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?

Not OP but I think it's a bit harsh on flask tbh.

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.

Python is having a moment right now, between the AI ecosystem, Astral tooling and a huge talent pool. I think calling it the worst choice is a stretch :)

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.

There are many node/js alternatives, nice to have one for the Python devs

		Agreed! 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. https://medium.com/@level09/the-stack-that-owns-you-7ff06b26...

For 99% of the SaaS teams, low latency becomes an issue later unless the product itself needs to be catering with that feature. Focus with kits like this is to get everything running on day 0.

Its not about low latency but memory consumption too. If you have unlimited money to throw at Fly.io or AWS its no issue sure, but other than that you might wanna be mindful with the resources you waste due to using the wrong tool for the problem.

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.

		There's no reason to throw money at those providers when there are many options a dozen times cheaper.

		Also it's not fun to play catch-up due to performance issues, because popularity will trigger competition from other corporations and they are unlikely to pick dynamic languages with reputation issues regarding things like latency.
