Nice concept, why flask though? Just for iteration speed? Because Python in almost 2026 is probably one of the worst choices for a web server, right after Javascript...
So quick iterations and rebuild once the SaaS has to scale I guess?

If you want to validate a product or run with a few K users (which I think this is helping), I really think that flask is a proven WS framework that just works.
The real question is not raw speed. It's how fast you ship, how many users you need before performance matters and whether you actually own your stack. Most modern solutions push you toward third party auth. This gives you full self hosted auth out of the box.
Scale problems are good problems to have.
One differentiator among others: try finding a stack with full self-hosted auth. Most push you toward third parties! I wanted to own my users.

If your app goes viral for some reason and has to scale within hours its not easy to rebuild for performance in that timeframe. Then if u use stuff like AWS and your app has a shit payment model that allows free tier users to just waste resources, good luck paying off that invoice.
