## What it is
Firing Range is a deliberately vulnerable Java web application that serves as a test bed for web application security scanners. It provides synthetic, wide coverage of an array of vulnerabilities and can be deployed on Google App Engine or run locally.

## Use cases
- test a web application security scanner against known vulnerabilities
- benchmark coverage of a DAST scanner
- validate that a vulnerability scanner detects XSS and injection flaws
- set up a local vulnerable target for security tooling development
- compare effectiveness of different web security scanners
- provide a safe synthetic target instead of testing on real apps

## When to choose
- you need a broad, synthetic set of web vulnerabilities to evaluate or tune a security scanner
- you want a self-hosted or App Engine-deployable test target for DAST tooling
- you are developing web vulnerability detection logic and need reproducible test cases

## When to avoid
- you need a real-world vulnerable application rather than synthetic test cases
- you want a security training platform with guided lessons rather than a raw test bed
- you need a non-Java or non-App Engine deployment target without adaptation

## Facets
- artifact type: application
- maturity: maintenance
- function: security, testing, http-server
- domain: security, testing, web-development
- platform: jvm, cloud, self-hosted
- tags: vulnerable-app, scanner-testbed, app-engine, synthetic-vulnerabilities, penetration-testing-target, web-server
