Yes it still works.
However, If you are looking for a paid and fully supported synthetic monitoring app that has premium features, consider Active Robot Monitoring https://splunkbase.splunk.com/app/3983/ (disclaimer, I am a developer of this product).
It has screenshots-on-error, waterfall network breakdowns, on-demand script execution, encrypted secrets and support for scheduled downtime. The application is enterprise ready with many large Australian customers. It runs on Windows or Linux and is compatible with Splunk cloud.
