## What it is
crawlergo is a Go-based browser crawler that uses headless Chrome to discover URLs for web vulnerability scanners. It renders pages, fills and submits forms, triggers DOM events, and deduplicates URLs to produce high-quality crawl results.

## Use cases
- crawl a website to collect URLs for a vulnerability scanner
- discover hidden endpoints and links on a web app
- automatically fill and submit forms during crawling
- feed discovered URLs into a passive scanner
- fuzz common paths and parse JS files for links

## When to choose
- you need DOM-rendered, JavaScript-aware URL discovery
- you want automated form filling and event triggering during crawling
- you need a fast CLI crawler that integrates with vulnerability scanners

## When to avoid
- you need a general-purpose production web scraper for data extraction
- you cannot run a Chrome/Chromium environment
- you need authenticated crawling with complex session handling

## Facets
- artifact type: cli-tool
- maturity: active
- function: web-scraping, security, cli
- domain: security, crawlers, web-development, penetration-testing
- platform: windows, cli
- tags: headless-chrome, vulnerability-scanning, url-discovery, chromedp, form-filling, blackhat-arsenal, linux, macos, docker
