Capabilities

Detect downtime before your customers do.

Most monitoring tools tell you everything. Vantaj tells you what matters.
HTTP Monitoring
Global consensus. Vantaj verifies every failure from 3+ nodes before triggering an incident.
Multi-region probes
Checks run simultaneously from Frankfurt, Virginia, and Singapore. Know instantly if it's a regional blip or a full outage.
Instant alerts
Email, Slack, or Discord the moment a check fails. First failure triggers immediately - recovery closes the incident automatically.
False Positive Prevention
Multi-region consensus means every failure is confirmed from all regions before an alert fires.
Public Status Page
A hosted status page your customers can bookmark, with incident history. zero code required.
Incident Correlation
Origin discovery. Trace concurrent failures to their root cause. See exactly where the cascade began.
What engineers say

Trusted by teams who can't afford downtime.

From indie hackers to engineering leads, here's what they say after switching.
“

We used to find out about outages from our customers. Now we know within 30 seconds, before anyone's even thought about opening a support ticket.

False-positives in the past made our team not take alerts and pages seriously. With Vantaj, the multi-region consensus cut our false-positive pages to zero. My on-call rotation now knows that when they're paged, it's actually for a good reason.

Set up my first monitor in 90 seconds, had a public status page live in two minutes. No code, no config. Worth every penny.

Checkout went silently down on a big sales day. We knew in under a minute and had root cause identified before carts were abandoned.

Finally, a tool that treats heartbeat monitoring as first-class. Our cron jobs haven't gone silent undetected since we switched.

The SSL expiry alerts alone paid for the subscription. Would have taken down enterprise customers' custom domains without them.
