## What it is
Hero is a headless web browser built specifically for web scraping, powered by Chrome and controlled from NodeJS with a fully compliant DOM API. It includes browser emulation and full-stack anti-detection features to avoid being blocked by fingerprinting.

## Use cases
- scrape websites that block headless browsers
- extract data from javascript-heavy pages
- automate browser interactions without puppeteer evaluate callbacks
- emulate different browser fingerprints to avoid detection
- bypass TLS fingerprint blocking
- parse and query page DOM directly from nodejs

## When to avoid
- you only need simple static HTML fetching
- you are doing automated UI testing rather than scraping
- you need a browser in a non-NodeJS language

## Facets
- artifact type: library
- maturity: active
- function: web-scraping, http-client, browser-extension
- domain: crawlers, web-development
- platform: cross-platform
