About

Track updates of your entire site. Catch website issues before your users do. Find visual bugs on every page. Studies show up to 85% of visitors are more likely to leave after seeing errors on your site. See how new changes affect the rest of your site and catch any unexpected side effects before it becomes a problem. PageWatch analyzes your website using Lighthouse to identify slow pages that might hurt your conversions. PageWatch is a zero config tool for front-end testing. It allows you to test any site for performance issues, broken layouts, spelling mistakes, broken links and more. You can run PageWatch as part of your continuous integration process. On every pull request or deploy you'll be able to test your site and catch any issues before it becomes an issue. Our Netlify build plugin can run PageWatch audits automatically from pull request previews or production builds.

About

PerfDelta is a web-based website speed testing and monitoring service for SEO specialists, agencies, and in-house web teams. Its free test scans up to three pages on mobile and desktop, combining real-user Core Web Vitals from the Chrome UX Report with Lighthouse lab measurements. Reports compare a site with up to two competitor domains and a benchmark of previously tested sites, show page-weight breakdowns and request timelines, identify site technologies, and estimate savings in prioritized recommendations naming affected files. Paid plans add scheduled monitoring, performance budgets, email alerts, report history, and PDF exports; Agency and Scale plans also provide CSV export, public dashboards, and a REST API. MCP access lets compatible AI agents request tests and retrieve results. Reports can be shared with clients for performance audits and ongoing site work.
