## What it is
Zed Attack Proxy (ZAP) by Checkmarx is a free, open-source web application security scanner used for finding vulnerabilities in web apps during development and manual penetration testing. It supports automated scanning via Docker, GitHub Actions, an automation framework, and a comprehensive API/daemon mode, plus a desktop GUI.

## Use cases
- scan my web application for security vulnerabilities
- run automated DAST scans in CI/CD pipeline
- perform manual penetration testing on a web app
- find OWASP Top 10 issues in my website
- proxy and inspect HTTP traffic from my browser
- automate security scanning of a web API
- quick reconnaissance scan of a URL

## When to choose
- you need a free, open-source DAST scanner for web apps or APIs
- you want both automated CI/CD scanning and manual pentesting tools in one tool
- you need a Burp Suite alternative without commercial licensing
- you want extensive extensibility via community add-ons and a full API

## When to avoid
- you need static source code analysis (SAST) rather than runtime scanning
- you need to scan non-HTTP protocols or thick desktop/mobile binaries
- you want a zero-configuration commercial product with vendor support guarantees
