Hellhound monitors automations beyond “success” status. It detects silent failures by analyzing output, duration, and behavior against a learned baseline — not just uptime or exit codes. Connect via CLI or webhook in minutes, with no code changes. Works across Make.com, n8n, Zapier, AI agents, and scripts. Get alerted instantly when something is wrong — before your client notices.

Hellhound came from a very real problem: automations “succeeding” while actually failing.
We kept seeing Make.com, n8n, and scripts return success (status 200 / exit code 0), but the output was empty, broken, or incomplete. Clients would notice before we did.
Existing monitoring tools don’t look at what actually happened — only whether something ran.
So I built Hellhound to monitor the behavior of automations:
- Output size, format, and anomalies
- Runtime deviations
- Silent failures and stuck processes
It learns what “normal” looks like and alerts when something is off.
Would love feedback — especially from agencies or anyone running automations / AI agents in production.
