Cloudflare ships Workers Cache for every Worker

Sources: Cloudflare blog, HN discussion
Summary: Cloudflare announced Workers Cache on 2026-07-06, a regionally tiered cache that sits in front of a Worker so that on a cache hit the Worker code never runs. It is available to every Worker on any plan, enabled by adding "cache": { "enabled": true } to wrangler.jsonc, and controlled through standard response headers such as Cache-Control. It uses a lower tier in each data center and an upper tier aggregating across the network, and follows the Worker across custom domains, workers.dev, service bindings, previews, and Workers for Platforms tenants.
Why it matters: Server-rendered Workers can cache rendered responses on a chosen TTL instead of choosing between slow full prerenders and rendering every request.
