PubPerf

Turn performance into a daily habit: connect your site, add the lightweight snippet or SDK, and watch real visitor data roll in within minutes. PubPerf builds a live UX dashboard that highlights where people lose time—by device type, geography, page template, and route. You’ll see key speed signals, third‑party impact, and request waterfalls in one place, so you can spot slowdowns, regressions, and flaky tags before they hurt conversions.

For developers and QA, set baseline budgets for metrics you care about and wire them into CI/CD. Run synthetic checks on key user journeys (signup, search, checkout) before and after each deploy, then compare results to the previous release. Tag Governance tracks every third‑party script: load time, execution cost, and error bursts. If a marketing pixel or A/B tool introduces jank or exceptions, you’ll see the delta per release, the exact script URL, and the call stack that changed. Use the diff view to decide whether to defer, remove, or isolate a tag—no guesswork.

Create alert rules tailored to your stack and audience. Trigger on sustained slow LCP for mobile in a specific region, a spike in TTFB on product pages, or a jump in JavaScript errors from a new tag. Route alerts to Slack, Teams, PagerDuty, email, or webhooks; add quiet hours and deduplication to avoid noise. When something trips, PubPerf includes context: which deployment happened, which tag or resource shifted, sample sessions, and a timeline you can share with one link. Post‑incident, annotate the dashboard with fixes so future releases are easier to evaluate. more
