MUI Toolpad

MUI Toolpad is a low-code builder for dashboards and internal apps, offering both a studio version (now deprecated in favor of Core) and a Core version with React components. It allows developers to create internal applications faster using pre-built UI components and data source connections. Toolpad Core provides full-stack React components for building responsive dashboards and internal tools.

MUI Toolpad (both Studio and Core) aligns well with the description of Retool as a low-code platform for building internal applications. The website content highlights features like drag-and-drop UI building, database integrations, and code customization. It also emphasizes the use of React components, security features, and deployment options, matching several of the 'must-have' and 'other' features listed for Retool.
