Query Speed Insights from the Vercel CLI
Vercel just gave coding agents direct access to production performance data. That changes how teams debug at scale.
Why it matters
Vercel's CLI now exposes Speed Insights metrics to agents, enabling autonomous performance monitoring and debugging workflows. This is a capability layer built on top of existing tools—relevant to founders building agent-first development platforms.
The key facts
11 to knowVercel CLI now supports querying Speed Insights datapoints directly
Supports Core Web Vitals (LCP, INP, CLS) and additional metrics (FCP, TTFB)
Based on client-side measurements from real user traffic
Enables coding agents to autonomously answer performance questions
Use cases: regression detection, geo-performance analysis, device comparison
Vercel CLI now supports direct Speed Insights queries via 'vercel metrics' command
Core Web Vitals accessible: LCP, INP, CLS
Secondary metrics: FCP, TTFB
Agent-ready: CLI queryable by coding agents for autonomous performance monitoring
Supports filtering by dimension, region (e.g., Asia), and device type (mobile/desktop)
Use cases: trend analysis (week-over-week regression), geographic performance, cross-platform comparison
