How uptime monitoring works
There was once a time when a business had a website, and it was up or down. As a developer or administrator, it was easy to keep track of what was going on, and you could step-in to fix problems when they became obvious. Today, that same business will have a website, a docs site, a blog, a storefront, a status page, marketing sites, micro sites and legacy monoliths. We created Cronitor Checks for the developers that support all this fragmentation and still deliver a professional, high quality experience for their customers and stakeholders.
Checks can be created from our dashboard, API or SDK to globally monitor your websites and APIs, so you can stay ahead of any issues that come your way, including:
- Your host is unreachable
- Your SSL Certificate is about to expire
- A (500) Internal Server Error occurs
- The request times-out
- The response does not contain your expected content
Of course, there's a lot more to it than that, and Cronitor gives you everything you need for website and API monitoring, including:
Website monitoring
Ensure that your website is available all over the world and be alerted instantly when there is downtime.
API monitoring
Check the uptime, performance and validity of your APIs with active monitoring.
Server monitoring
Setup checks for the SSH bastions, email servers and VPN endpoints you rely on.
JavaScript? No problem
Run your website checks using real Chrome browsers to test your JavaScript apps.
Custom assertions
Build complex tests with custom assertions on page content, status code, response time and more.
Choose your locations
Select up to 12 locations for each test and focus your monitoring where your users are located.
Check every 30 seconds
Frequent checks can spot small problems before they become big incidents.
Real performance insights
Answer questions and monitor your SLAs with global and regional performance metrics.
No false alarms
Downtime is always verified by at least one additional region before an alert is triggered.
Developer friendly
Provision and version control your monitoring using our simple YAML configuration and CLI tools.
Live dashboards
See all of your APIs, websites and servers on a fast, easy to use dashboard with live updates.

"Cronitor has increased our Operations staff's efficiency and responsiveness immensely. Their spin on micro-monitoring represents a best-in-class solution to the age old problem of visibility."
Ethan Erchinger Director of Operations
"I was finding too many cases where our cron jobs would silently fail - we sometimes would not find out for days that a job was broken. Cronitor gives our team the confidence and peace of mind that if a job is not running, we'll know fast."
Gary Malouf VP of Technology
"Before we used Cronitor, we had an important data backup job fail silently for over a month. We use Cronitor so that will never happen again!"
