Your Worker can now have its own cache in front of it

We are launching Workers Cache, a regionally tiered cache that sits directly in front of your Worker entrypoints. Infinitely composable, configured via standard HTTP headers

Why this matters
Why now

The continuous growth of serverless architectures and the demand for enhanced performance and reduced latency for edge computing applications are driving this innovation.

Why it’s important

This development allows developers greater control over caching strategies, potentially leading to significant improvements in application performance, cost efficiency, and user experience for serverless workloads.

What changes

Developers can now implement a more granular and efficient caching layer directly within their Cloudflare Workers, moving beyond traditional content delivery networks and optimizing for dynamic, serverless functions.

Winners
  • · Cloudflare
  • · Serverless Developers
  • · Edge Computing Providers
  • · Companies reliant on distributed applications
Losers
  • · Laggard serverless platforms
  • · Traditional CDN providers without integrated edge compute caching
Second-order effects
Direct

Improved performance and reduced operational costs for applications deployed on Cloudflare Workers due to optimized caching.

Second

Increased adoption of serverless architectures and a shift towards more complex, performant applications at the network edge.

Third

Potential for new developer tools and services that leverage distributed, programmable caching at the global edge.
