**Features**:
+ **PlayWright support** – You can write canary scripts by using the Playwright automation framework. You can bring your existing Playwright scripts to run as canaries, and enhance them with AWS monitoring capabilities.
+ **CloudWatch Logs integration** – You can query and filter for logs through the CloudWatch Synthetics console. Each log message contains unique `canaryRunId`, making it easy to search for logs for a particular canary run.
+ **Metrics and canary artifacts** – You can monitor canary run pass rate through CloudWatch metrics, and configure alarms to alert you when canaries detect issues.
+ **Screenshots and steps association** – You can capture screenshots using native Playwright functionality to visualize the stages of a canary script on each run. Screenshots are automatically associated with canary steps, and are uploaded to Amazon S3 buckets.
+ **Multiple tabs**– You can create canaries that open multiple browser tabs, and access screenshots from each tab. You can create multi-tab and multi-step user workflows in Synthetics.
