# Caching details now available in Runtime Logs

By Steven Van · 2025-10-31

Runtime Logs now show a request's cache key, cache tags, and revalidation reason, free for all Vercel users.

The [Vercel](<https://creatorstoolbox.com/tools/vercel>) Logs tab now shows more detail on how content was served from the CDN cache. The right-hand panel on the [Runtime Logs](<https://vercel.com/docs/logs/runtime>) page lists the cache key (a unique identifier for a specific version of a cached page), cache tags associated with the cached data, and, when a revalidation happened, the reason for it: time-based, tag-based, or deployment-based.

The feature is available to all Vercel users at no additional cost.
