AUTOMATION MONITORING FOR AGENCIES

Stop finding out from your clients when something breaks.

Your clients pay you because their automations run reliably — Make.com scenarios, n8n workflows, AI agents, scheduled scripts. When one breaks silently with no human watching, Hellhound catches it before your client does.

Silent failures

Your Make.com scenario runs, Make.com says success, but the output is empty or wrong. Traditional uptime monitors never even looked. Hellhound does.

schedule

You were not watching

Most agencies don't have the time to audit every execution log every morning. Autonomous automations — AI agents, scheduled scripts, Make.com scenarios — run around the clock with no one watching. Hellhound watches 24/7 so you don't have to.

error_outline

Success is not correct

A status 200 just means the request went through. Hellhound monitors what actually came back — output length, format, and content signals — compared to what your automation normally produces.

How it works

01

Connect

Two ways to connect. CLI: wrap any script or agent with one command — zero code changes. Webhook: add two HTTP modules to your Make.com, n8n, or Zapier scenario — five minutes, no code required.

02

Learns

After 10 runs Hellhound knows exactly what normal looks like for your automation — duration, output size, and format. Every run after that is compared against that baseline.

03

Alerted

When something looks wrong we alert you immediately — email, Slack, or SMS. You fix it before your client notices anything happened.

What Hellhound catches across every stack.

  • checkCrashes and non-zero exit codes — immediate alert
  • checkOutput 90%+ shorter than your baseline — something is seriously wrong
  • checkRuns taking 10x longer than usual — automation is stuck or frozen
  • checkOutput format changed — was JSON, now plain text
  • checkLong-running automations gone quiet — heartbeat monitoring detects frozen or dead processes
  • checkSame output every run — possible stuck loop
  • checkError keywords in any log format — "failed", "error", "timeout" detected automatically
  • checkMissed scheduled runs — silence where there should be output

Everything in one dashboard.

Every automation you monitor appears in your Hellhound dashboard. See live status, run history, anomaly logs, and alert history — all in one place. Check in from anywhere. Or don't — Hellhound will tell you when something needs your attention.

✓

Live status — see which automations are running, healthy, or have anomalies right now

✓

Run history — every run logged with duration, output size, status, and any anomaly reasons

✓

Alert log — see every alert sent, when it was sent, and to which channel

Works with every automation stack. Changes none of them.
