Is Vercel Speed Insights enough for Core Web Vitals monitoring?

Agencies often turn on Vercel Speed Insights for a Next.js client, see route-level Core Web Vitals, and assume monitoring is “done.” For that Vercel project, the product is genuinely useful. For a book of WordPress, Shopify, Magento, and mixed hosts, it is not enough.

For these sites, scheduled lab tests and third-party tools are still necessary.

Speed Insights excels in its ability to provide route-level data on Vercel deployments, offering faster iteration windows compared to field data like PageSpeed Insights. However, it does not replace scheduled lab tests or the need for multi-tenant portfolio monitoring solutions. Agencies often use a split stack approach, utilizing Speed Insights for Vercel projects while relying on third-party tools for other domains.

It is crucial to remember that Speed Insights and PageSpeed Insights are complementary tools, each addressing different aspects of web performance monitoring.

  • Execute all operations client-side without server APIs
  • Offer tools like JSON formatter, JWT decoder, and QR code generator

If You Can't Draw the Boundary, You Don't Have an Architecture

The boundary question ended my whiteboard round before it started. The interviewer asked where my system ended. I listed components. He said I had just described the whole company. He was right.

  • The interview focuses on system boundaries to assess architectural thinking.
  • Team boundaries, not just technical ones, often cause project failures.
  • The 4-seam checklist (auth, payments, third-party data, shell) helps define boundaries.
