Rules - Custom Errors are now Generally Available

Custom Errors are now generally available for all paid plans — bringing a unified and powerful experience for customizing error responses at both the zone and account levels. You can now manage Custom Error Rules , Custom Error Assets , and redesigned Error Pages directly from the Cloudflare dashboard. These features let you deliver tailored messaging when errors occur, helping you maintain brand consistency and improve user experience — whether it’s a 404 from your origin or a security challenge from Cloudflare. What's new: Custom Errors are now GA – Available on all paid plans and ready for production traffic. UI for Custom Error Rules and Assets – Manage your zone-level rules from the Rules > Overview and your zone-level assets from the Rules > Settings tabs. Define inline content or upload assets – Create custom responses directly in the rule builder, upload new or reuse previously stored assets. Refreshed UI and new name for Error Pages – Formerly known as “Custom Pages,” Error Pages now offer a cleaner, more intuitive experience for both zone and account-level configurations. Powered by Ruleset Engine – Custom Error Rules support conditional logic and override Error Pages for 500 and 1000 class errors, as well as errors originating from your origin or other Cloudflare products . You can also configure Response Header Transform Rules to add, change, or remove HTTP headers from responses returned by Custom Error Rules. Learn more in the Custom Errors documentation .
