Raygun covers three monitoring disciplines in one product: crash reporting for errors, Real User Monitoring for front-end performance as actual visitors experience it, and application performance monitoring for the server side.
Having all three together is the practical argument. A slow page is a front-end symptom of a back-end cause more often than not, and chasing that across two vendors with different session identifiers is where debugging time disappears. AI Error Resolution is the AI layer, moving crash reporting past detect-and-diagnose toward suggesting the fix – which is where the time actually goes once an error is reproduced.
Real User Monitoring deserves particular note: synthetic tests measure a lab, while RUM measures the devices and networks your users actually have. As with any monitoring tool, weigh what error payloads may contain before deployment – crash reports can carry user data.
