## What it is
crAPI (completely ridiculous API) is an intentionally vulnerable web application built by OWASP to demonstrate the OWASP API Security Top 10 risks. It is a microservices-based application designed to be safely self-hosted for security training and practice.

## Use cases
- learn the OWASP API Security Top 10 hands-on
- practice API penetration testing against a safe target
- train security teams on API vulnerabilities
- test API security scanning tools
- set up a deliberately vulnerable lab environment with docker compose
- demonstrate API security risks in workshops

## When to choose
- you need a realistic, intentionally vulnerable API for security training or CTF-style challenges
- you want to evaluate API security tooling against known vulnerabilities
- you're teaching or learning API security concepts

## When to avoid
- you need a production-ready API framework or boilerplate
- you want a secure reference implementation to copy into your own project
- you can't run Docker or don't want to host a vulnerable service

## Facets
- artifact type: application
- maturity: active
