

The Bottom Line

ASGI wins

Based on overall popularity. ASGI is more widely used, but CGI excels in its own space.
