Vercel Speed Insights Privacy & Compliance

To ensure that the Speed Insights feature can be used despite many different regulatory limitations around the world, we've designed it in such a way that it provides you with information without being tied to, or associated with, any individual visitor or IP address.

The recording of data points is anonymous and the Speed Insights feature does not collect or store information that would enable us to reconstruct a browsing session across pages or identify a user.

The following information is stored with every data point:

See our Privacy Notice for more information, including how Vercel Speed Insights complies with the GDPR.

Once you've followed the dashboard's instructions for enabling Speed Insights and installed the @vercel/speed-insights package, it will automatically start tracking data points for your project.

The package injects a script that retrieves the visitor's Web Vitals by invoking native browser APIs and reporting them to Vercel's servers on every page load.

Learn more about the first-party intake data ingestion method, which enables a faster and more reliable experience.

In version 2, Vercel generates a random seed at build time and passes it through dynamic configuration. @vercel/speed-insights uses this seed to build the injected script URL and intake URLs.

The Resilient Intake does not depend on a single predictable URL path for data collection, enhancing reliability and increasing data collection efficiency.
