Uptime Monitoring

Know about downtime before your customers do

Every minute of downtime costs you visitors, revenue, and trust. Our uptime monitoring checks your website every few minutes and alerts you the moment something goes wrong - not when customers start complaining or you notice a traffic drop.

Your site was down for 2 hours. You found out from a customer complaint

Without proactive monitoring, you only discover outages when users complain - or when you check your analytics and see a mysterious traffic drop.

!

You don't know your site is down until customers tell you

!

Partial outages (like slow API responses) go unnoticed

!

SSL certificates expire and browsers show scary warnings

!

You have no historical uptime data for SLA reporting

!

Intermittent issues are hard to catch without continuous monitoring

!

On-call engineers get woken up for problems that resolved themselves

Capabilities

What you can monitor

Continuous Monitoring

We check your site continuously at configurable intervals. Detect outages quickly and track response times over time.

Flexible Check Intervals

Choose check frequencies based on your plan. Agency plans support 1-minute intervals; other plans support 5-minute intervals.

HTTP/HTTPS Monitoring

Monitor any HTTP or HTTPS endpoint. Customize request headers, expected response codes, and even check for specific content in the response body.

SSL Certificate Monitoring

Get alerts 30, 14, and 7 days before your SSL certificates expire. Never let an expired certificate surprise you with browser warnings.

Response Time Tracking

Track server response times (TTFB) from each location. Get alerts when response times exceed your threshold - slow is almost as bad as down.

Instant Alerts

Receive notifications via email or in-app alerts within 60 seconds of detecting an issue. Never miss a critical outage.

Recovery Alerts

Get notified when your site goes down and when it comes back up. Know exactly when issues are resolved, not just when they started.

Uptime Reports

View historical uptime percentages and incident history. Great for SLA reporting, post-mortems, and understanding reliability trends.

Quick Setup

1

Add your endpoints

Enter the URLs you want to monitor. Specify expected response codes, custom headers, and any content you want to verify is present.

Select how often to check your endpoints (1-5 minutes). Higher frequency means faster detection of issues.
