What is JHipster?

JHipster is a tool that helps you quickly build, develop, and launch contemporary web applications and microservice structures. It offers support for several front-end technologies like Angular, React, and Vue, as well as mobile app development using Ionic and React Native. On the backend, it offers compatibility with Spring Boot using Java or Kotlin, Micronaut, Quarkus, Node.js, and .NET. For deployment, JHipster follows cloud-native concepts and works with Docker and Kubernetes, and it can be deployed on various platforms such as AWS, Azure, Cloud Foundry, Google Cloud Platform, Heroku, and OpenShift.
