## What it is
Mica is a Java toolkit and set of Spring Boot/Spring Cloud starter components for microservice development, offering utilities, captcha, HTTP client, Redis integration, IP geolocation, and XSS protection out of the box. It supports both traditional Servlet (web) and Reactive (WebFlux) stacks and tracks Spring Boot release versions.

## Use cases
- bootstrap a Spring Cloud microservice with common components preconfigured
- add captcha generation to a Spring Boot app
- simplify HTTP calls in Java microservices
- integrate Redis caching and distributed locks in Spring Cloud services
- protect endpoints from XSS attacks
- resolve IP addresses to geographic regions in a Java backend
- unify dependency versions across Spring Boot microservices with a BOM

## When to choose
- you build Spring Boot or Spring Cloud microservices in Java and want batteries-included starters
- you need both Servlet and WebFlux support in a shared component set
- you want drop-in utilities for captcha, Redis, HTTP, and XSS filtering without wiring them yourself

## When to avoid
- your stack is not JVM/Spring-based
- you prefer assembling individual libraries instead of an opinionated toolkit
- you need a framework with a large international community and English-first documentation
