PHP XML Sitemap Generator

A PHP library and command line script by iProDev that builds a sitemap by crawling a given URL. Version 3.0 adds database storage with change detection and historical tracking, a resume capability with a checkpoint system, proxy support with rotation, webhook notifications for events and scheduled crawling through cron. A caching layer works with files or Redis, and smart filtering keeps unwanted URLs out. Beyond standard sitemaps it supports several sitemap types and multiple output formats. A content quality checker finds duplicates, broken links and thin content, and an SEO analysis feature reports on pages along with performance metrics. It can be run interactively for easy configuration or with all features switched on. Released as open source under the MIT license.
