What are the limitations of the flask built-in web server

Viewed 22516

I'm a newbie in web server administration. I've read multiple times that flask built-in web server is not designed for "production", and must be used only for tests and debug...

But what if my app touchs only a thousand users who occasionnaly send data to the server ?

If it works, when will I have to bother with the configuration of a more sophisticated web server ? (I am looking for approximative metrics).

In a nutshell, I would love to find what the builtin web server can do (with approx thresholds) and what it cannot.

Thanks a lot !

The OP has long-since moved on, but for those who encounter this question in the future I would just add that setting up an Apache server, even on a laptop, is free and pretty easy. It can be readily configured for as few or as many features as you want just by uncomment in or commenting out lines in the config file. There might be an even easier GUI method for doing that nowdays, but just editing the configs is simple.
