## What it is
Lightcrawler is a Node.js CLI tool that crawls a website by following links and runs each discovered page through Google Lighthouse audits. It is configured via a JSON file controlling crawl depth, Chrome instances, and which Lighthouse categories or audits to run.

## Use cases
- audit every page of a website with lighthouse
- crawl a site and check accessibility across all pages
- run performance audits on multiple pages automatically
- find lighthouse violations site-wide instead of page by page
- batch-run lighthouse audits in ci

## When to choose
- you need lighthouse results for many pages of a site, not just one
- you want a simple -configured crawler around lighthouse
- you are auditing accessibility or performance across a whole site

## When to avoid
- you only need to audit a single url (use lighthouse directly)
- you need actively maintained tooling (project has seen little activity since 2022)
- you need crawling features like authentication or javascript-driven discovery beyond lighthouse's chrome instance
