## What it is
Apache Grails is a Groovy-based web application framework for the JVM, built on top of Spring Boot, using convention-over-configuration to speed up development. It integrates with GORM for data access across SQL and NoSQL stores and supports building REST APIs or web apps with React/Angular profiles.

## Use cases
- build a web application in groovy on the jvm
- create a rest api with spring boot and groovy
- rapidly scaffold a crud web app with convention over configuration
- build a backend with hibernate or mongodb via gorm
- develop a full-stack app with react or angular frontend
- migrate a java spring boot app to a more productive framework

## When to choose
- your team knows Java/Groovy and wants a productive, opinionated full-stack framework on the JVM
- you want Spring Boot power with less boilerplate via convention-over-configuration
- you need GORM's unified data access across Hibernate, MongoDB, Cassandra, or Neo4j
- you want built-in scaffolding, testing, and a large plugin ecosystem

## When to avoid
- you need a lightweight microservice-only toolkit without a full-stack framework
- your team prefers non-JVM stacks or frameworks like Rails/Django equivalents in other languages
- you want maximum control over project structure rather than conventions
- you require bleeding-edge reactive or GraalVM native-image-first development
