## What it is
simplecrawler is a flexible, event-driven web crawler library for Node.js with a configurable queue system, robots.txt support, and link discovery. It is explicitly unmaintained, so users are advised to migrate to alternatives.

## Use cases
- crawl an entire website and archive its pages
- scrape all links from a site
- build a site search index by crawling pages
- download large websites to disk
- monitor website pages for changes
- extract resources from a domain respecting robots.txt

## When to choose
- you need a low-level, highly configurable crawler base in Node.js
- you want event-driven control over fetching and link discovery
- you need a queue that can be frozen to disk and resumed

## When to avoid
- you need a maintained library with active support
- you want a modern headless-browser-based crawler for JavaScript-rendered sites
- you are starting a new project (the README recommends migrating to alternatives)
