PlatformReal user monitoring
See your site the way your users do.
Add one script tag to your web application and measure page speed, Core Web Vitals and JavaScript errors from real visitors' browsers — without cookies or personal data.
What is real user monitoring?
Real user monitoring (RUM) measures your website from the browsers of real visitors: how fast pages load, how quickly the page responds to input, how much the layout shifts, and which JavaScript errors people hit. Lab tests show what could happen; RUM shows what does happen on real devices and networks.
Televane measures Core Web Vitals, page loads and JavaScript errors with one script tag, without cookies and without storing personal data.
