Catches regressions on publish
Webflow and HubSpot publishes trigger a synthetic Lighthouse run. If LCP, CLS, or INP regress, we alert the right people in Slack within minutes.
Coming soon · early access
Your marketing team just broke the pricing page. You’ll find out in three weeks.
CorePulse monitors your landing pages and tells you the moment a publish hurts performance — before Search Console does.
No credit card to start. Cancel anytime.
Tells you what changed
When something breaks, CorePulse points at the specific script or image that’s most likely responsible — not just ‘LCP went up’.
Watches GTM rot quietly
A weekly automated audit of your GTM container. Stale tags, duplicates, governance gaps. The same rule engine that powers PageCheckup, on a schedule.
Built for marketing ops, not engineers
No P95 charts. No CI integration. Plain-language alerts your marketing team can act on without paging a dev.
Slack-first, email second
Marketers live in Slack. So that’s where regression alerts land. Email is a fallback, not the main channel.
One Monday digest
A weekly summary of what regressed, what improved, and where GTM health is heading. Short enough to read on a phone.
Stop finding out about page regressions from your CEO.
Connect a Webflow or HubSpot site, pick the pages that matter, and CorePulse takes it from there.
