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
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.
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.
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.
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.
