Synthetic Monitoring
Proactive website monitoring that simulates user journeys from external locations using scripted browser sessions on a scheduled basis.
Synthetic monitoring (also called active monitoring or lab monitoring) runs scripted tests against a website at regular intervals to measure performance and availability. Unlike RUM which captures real user data, synthetic monitoring is controllable — tests run in the same conditions every time, making it ideal for regression detection. AuditJet's core monitoring is synthetic — running Lighthouse on a schedule.
