Know the moment your website goes down
Every few minutes your site is checked from outside, the way a customer would reach it. If it stops answering, you hear about it before your customers tell you, and again when it is back.
Alerts where you are
Email, or a message in Slack, Discord or Teams. Only after failed checks in a row, so one slow answer never wakes you.
Response times
How fast your site answered over the last day, and its uptime over a day, a week and a month.
Certificate warnings
A reminder two weeks before your SSL certificate runs out, so visitors never see a security warning.
A status page
A public page showing customers what is working and 90 days of history, without your addresses or errors.
Questions people ask
What does it check?
That the address answers with a success code, within the time you allow, and if you like that the page contains a word you choose, such as Add to cart, which catches pages that load but show an error.
How often?
Every 5 minutes on the Free plan, or every minute on paid plans.
Can it check an API?
Yes: any web address, with the code you expect it to answer with.
Is it free?
Yes, for three addresses checked every 5 minutes, with alerts and a status page. Paid plans watch more, more often.
