Your AI on-call engineer. Without hiring a team.
Sentinel monitors your workflows 24/7, triages alerts at 3am, catches cost anomalies before the invoice, and writes daily briefings so you wake up to a clear picture. Same throughput as a senior DevOps hire. Starts at $299/month.
This is the console you wake up to.
One screen: what fired overnight, what Sentinel healed on its own, and the one thing that actually needs you.
Quiet night. 47 jobs ran, all green. One cost spike on the enrichment workflow (auto-flagged, within budget). A stuck cron self-healed at 22:07. Nothing needs you this morning, so you're clear to focus on product.
A real view of the Sentinel overview. Your data, your workflows, your overnight shift, all in one place.
What it does
Sentinel runs in the background. It watches, diagnoses, fixes the routine, and escalates only what genuinely needs you.
24/7 monitoring
Every cron, webhook, scheduled job. If something stops firing, you know before customers notice.
Tier-1 triage
Filters false positives, runs known runbooks, only wakes you on genuine sev-1 incidents.
Cost anomaly detection
7-day rolling baseline per workflow. A 3x spike in API costs hits your inbox in an hour, not when the invoice arrives.
Daily briefing
One paragraph at 08:00 local: what fired overnight, what was healed, what needs you today. Written like a senior engineer handing off shift.
Self-healing
Common failure patterns (stuck workflow, backed-up queue, drifting DB connection, expiring cert) trigger autonomous remediation.
Audit-ready log
Every alert, every action, every escalation logged immutably. Compliance review is a 10-minute export.
Who buys Sentinel
For operators who can't afford a dedicated DevOps engineer but can't afford NOT to have one watching the systems.
You ARE the on-call team
Sentinel takes the night shift. You focus on product + customers. Your weekends come back.
2-3 engineers running 50+ workflows
Sentinel + your team = the leverage of a 5-person ops team. They handle architecture; Sentinel handles routine.
Managing client infrastructure
White-label Sentinel under your brand. Clients get 24/7 monitoring; you get margin without hiring a SOC team.

Let's do the math
A senior DevOps hire costs around $180K a year plus benefits. Sentinel Growth covers most of that everyday work for $12K a year.
| Your option | Cost per year | What you get |
|---|---|---|
| Sentinel Growth on its own | $12K | Handles most of the everyday work. You only step in for the big architecture calls. |
| One senior DevOps engineer | About $240K | 40 hours a week, and they still burn out being on call. |
| Sentinel Growth plus one engineer | About $252K | The output of five engineers, with nobody stuck on call at 3am. |
| Five engineers for full coverage | About $1.2M | Round the clock cover, plus the cost and overhead of managing a team. |
"I built Sentinel because I was the one getting woken up at 3am. I run a lean operation and couldn't afford a DevOps team, but I couldn't afford an outage either. So I built the engineer I needed."
