# LightKeeper > LightKeeper is a regional website performance and availability audit service for teams that need to understand how a URL loads from different parts of the world. It helps product, SEO, and engineering teams compare regional Lighthouse evidence, Core Web Vitals signals, screenshots, network details, and shareable reports before and after fixes. LightKeeper focuses on practical diagnostics for websites that may behave differently by location because of CDN routing, DNS, edge rules, redirects, localization, third-party scripts, or regional blocking. The product is useful when a page works locally but is slow, unavailable, redirected, or incomplete for users and crawlers in another region. The primary workflow is to submit a URL, run regional checks, compare results, and share the evidence with people who need to make or verify a fix. Free audits provide a quick regional baseline. Premium report views expose deeper evidence for engineering diagnosis. ## Product - [LightKeeper homepage and free audit](https://www.lightkeeper.cloud/): Start a free regional website performance audit and compare how a URL behaves across available regions. - [About LightKeeper](https://www.lightkeeper.cloud/about-us): Project background, creator information, and the product philosophy. ## Developer Context - [Sitemap](https://www.lightkeeper.cloud/sitemap.xml): Search-engine sitemap for public pages. - [Robots.txt](https://www.lightkeeper.cloud/robots.txt): Crawling policy for automated agents.
