Query Speed Insights from the Vercel CLI

Vercel now allows users to query Speed Insights datapoints directly through the Vercel CLI, enabling retrieval of core Web Vitals and other page performance metrics from real user traffic. This feature lets developers and coding agents analyze performance regressions, geographic speed, and device-specific metrics using the `vercel metrics` command.

You can now query Speed Insights datapoints directly through the Vercel CLI. Using the vercel metrics command, you can pull core Web Vitals https://web.dev/articles/vitals LCP, INP, CLS and other page performance metrics FCP, TTFB based on client-side measurements from real user traffic. By providing a coding agent access to the CLI, an agent can answer questions such as: Which pages' INP have regressed since last week? How is the perceived speed of my home page in Asia? Compare the CLS of the dashboard between mobile and desktop. For more details on how to use the CLI command and a complete list of supported metrics, dimensions, filters, and query options, explore the documentation https://vercel.com/docs/speed-insights/accessing-metrics-with-vercel-cli .
