has a LAN HTTP function with low concurrency requirements. Less than 10 concurrency per second, the database is also sqlite,. I have tested that the concurrency of the run that comes with flask can reach more than 100. but the official hint is that it is prohibited to be used in the production environment. I have read other tutorials for flask deployment and found that there are a lot of things to install. Is there any run or libraries that can be easily deployed like the official?
