Implementing synthetic monitoring using Amazon Nova Act
Amazon Nova Act lets you run synthetic UI tests with a single natural‑language command, cutting selector maintenance and boosting reliability.
Why Now
The article explains a new agent‑driven synthetic monitoring approach using Amazon Nova Act and Bedrock AgentCore, released as a how‑to guide on 28 Sep 2026.
What Happened
Nova Act uses a multimodal LLM that interprets UI screenshots instead of DOM selectors, achieving over 90% accuracy in early enterprise tests. It replaces brittle selector scripts with just three natural‑language actions per workflow. The solution integrates EventBridge Scheduler, AgentCore Runtime, and SNS for scheduling and alerting.
Why It Matters
By eliminating selector maintenance, teams can run more frequent, reliable journey checks, reducing downtime for critical e‑commerce or SaaS flows. It also lowers operational costs by removing the need for dedicated browser farms.
The Limitation
The 90% accuracy figure comes from early enterprise use cases; real‑world performance may vary and retries may still be needed for edge cases.
What You Can Do
Try building a simple synthetic monitor with Nova Act and AgentCore on your own site and compare maintenance effort to your current Selenium scripts.
