Write regex using natural language in Cloudflare One

Cloudflare Gateway policy selectors which support regular expressions can now be authored in the dashboard using natural language. When building a policy with a regex-based selector (like matches regex), you can describe what you want to match in plain English and the Cloudflare Agent will generate and validate a corresponding regular expression.

To get started, select a regex-compatible selector in the Gateway policy builder and select the icon. You'll see an input field for natural language, such as "any URL starting with /api/v1" or ".com, .net, and .app hosts which contain gooogle in the host."

You can also use the tool to explain existing regular expressions. If a policy already contains a regex pattern, you can instantly generate a plain-language description.

A built-in feedback mechanism allows you to rate each interaction to help improve output quality over time.
