Know when your project goes down
You built something real. Users are paying. Your side project deserves the same monitoring that production systems run on — and with 20 free monitors, you probably won't pay a cent.
The problem
A user DMs you on Twitter to say your site is down — you had no idea
Your SSL cert expired on a subdomain you forgot about and users see a browser warning
Your nightly cron job silently stopped running three weeks ago
You're on vacation when the server crashes and nobody notices for two days
How Vantaj helps
Zero false alarms
Vantaj checks from 10 regions. An alert fires only when multiple probes agree the target is down. No 3 AM pages for a network blip.
Status page included
A public status page goes live automatically. Give your users somewhere to check instead of flooding your inbox during an outage.
Cron job monitoring
Add one HTTP call to the end of your scheduled jobs. Vantaj alerts you when a job stops running on schedule — before your data goes stale.
SSL & domain expiry
Vantaj tracks expiry dates and alerts you 30 days out. Your users won't see a browser warning because you forgot to renew.
Slack, Discord, or email
Alerts go wherever you already pay attention — Slack, Discord, Telegram, email. Set up in under a minute.
20 monitors free
The free tier covers 20 monitors, a public status page, and 5-minute check intervals. No credit card. No trial period. No expiry.
Cover your key endpoints
Start with your homepage, login route, and API. Add your SSL certificate and domain to catch expiry before users do. Takes under two minutes.
Give users somewhere to look
Your public status page is live as soon as you add a monitor. Share the URL in your app footer or README. It absorbs a lot of "is it down?" messages.
Alerts reach you where you already are
Incidents post to your channel the moment they open. Recoveries post when the service comes back up. You stay informed without checking a dashboard.
Catch silent failures in background tasks
Paste one line at the end of each scheduled task. If it doesn't ping Vantaj on time, you get an alert. Works for any language, any host.
