## What it is
Gryffin is a large-scale web security scanning platform written in Go, built on a publisher-subscriber architecture for horizontal scaling. It focuses on crawl coverage via page deduplication and DOM rendering, delegating actual fuzzing to external tools like sqlmap and arachni.

## Use cases
- scan thousands of web applications for security vulnerabilities at scale
- crawl javascript-heavy single page apps to discover links
- deduplicate template-driven pages during a security crawl
- integrate custom fuzzers like sqlmap into a scanning pipeline
- horizontally scale web vulnerability scanning infrastructure

## When to choose
- you need to scan a very large number of web apps with horizontal scaling
- you want a crawl/dedup platform to plug your own fuzzers into
- you need DOM rendering of client-side apps during crawling

## When to avoid
- you want a modern actively maintained scanner - the repo is archived since ~2021 and relies on deprecated PhantomJS
- you need a turnkey scanner with built-in vulnerability checks
- you want Windows-native or cloud-managed scanning without self-hosting
