Ninetailed

Ninetailed is a personalization service for websites and apps. Its SDK repository holds the open-source plugins and SDKs for JavaScript, Node.js, React and Next.js that connect a site to the service.

Worth knowing

The product’s own site and docs now redirect to Contentful pages, and the record names Contentful as its parent. Whether Ninetailed is still sold as a separate product could not be confirmed from a readable page, so the record stays a stub.
