I found a old 2014's post already related to this question, it seems that there is no 2017 answer for this one, could anyone tell me if it changed? I mean, even if the default configuration is not safe, is there a way to suit flask to be production prove?
(old link: Is the server bundled with Flask safe to use in production?)
I would like to use it, if it scales well and it is safe, I am planning to create something useful. I like this basic easy concept very well, I hope it could be suitable in 2017.
Flask and other Werkzeug servers shouldn't be ran directly. The number one post for the question that you linked to still notes in their documentation that it is not safe directly for development.
I use gunicorn for production, it's very easy to use.
