Website Monitoring

Website monitors let you automatically check your websites or web applications and get alerted when they become unavailable, respond slowly, or return unexpected results. This ensures your users always have a smooth experience.

Just like with other monitors, when a website monitor detects a problem, you can collaborate with your team to resolve the incident and optionally update your status page.

A website monitor succeeds when all configured conditions are met.
You can define one or more of the following assertions:

  • Status code: e.g. response is 200 OK
  • Response time: e.g. under 2 seconds
  • Body contains: e.g. “Welcome to our site”
