Flask vs Spring Boot: What are the differences?
Developers describe Flask as "a microframework for Python based on Werkzeug, Jinja 2 and good intentions". Flask is intended for getting started very quickly and was developed with best intentions in mind. On the other hand, Spring Boot is detailed as "Create Spring-powered, production-grade applications and services with absolute minimum fuss". Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
Flask can be classified as a tool in the "Microframeworks (Backend)" category, while Spring Boot is grouped under "Frameworks (Full Stack)".
"Lightweight", "Python" and "Minimal" are the key factors why developers consider Flask; whereas "Powerful and handy", "Easy setup" and "Java" are the primary reasons why Spring Boot is favored.
Flask and Spring Boot are both open source tools. Flask with 45.2K GitHub stars and 12.7K forks on GitHub appears to be more popular than Spring Boot with 39.8K GitHub stars and 25.8K GitHub forks.
According to the StackShare community, Flask has a broader approval, being mentioned in 511 company stacks & 531 developers stacks; compared to Spring Boot, which is listed in 333 company stacks and 615 developer stacks.
