Catch regressions
before users do.
Automatically diff Core Web Vitals, JavaScript bundle size, route load time, and error rate between every release. Get alerted in Slack within minutes.
Every release,
before and after.
PagePulse tags every deployment with version, commit, and environment, then diffs Core Web Vitals, JS size, and error rate automatically. Regressions surface within minutes.
Ship it. 4 of 5 affected routes improved. /checkout regressed by 40ms but remains within budget. No rollback required.
From commit to confidence in four steps.
Tag every release
Call PagePulse.deployment from your CI/CD pipeline with version, commit, and environment. PagePulse automatically correlates every RUM sample, every error, and every bundle-size measurement with the release that produced it.
Read the diff
For every release, PagePulse generates a side-by-side diff of LCP, INP, CLS, FCP, TTFB, JavaScript bundle size, route load time, hydration time, and error rate. Statistically significant regressions are highlighted automatically.
Get alerted in minutes
When a release regresses LCP by more than 10%, INP by more than 20%, or CLS by more than 0.05, PagePulse can alert you in Slack, Linear, Jira, or any webhook within five minutes of going live.
Decide: ship or roll back
The deployment diff includes a recommendation: ship it, monitor, or roll back. Every decision is backed by per-route breakdowns and statistical significance, not gut feel.
