Disadvantages of flask

Some of the major disadvantages of the flask framework are,

1. Not suitable for big applications.
2. Community.
3. Full-Stack experience.
4. No admin site.
5. No login or authentication.
6. ORM.
7. Migrations can be difficult.

These disadvantages are based on comparing flask with Django. Django is heavy-weight, whereas, with Flask, you have to build everything on your own.

Not suitable for big applications

when you have a big project, using Flask could be time-consuming. It is suitable only for small-scale applications. If you have a simple, innovative use case to be added to an existing application, Flask should be your choice as it offers flexibility.
