## What it is
WebCollector is an open-source Java web crawler framework that provides simple interfaces for building multi-threaded web crawlers quickly. It supports features like cookies, POST requests, proxies, and Selenium-based JavaScript rendering.

## Use cases
- crawl websites to collect pages
- build a multi-threaded web crawler in Java
- scrape news articles from the web
- crawl JavaScript-rendered pages with Selenium
- collect data for building a search index
- crawl sites through rotating proxies

## When to choose
- you need a quick-to-setup crawler on the JVM
- you want a lightweight Java alternative to Scrapy-style crawling
- you need multi-threaded crawling with proxy and cookie support

## When to avoid
- you need a distributed, large-scale crawling platform
- your stack is Python or Node.js rather than Java
- you need heavy-duty headless-browser automation beyond simple rendering

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-scraping, http-client, parser
- domain: crawlers, web-development
- platform: jvm, cross-platform
