Amazon CloudWatch Synthetics adds multi-browser support in AWS GovCloud (US) Regions

Amazon CloudWatch Synthetics multi-browser support is now available in the AWS GovCloud (US-East, US-West) Regions. This expansion enables customers in these two regions to test and monitor their web applications using both Chrome and Firefox browsers.

With this launch, you can run the same canary script across Chrome and Firefox when using Playwright-based canaries or Puppeteer-based canaries. CloudWatch Synthetics automatically collects browser-specific performance metrics, success rates, and visual monitoring results while maintaining an aggregate view of overall application health. This helps development and operations teams quickly identify and resolve browser compatibility issues that could affect application reliability.

To learn more about configuring multi-browser canaries, see the canary docs in the Amazon CloudWatch Synthetics User Guide.
