## What it is
Spring Boot is an opinionated framework for building stand-alone, production-grade Spring-based Java applications with minimal configuration. It embeds servers like Tomcat or Jetty, provides starter dependencies, auto-configuration, and production-ready features such as metrics and health checks.

## Use cases
- build a rest api in java quickly
- create a stand-alone spring web application
- spin up microservices with embedded tomcat
- add health checks and metrics to a java service
- bootstrap a new spring project without xml configuration
- build production-grade backend services with minimal setup

## When to choose
- you want to build Spring applications with minimal configuration
- you need an embedded web server and runnable jar deployment
- you want opinionated defaults and starter dependencies to speed up development
- you need production-ready features like metrics, health checks, and externalized config out of the box

## When to avoid
- you need a lightweight non-Java stack or minimal runtime footprint
- your project is a simple script or CLI tool without web/service needs
- you prefer full manual control over Spring configuration and dependency choices

## Facets
- artifact type: framework
