## What it is
Arachni is a modular, high-performance Ruby framework for scanning web applications for security vulnerabilities, including XSS and SQL injection, with an integrated browser environment for auditing JavaScript/DOM-heavy apps. The project is now obsolete and has been replaced by its successor, Spectre Scan by Ecsypno.

## Use cases
- scan a web application for vulnerabilities
- find XSS and SQL injection flaws in my site
- audit JavaScript-heavy web apps for security issues
- crawl a website and detect security weaknesses
- run a penetration test on a web app from the command line

## When to choose
- you need a self-contained Ruby-based web vulnerability scanner for legacy environments
- you want DOM/JavaScript-aware auditing with false-positive reduction

## When to avoid
- you need actively maintained tooling - the project is officially obsolete
- you want a modern scanner - use its successor Spectre Scan or alternatives like OWASP ZAP instead
- you require a permissive open-source license - it uses a custom Arachni Public Source License

## Facets
