One platform, not four
Monitoring, status pages, incidents, and alerts - all built in.
Alerts where you already work.
Get notified the moment something breaks - in the tools your team already uses.

One-click importers bring over your monitors, keyword checks, and heartbeats with a read-only API key - no CSV exports, no re-typing URLs. Coming from somewhere else? Bulk import via CSV.
Trusted by teams who can't afford downtime.
From indie hackers to engineering leads, here's what they say after switching.
Switched from UptimeRobot after getting woken up twice in one week for nothing. Been on Vantaj for 3 months now - haven't had a single false page.

The multi-region thing isn't just marketing. We had a genuine Frankfurt-only outage last month and Vantaj caught it while our old tool would have just shown 'degraded' from one probe.

Setup took maybe 90 seconds? Pasted our API URL, picked Slack for alerts, done. Status page was live before I finished my coffee.

Solo founder · Sheetbase
We monitor 15+ client sites on the free tier. When one of them went down at 2am, we knew before they did. That's the kind of thing that keeps contracts.
Rachel Torres
Technical Director · Pixel & Code Agency
Honestly just needed something that works and doesn't cost $100/mo for basic monitoring. Vantaj is that.
Daniel Kowalski
CTO · Firmstack
Our cron jobs used to fail silently for hours. Heartbeat monitoring caught a stuck payment processor within 2 minutes of it going quiet.

Frequently asked questions
Everything you need to know before your first monitor goes live.
Yes. Up to 20 monitors, free forever - it's a plan, not a trial. No credit card required, and you keep multi-region checks, alerts, heartbeats, and a public status page on it.
Checks run as often as every 30 seconds from multiple regions. The first confirmed failure triggers your alerts immediately - and when the check recovers, the incident closes automatically.
Websites and APIs over HTTP(s) with keyword and status-code assertions, servers via ping, TCP ports, SMTP mail servers, and cron jobs or background workers via heartbeats. SSL certificate and domain expiry tracking are built in too.
Connect Slack, email, Discord, Telegram, Microsoft Teams, Google Chat, OpsGenie, Zapier, Linear, or any webhook once - then alert policies decide who gets notified and when, including timed escalation steps if an incident stays open.
Every failure is confirmed from multiple independent regions before an alert fires. A single network blip between one probe and your server never pages your on-call.
Yes - one-click importers for UptimeRobot, Pingdom, StatusCake, and Better Stack bring your monitors over with a read-only API key in about a minute. Anything else can come in via CSV upload.
Every plan includes hosted status pages - public or private, with your logo and colors, incident updates, email subscriptions, embeddable badges, and custom domain support.
No. Vantaj checks your services from the outside, so there are no agents, SDKs, or code changes. Paste a URL and your first monitor is live in under a minute.
