Browser Monitoring

Every step. Every network request. Captured as OTEL.

A browser journey is not a black box. Every span, from first-mile DNS to edge TLS, origin backend, and client render, is a verifiable hop.

Set up fast. Build multi-step tests that go beyond the browser.

Start from a URL and ship monitors in minutes—not a long scripting project. You define the steps: combine browser interaction with API calls, workflows, and dependencies so one synthetic journey exercises the full path your customers take.

• Add a URL, tune headers and assertions, and schedule without brittle scripts
• Chain browser steps with APIs and workflow checks in a single test
• Preview and validate before scheduling
• Private nodes for WAF-protected and pre-production environments

Field-grade vitals from every region, continuously.

LCP, INP, CLS, TTFB, and FCP are tracked per journey, per region, and per release. Correlate regressions to the exact deploy.

• LCP, INP, CLS, TTFB, FCP tracked per step
• Per-region and per-device thresholds
• Deploy markers and regression detection

Route the right context to the right team, fast.

When something breaks, get alerted immediately via webhooks, OpenTelemetry, or your existing observability toolchain — with a context-rich payload and full page-level waterfall to investigate.

• Webhook and OTEL-compatible alert delivery
• Full page-level waterfall for investigation
• Route to the right team with specific incident context
• Share reports with stakeholders seamlessly

Everything you need in production.

• Core Web Vitals: Track LCP, TTFB, and other key metrics per journey, per region, and per release.
• 125+ locations: US, EU, LATAM, APAC, and MEA coverage from the same networks your customers use.
• Private locations: Run the same journeys inside your VPC against staging or WAF-protected apps.
• Page-level waterfalls: Full waterfall and OTEL trace on every run, ready for your APM.
• Chrome DevTools import: Import recordings directly from Chrome DevTools. No proprietary scripting format.
• Smart alerts: Alert on consecutive failures from multiple regions, not noisy single-run flakes.
