{"slug":"best-synthetic-monitoring-tools-for-multi-step-browser-journeys","title":"Best synthetic monitoring tools for multi-step browser journeys","question":"What are the best synthetic monitoring tools for multi-step browser journeys in 2026?","verdict":"As of 2026-09-06, Claude and Gemini collectively rank Checkly #1 for synthetic monitoring tools for multi-step browser journeys on ModelsAgree by aggregate score. The models' case: Native Playwright execution allows testing complex multi-step browser journeys as version-controlled code (Monitoring as Code), providing local CLI parity and complete. The models' main caveat: Strictly code-centric workflow with no codeless recorder for non-technical users, and it lacks native backend APM distributed tracing without external. The strongest alternative is Datadog Synthetic Monitoring — Best-in-class managed multi-step browser tests with a recording-based editor plus assertion/variable steps, robust self-healing locators, subtests for. Not unanimous: Claude picks Datadog Synthetic Monitoring.
