Why FastAPI is Better Than Flask for Modern Web Apps
When it comes to building web applications with Python, Flask has long been a popular choice due to its simplicity and flexibility. However, in recent years, FastAPI has emerged as a strong alternative, particularly for building modern, high-performance web applications. In this blog post, we will compare FastAPI vs. Flask across various parameters to understand why FastAPI is the better choice for modern web apps . 1. Performance and Speed One of the most significant advantages of FastAPI over Flask is its speed. FastAPI is built on Starlette and Pydantic, utilizing asynchronous programming (async/await) to handle multiple requests efficiently. Benchmarks suggest that FastAPI is nearly as fast as Node.js and Go, making it an excellent choice for high-performance applications. Flask, on the other hand, is synchronous by default and does not natively support asynchronous programming. While you can integrate async features into Flask with additional extensions, it does not mat...
