Deep Dive

Core Capabilities & Architecture

Explore how Real User Monitoring instruments, processes, and correlates high-cardinality telemetry at scale.

Core Web Vitals

Monitor the metrics that define user experience

Track Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) in real time across browser versions, device types, and network tiers.

  • Automatic Core Web Vitals collection across 75th and 95th percentiles
  • Breakdown by geography, device type, operating system, and browser
  • Page navigation timing breakdown from DNS to DOM interactive
  • Alert when vital degradation exceeds performance budgets

Session Replay

See exactly what users experienced before an error

Watch high-fidelity session replays synchronized with console logs, network requests, and DOM mutations, with privacy masking applied before data leaves the browser.

  • DOM mutation recorder with configurable text and input masking
  • Zero PII capture: credit cards, passwords, and sensitive fields obscured
  • Network request timings and payload status codes recorded
  • Jump directly from user clicks to correlated backend traces

Frontend Errors

Diagnose client-side JavaScript crashes with sourcemaps

Unminified stack traces show the exact line in your source repository where an unhandled exception occurred, grouped by error fingerprint.

  • Automatic sourcemap de-obfuscation via CI/CD artifact upload
  • Error fingerprinting groups duplicate stack traces automatically
  • User impact score shows affected user percentages
  • Direct link to backend API trace for 5xx network responses

Built for every team that cares about reliability

One platform, tailored to how your team actually works.

Frontend engineers

Debug UI bugs faster

Inspect unminified stack traces and session replays without asking users for repro steps.

Product managers

Track real user speed

Measure how page load speed and Core Web Vitals correlate with conversion funnel metrics.

SRE & Platform leads

End-to-end visibility

Trace a click in the browser all the way to a slow database query in the cluster.

Under the hood

Lightweight, privacy-first browser SDK

The aiAxonIQ browser SDK adds under 12KB gzip overhead, uses requestIdleCallback for telemetry batching, and encrypts payloads before transport. No third-party cookies, no tracking pixels, full GDPR compliance out of the box.
