## What it is
A Node.js library that manages a pool of Puppeteer-controlled Chromium instances for running browser tasks in parallel. It handles job queuing, error recovery, browser restarts, retries, and monitoring statistics across multiple concurrency models.

## Use cases
- crawl thousands of pages in parallel with headless chrome
- take screenshots of many urls concurrently
- run browser-based tests in parallel
- scrape websites with automatic retry on failure
- pool and reuse chromium browser instances
- monitor progress of a batch of puppeteer jobs

## When to choose
- you need to run many puppeteer tasks concurrently with error handling and retries
- you want automatic browser restart after crashes
- you need progress monitoring and statistics for crawling jobs

## When to avoid
- you only need a single browser instance for one-off automation
- you need distributed scraping across multiple machines
- your scraping does not require a full browser and can use plain HTTP requests

## Facets
- artifact type: library
- maturity: stable
- function: web-scraping, concurrency, http-client
- domain: web-development, crawlers, developer-tools
- platform: cross-platform
- tags: puppeteer, headless-chrome, browser-pool, parallel-crawling, screenshot, job-queue, automation, nodejs
