If your asking this question the answer is Django. There’s nothing else left that’s really being actively developed in the open source space and nobody wants to admit it.
Django/Flask will have 100x as many resources to help you than FastAPI will, given the nature of your question that's what your decision should be based on.
If you are interested in something outside of Python then Ruby on Rails also has resources in depth.
This is an unlabeled advertisement for substack. Please stop the endless substack spamming. They just lie about the earnings they all have relationships with substack, stop fucking commuting fraud by allowing all these fake “I’m just a random influencer and I love substack” posts, it’s illegal to not disclose that they are paid to say this.
How do you know it’s a paid ad by Substack? I’m perfectly willing to believe that, but the simpler explanation seems to be that it’s an ad for the author’s book.
After your comment, I went and read the article too. Scroll down to the below part onwards

I honestly doubt someone who just met the founders of a company face to face would then write an article purely void of any need to promote the platform, plus when you look at the text following what I quoted, I doubt that would be written without checking with the company first.
