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.
Key features
- Automatically check your websites from multiple global locations every 30 seconds.
- Get notified if your site is down, slow, or returning the wrong content.
- Verify status codes, response time, keywords, and headers.
- Integrate with Slack, email, SMS, phone calls, and more for alerts.
- Track uptime and response performance over time.
