Simplifying runtime caching on Vercel
Today, we’re bringing Data Cache into Runtime Cache, giving developers one product for data caching across frameworks and APIs.
If you use Next.js fetch caching or unstable_cache, you won’t need to change your code. Pro and Enterprise projects will get larger storage allocations.
Runtime Cache lets your code reuse fetched or computed data across requests without operating a separate caching service. Over the past year, we’ve improved read performance during traffic bursts, increased storage budgets, and made cache usage easier to investigate.
Why we built Runtime Cache Data Cache was originally launched as Vercel’s data caching service for the Next.js App Router, used by fetch caching and unstable_cache. Unlike CDN caching, which stores complete HTTP responses, Data Cache stores data your application uses to generate those responses. A product page, for example, can reuse cached catalog data while rendering a personalized response for each visitor.
