I need suggestions about Frameworks or SaaS that help me to collect user-entered data about usability and user experience.
For example, a framework that could accelerate the development of a REST or GraphQL API that collects opinions or Likert-like data. Or a SaaS that exposes REST or GraphQL API for collect that kind of data, letting me configure what data I want to collect in each end-point, in the case of a REST API.
In the front-end, the developer could just design its own form based on the data that the API receive and send the data to the implemented service. In the back, I imagine the Framework or SaaS could be interpreted as a microservice, in which I could access and manipulate the data the way I want.
