You can build low-code tools with Refine though. One of my side projects Jinjat (https://jinjat.com) uses Refine as the UI framework to render the data models that you have in your dbt project, as an example. Retool is an end-to-end tool whereas Refine focuses on the front-end and gives the flexibility in the backend for your business logic, which is often hard to scale out with Retool.
