About OpenPolicy
PolicyStack is an open source, AI first toolkit that turns one typed TypeScript configuration into a privacy policy, a cookie policy and the consent state that gates the cookies those documents describe, rendering them inside a React, Vue, Svelte, Solid or Angular app rather than a third party iframe, and it is built for front end and product teams who need policy text and cookie consent to stay in sync with the code they actually ship.
