The third position is held by Starlette, which FastAPI is built on. The big difference is the lack of warning from the Flask development server. Flask is used by many developers to host their APIs. req time = 815ms. req time = 125ms (Nginx log times includes time spent in uWSGI) I did the same test with my flask app and the result followed the same pattern. High-performance. Companies are also using business intelligence tools to predict future performance. For example, a throughput of 2.0 means "twice as fast as Flask+Gunicorn" and a throughput of 0.5 means "half as fast (or twice as slow) as Flask+Gunicorn". Conclusion: Flask 2.0 and FastAPI look very similar when doing a POST method. Flask used to be (and may be still is) the go-to HTTP server for python devs just starting out. Performance.

The objective was straightforward: to build a simple RESTful API that would allow a front end app to perform basic CRUD operations, providing me with an introduction to what the development process would look like. I've been shopping around for a back end framework to support a tabletop game app, and decided to do some research to determine the best fit for my needs.. Quart as a upgrade to Flask. Other functions provided by BI technologies include data mining, benchmarking, business performance management, and prescriptive analytics. Previous Rounds. Despite doing a bit of googling, there is not really a straight answer on this topic. Flask with the "flask run" server had a large number of non-2xx or 3xx responses, as expected of a development server. Whereas for Flask, the code processes the next request while the 10-second sleep is still happening. This makes FastAPI superior to Flask for larger-scale machine learning projects, especially enterprise ones, as it can handle requests much more efficiently. Source: TechEmpower Web Framework Benchmarks As you can see from the figure above, FastAPI is almost 3x faster than Flask. 1. Performance comparison of a wide spectrum of web application frameworks and platforms using community-contributed test implementations. .

The official documentation describes the following key features of FastAPI: Fast: very high performance, on par with NodeJS and Go. FastAPI, on the other hand, has a small user base due to its newness. There are common patterns for arranging flask apps and flask also offers blueprints as a way to make larger applications more modular and manageable. As you can see, for FastAPI, the code first waits 10 seconds before processing the next request.
