## What it is
JSFinder is a Python command-line tool that crawls a website's JavaScript files and extracts URLs and subdomains using regex parsing. It supports deep crawling, batch URL/JS input from files, custom cookies, and saving results to output files.

## Use cases
- extract urls and subdomains from a website's javascript files
- enumerate subdomains during bug bounty reconnaissance
- discover hidden api endpoints in js files
- crawl a site deeply to find more js links
- batch process a list of urls or js files for link extraction
- find attack surface of a web target

## When to choose
- you need a quick, lightweight way to pull endpoints and subdomains from JS during recon
- you want a simple Python script you can run with cookies or batch input files

## When to avoid
- you need a full-featured recon framework with active scanning or vulnerability checks
- you need maintained software with a license and recent updates
- you need browser-based or GUI analysis rather than CLI output

## Facets
- artifact type: cli-tool
