Catch regressions early with Synthetic Monitoring

Predictable, repeatable performance testing for your web app under controlled conditions. Powered by SpeedCurve, now in Embrace.

TRUSTED BY LEADING ENGINEERING TEAMS

WHY CHOOSE EMBRACE

Know how your site should perform before real users ever see it

Synthetics gives teams controlled, repeatable tests to catch regressions, validate optimizations, and understand baseline performance, all alongside real user data in Embrace.

Catch performance issues before they reach users.

Synthetics in Embrace helps teams catch performance issues before they reach users. With a focus on clarity and actionability, it gives you:

  • Run tests on demand or on a schedule across URLs, browsers, locations, and network conditions.

  • Track Core Web Vitals and Lighthouse scores to establish a performance baseline and spot regressions over time.

  • Drill into browser waterfall visualizations to see exactly how resources load and where bottlenecks occur.

  • Explore resource breakdowns by type and size to identify what’s adding weight and delaying critical renders.

  • Pinpoint which third-party scripts are consuming CPU and hurting responsiveness.

  • Watch visual render timelines to understand what users see as the page paints and becomes interactive.

Synthetics and RUM, together in one platform

Real User Monitoring shows you how your site actually performed for real users. Synthetics shows you how it performs in controlled, repeatable conditions. Together, they give you the full picture.

  • RUM tells you how real users experience your site across devices, networks, and geographies

  • Synthetics tells you how your site should behave under controlled test conditions.

Use them together to ship faster, catch regressions early, and connect performance improvements to real user impact.
