Making an app like this and putting it online (with roughly the same level of features) requires:
* Learning a backend language, like Python * Learning how to design a data model * Learning how to design an admin interface * Managing authentication, security, and performance * Learning HTML, CSS, and Javascript * Learning how to set up a uwsgi server * Learning how to set up an nginx server * Learning how to set up an AWS VM and deploy the above to it * Learning how to use a VCS
I'm an experienced programmer and sysadmin who has done all of those things and more over the last 20 years, and I still can't imagine going to the trouble of actually doing all of that if I can just log into HoneyComb and make everything nice and quick and just get it done.
There's value in learning how to do it, but there's also value in spending your time somewhere else. If you're making a simple CRUD app, bashing it together with Django and deploying it to an EC2 VM is almost definitely not your differentiated value proposition. If it's just a throwaway app to handle some mundane task, then it's definitely not wort hthe time it takes to make it if you don't have to.
