code inside the framework Python file. It does not involve different
templates and CSS formatting for the front-end UI.
Flask very conveniently scales, can be customized to your liking and
is thoroughly tested. Additionally, there is a lot of support within the
community. On the downside, it can be overwhelming to begin with and
the user needs to have knowledge about frontend development as Flask
only provides backend support.
On the other hand for Streamlit, there is no reason to be concerned
with front-end development, it is easier to grasp and takes less time
between the development and deployment stage. But it has its own
drawbacks, there is no scaling, it is not yet fully developed and lacks
many features of Flask as it is in beta. Additionally, it does not have
the vast community and support ecosystem enjoyed by Flask.
For relatively simple apps Streamlit would suffice. But if the user
requires a more secure full-fledged app then Flask would be the better
If you want to learn more about the two frameworks, we recommend the following articles:
We already discussed the general case but we can always pack the
application into a container and further implement it with an
orchestration platform. What this does is, adds additional layers to the
pre-existing structure defined above.
