Compare FastAPI and web2py
Fast API is a high-performance web framework for building web applications with Python 3.6+ based on standard Python type hints. It is designed to be high performance and easy to learn.
web2py was originally designed as a teaching tool, but it gained adoption outside of the academic world. It is a full-stack framework containing all the components needed to build fully functional web applications using the Model View Controller (MVC) pattern. Inspired by the Ruby on Rails and Django. It is not very popular right now but was ranked amongst top Python web frameworks in 2011.
Let's see how FastAPI and web2py compare on various factors and features and which to choose when.
Type
Minimalistic framework based on starlette and pydantic for building fast web applications using async IO.
Type
Python full-stack for building web applications.
New addition to the Python web frameworks family but its popularity is on the rise.
Used by
Uber (internal use,) Explosion AI, Microsoft (internal use)
Used by
Not in use at any large company.
100 job openings which list Fast API as a requirement.
8 job openings which list web2py as a requirement.
Web2py takes a unique approach where models and controllers are executed in a single global environment, which is initialized at each HTTP request. While there are pros to this approach, such as developers never having to worry about cleaning up or avoid conflict between requests, the major disadvantage is that the code is models is executed with every request which carries a performance penalty.
Flexibility
Fast API is flexible to code and doesn't restrict users to a particular project or code layout.
Flexibility
Not as flexible as microframeworks, but doesn't always get in the way.
Ease of Learning
Easy to learn especially for people who are new to web development. However, it doesn't have a large number of online resources, courses and tutorials.
Ease of Learning
Limited online tutorials and resources, and many are several years old. The best resource for learning is web2py author's own
"web2py Complete Reference Manual", which seems to be written in 2013.

How is performance rating determined?
Performance rating is determined using reputable online benchmarks listed below.
Where is job data coming from?
Job data is collected from Indeed, Google Jobs and Stack Overflow jobs.
How is popularity calculated?
Popularity is calculated using a formula which looks at weighted score on the following publicly available data points:
- Popularity per Google Trends
- Number of GitHub Users
- Number of GitHub Stars
How is this calculated?
Ease of learning is calculated using the following data:
- Number of features and depth of tool.
- Number of online resources: articles, blogs, tutorials and YouTube videos.
- Number of courses
- Freshness of online material
For example, a microframework may not have a lot of online resources but still get a high-rating because it's minamalistic and easy to learn just by following official documentation.
