Uptime Monitoring

Know before your customers do

Vantaj is a website uptime monitoring tool that runs HTTP checks from multiple global regions on a schedule you control, detecting downtime in seconds and alerting your team before users notice.

Global probe network

Checks run simultaneously from US East (Virginia), Europe (London), and Asia Pacific (Singapore). A confirmed multi-region failure triggers an incident; single-probe blips do not.

Sub-minute detection

Check intervals as fast as 30 seconds on paid plans, down to 5 minutes on free. Shorter intervals mean faster detection and faster response.

Response time tracking

Track latency percentiles over time. Catch performance degradation before it becomes a full outage.

Multi-channel alerts

Email, Slack, Discord, or webhooks. Route alerts to the right person on the right channel with configurable alert policies.

Incident timeline

Every outage creates a structured incident record with start time, affected regions, resolution time, and total duration.

Full HTTP control

Custom headers, request bodies, status code assertions, and keyword matching. Monitor any endpoint, not just simple pings.

How it works

01 - Add a monitor

Paste a URL, we handle the rest

Add any HTTP/S endpoint in seconds. Set your check interval, expected status code, and alert contacts. No agents to install, no DNS changes required.

02 - Global verification

Multi-region consensus before alerting

When a check fails, Vantaj immediately re-checks from all configured probe regions (US East, Europe, Asia Pacific). Only a confirmed multi-location failure triggers an incident.

03 - Instant notification

Your team knows within seconds

Alerts land in Slack, email, or Discord the moment an incident opens. Recovery notifications fire automatically so your team knows the issue is resolved without refreshing dashboards.

04 - Full history

Uptime data you can show customers

Every check result is logged: up to 90 days on Developer and 6 months on Team plans. Calculate SLA compliance and document your reliability with real monitoring data.

Frequently asked questions

What is uptime monitoring?
Uptime monitoring automatically checks whether your website, API, or service is reachable and responding correctly. Vantaj sends regular HTTP checks from multiple regions and alerts your team the moment a check fails.
How often does Vantaj check my site?
Check intervals go down to 5 minutes on the Free plan, 1 minute on Developer, and 30 seconds on Team. Shorter intervals mean faster detection and faster response.
How does Vantaj avoid false-positive alerts?
Every failure is re-checked from all configured probe regions (US East, Europe, Asia Pacific). An incident only opens when the failure is confirmed from multiple regions, so a single-region network blip never pages your on-call.
Is there a free uptime monitoring plan?
Yes. The Free plan covers up to 20 monitors with 5-minute checks and email alerts - no credit card required. You can upgrade when you need faster intervals or more channels.
Which channels can Vantaj alert on?
Email, Slack, Discord, and webhooks. Alerts fire the moment an incident opens, and recovery notifications close it automatically so your team knows when the issue is resolved.
