This tool runs on the AdminForge server, which needs to reach the target you enter. Nothing is stored or logged. Do not paste secrets into a server-side tool on an instance you do not control.

Fill in the form and run the tool. Results appear here.

Occurrences are computed in the time zone you pick, so a daylight-saving transition shows up in the list as a skipped or repeated run — which is exactly the surprise that breaks nightly jobs twice a year. Pure arithmetic: nothing leaves the instance.
