CoreDash
CoreDash is a Real User Monitoring platform built for Core Web Vitals. The product is shaped around LCP, CLS, and INP, the metrics that move search rankings and conversion rates. You install a lightweight script. CoreDash collects performance data from real visitors on real devices and segments it by page template, country, device, connection, or any custom dimension. Element level attribution names the exact CSS selector and phase causing each slowdown. Long Animation Frames data traces INP regressions back to the responsible script. A built in MCP server exposes your field data to Claude, Cursor, ChatGPT, and any AI agent that speaks Model Context Protocol, so you can debug a CWV regression by asking a question in plain English. Privacy is built in. Data is stored in the EU, no consent banner is needed, and visitors stay anonymous by default. Paid plans start at $19 per month.
