All In One Website Monitoring

Know about issues on your website before they impact users and your business.

Onemon.io is an online tool for automatic and comprehensive website monitoring. Every minute, from different geographical locations we ensure that everything is fine with your website. When we detect any problem, we will let you know before your users do.

Key Aspects

Everything you need in a single tool.

Real Browser Tests
In addition to standard tests, we regularly check webpages in a real browser. We load them just like your users and verify all their components.
Domain, Certificate and Safety
You will be notified when a domain or certificate is about to expire or if there are any issues with the certificate. We also check safety.
Script Errors Monitoring
Most websites depend on JavaScript code. If it malfunctions, so does the website. That's why we check them also for JavaScript errors.
Personal and Team Notifications
You will be notified of any problems with your website. We provide fast and reliable notifications for you and your team.
