Flask vs ASP.NET Core

Choosing the right backend framework is an important decision when building a modern web application. Flask and ASP.NET Core are both powerful technologies, but each one is designed for different project requirements.

Flask is a lightweight Python framework known for its simplicity, flexibility, and fast development process. It is commonly used for REST APIs, small to medium-sized web applications, prototypes, automation tools, and AI-powered projects. Since Flask provides only the essential features, developers have more control over the structure and components of their applications.

ASP.NET Core is a high-performance backend framework developed by Microsoft. It is widely used for enterprise applications, large-scale APIs, cloud-based systems, and secure business platforms. It provides built-in features such as dependency injection, authentication, routing, and structured project architecture, making it suitable for complex and scalable applications.

This blog compares Flask and ASP.NET Core based on performance, scalability, learning curve, development speed, security, and ideal use cases. It will help developers understand the strengths and limitations of both frameworks and choose the best option according to their project goals.
