Web Performance And Core Web Vitals Monitoring | DebugBear
DebugBear is a website performance monitoring service that tracks page speed and Google Core Web Vitals. It combines scheduled synthetic (lab) tests, real user monitoring (RUM) data collected through an analytics snippet, Google Chrome User Experience Report (CrUX) data, and uptime monitoring to help teams identify slow pages, diagnose bottlenecks, and confirm that optimizations hold over time.
Core capabilities include network request waterfalls with correlation to CPU tasks and rendering, filtered debug views for individual metrics, Lighthouse audit dashboards covering performance, accessibility, and SEO, site speed experiments, before-and-after test comparisons, chart annotations, video export, and sharing via link or PDF/CSV export. It also offers custom dashboards, automatic and threshold-based alerts, industry benchmarking, an API for triggering tests and receiving webhook alerts, AI agent prompt generation for tools like Claude Code and Cursor, and a Slack integration.
DebugBear is aimed at developers, marketing and technical SEO teams, digital agencies, ecommerce stores, and enterprise accounts. It offers a free trial without requiring a credit card, and supports single sign-on for an additional fee. The service is SOC 2 compliant.
