Grails vs JHipster: What are the differences?

1. Language and Framework: Grails is based on the Groovy language and follows the convention-over-configuration paradigm, whereas JHipster is more focused on generating applications using Spring Boot for the backend and Angular/React/Vue for the frontend.
2. Architecture: Grails follows the Model-View-Controller (MVC) pattern for structuring applications, while JHipster promotes the use of microservices architecture with a focus on RESTful APIs.
3. Community and Ecosystem: Grails has a smaller but dedicated community with a strong focus on plugins and extensions, whereas JHipster has a large and active community with a significant emphasis on generating boilerplate code for faster development.
4. Code Generation: JHipster provides a powerful code generation tool that can scaffold CRUD operations, entities, and other functionalities, while Grails relies more on a plugin ecosystem for adding functionality to the framework.
5. Frontend Integration: JHipster seamlessly integrates with modern frontend frameworks like Angular, React, or Vue, providing options for single-page applications, whereas there is more flexibility in choosing frontend technologies in Grails with less integration out-of-the-box.
6. Deployment and Scalability: JHipster simplifies the deployment process with Docker and Kubernetes support, making it easier to scale applications, while Grails requires more manual configuration for deployment and scaling.

In Summary, Grails and JHipster differ in their languages, architectures, community support, code generation capabilities, frontend integration, and deployment options.
