Questions people actually ask

What happens if Silent Fail itself goes down?

Then alerts are not being evaluated, and pretending otherwise would make this whole product dishonest. Every run of the checker is recorded, so the dashboard shows a warning when the last run is more than five minutes old, and the same signal is exposed at /api/health as JSON. Point an external uptime check at that endpoint and you are monitoring the monitor, which is the only arrangement that closes the loop. A monitoring tool that claims it cannot fail is the one you should not trust.

Does this need access to my workflow or its data?

No. There is no OAuth, no platform connection and no read access to anything. Your workflow makes one HTTP request to a URL when it finishes, and that request needs no body, so there is nothing in it for us to read. We record the time it arrived, the HTTP method, the source IP and the user agent, which is what lets you confirm the wiring works. We never see what your automation does or what it moves.

What if my schedule is irregular?

Set the expected interval to the longest gap that is still normal and let the grace period absorb the variance; it defaults to twice the interval, which tolerates a lot. For a job that runs once a day at no fixed time, use a daily schedule with a deadline late enough to cover the spread. Being straight about the limit: if a workflow genuinely runs at unpredictable intervals with no upper bound, a deadline-based check is the wrong tool, because there is no deadline to set.

How many emails will I get for one outage?

Two. One when the deadline passes and one when pings resume. The checker runs every minute while a monitor is down and stays silent for all of those runs after the first: the delivered alert is recorded, and that record is what suppresses the rest. The all-clear clears it, so the next outage can alert again. Ten monitors failing means ten emails, but one monitor failing for a week is still one email.
