Caching details now available in Runtime Logs

Vercel News Oct 31, 2025

You can now view more details on how Vercel's CDN globally serves cached content to users as quickly as possible.

In the right-hand panel of the Runtime Logs page, we now list:

  • Cache key: A unique identifier for a specific version of a cached page
  • Cache tags: Tags associated with the cached data
  • Revalidation reason: If a revalidation took place, the reason why the content was being revalidated (time-based, tag-based, or deployment-based)

This is available to all Vercel users at no additional cost. Try it out or learn more about Runtime Logs.
