Limits
Script limits
Cloudflare provides an unlimited number of scripts for Workers for Platforms customers.
cf object
The cf object contains Cloudflare-specific properties of a request. This field is not accessible in user Workers by default because some fields in this object are sensitive and can be used to manipulate Cloudflare features (for example, cacheKey, resolveOverride, scrapeShield.)
To access the cf object, you need to enable trusted mode for your namespace. Only enable this if you control all Worker code in the namespace.
Durable Object namespace limits
Workers for Platforms do not have a limit for the number of Durable Object namespaces.
Cache API
For isolation, caches.default is disabled for namespaced scripts. To learn more about the cache, refer to How the cache Works.
Tags
You can set a maximum of eight tags per script. Avoid special characters like , and & when naming your tag.
Gradual Deployments
Gradual Deployments is not supported yet for user Workers. Changes made to user Workers create a new version that deployed all-at-once to 100% of traffic.
