MetricTrail vs Amplitude
Amplitude is a platform.
MetricTrail is the one dashboard you actually open daily.
Amplitude bundles product analytics, experimentation, and CDP-adjacent tooling into one broad platform. If what you actually need is why visitors leak — real Core Web Vitals, real React errors, and real conversion, correlated — MetricTrail ships a fraction of the JavaScript and skips the platform setup.

When Amplitude is actually the right call
To be direct: if you need built-in experimentation, a broad behavioral platform, and are fine with the extra SDK weight and setup, Amplitude's breadth is hard to match. MetricTrail is narrower on purpose — Web Vitals, errors, and conversion, correlated, in a SDK small enough that it doesn't show up in your own performance budget.
