Tickmark

Tickmark watches for the pings your scheduled jobs should send. When the backup, the certificate renewal or the sync job goes quiet, you hear about it — that is the entire, essential idea.

Worth knowing before you commit:

• Integrating a job is one line: hit a unique URL when it finishes.
• Grace periods keep slightly-late jobs from waking you.
• The absence-of-signal model catches failures crash loops hide.

Every homelab has silent jobs. This is how they stop failing silently.
