Flask is one of the most popular frameworks in Python to develop web applications, but when it comes to moving to production, you need a server like Gunicorn to deploy it.HTTP Server Features: Flask does not include built-in support for handling HTTP server features like HTTP/2, keep-alive connections, and websocket support. In contrast, Gunicorn provides these features out of the box, making it a more suitable choice for applications that require advanced HTTP functionality.Flask: Provides excellent performance and scalability for small to medium-sized applications. With its minimalist design, Flask allows developers to optimize performance by selecting only the necessary components and dependencies.
What server to use with Flask : Although Flask has a built-in web server, as we all know, it's not suitable for production and needs to be put behind a real web server able to communicate with Flask through a WSGI protocol. A common choice for that is Gunicorn—a Python WSGI HTTP server. Serving static files and proxying request with Nginx.
Do any big companies use Flask
Pinterest and Twilio leverage Flask for rapid prototyping and API development. Uber and Mozilla have reportedly integrated Flask for specific services within their tech stacks. These companies harness Flask's simplicity and flexibility for various backend tasks and web services.
Is Flask used professionally : Flask is used by developers worldwide to build web applications, RESTful APIs, and microservices. Its simple and modular structure makes it an easy framework to learn for beginners, compared to other full-stack frameworks like Django.
According to the 2022 JetBrains Python Developers Survey, Django and Flask are by far the two most popular Python web frameworks.
FastAPI generally outperforms Flask, especially in applications that benefit from asynchronous I/O operations. FastAPI's design allows it to handle more requests per second than Flask, making it a better choice for high-load applications.

Can FastAPI be used in production
FastAPI is built with modern Python features such as asynchronous programming with an event loop, utilizes Pydantic for data validation and generates standard OpenAPI specs from the Python metadata which allows you to build a well documented production grade API very quickly.
Flask is an excellent choice for projects where ease of use, customizability, and a rich set of resources are crucial. FastAPI, on the other hand, is ideal for those seeking a modern, high-performance framework for complex, high-concurrency applications.Big industry players like Netflix and Reddit incorporate Flask in their backend infrastructure. Lyft and LinkedIn also utilize Flask for specific functionalities within their systems. Pinterest and Twilio leverage Flask for rapid prototyping and API development.
Does Netflix use FastAPI : Netflix is a widely popular subscription-based streaming service that is using FastAPI, offering a vast library of movies, TV shows, documentaries, and original content to its subscribers.
