Optimize vs Reindex: What are the differences?

Optimize: A/B testing and personalization platform. Whether it’s a custom-tailored message at checkout or a completely revamped homepage,it shows you which site experiences engage and delight your customers, and gives you the solutions you need to deliver them; Reindex: GraphQL backend as a service for React and React Native apps. Reindex makes it easy to set up a GraphQL backend that stores the data for your application, handles security with user authentication and permissions, and is easy to extend with webhooks. You can focus on building an awesome app for your users.

Optimize belongs to "A/B Testing Analytics" category of the tech stack, while Reindex can be primarily classified under "Platform as a Service".
