Core Web Vitals as a release gate

Lighthouse CI and Real User Monitoring hooks are now part of our default pipeline; budgets fail builds before regressions reach stakeholders.

Analytics dashboard with performance graphs

From best effort to enforced quality

Performance was historically a review checklist item. We changed that by making Web Vitals an automated gate in CI for key routes and interactions.

If metrics drift beyond budget, the pipeline fails with actionable traces so teams can fix issues before release.

How we monitor real users

Synthetic checks alone can hide real-world device/network conditions. We now ship lightweight RUM instrumentation by default to measure user impact in production.

This gives product teams a clearer picture of where latency hurts conversions and retention.
