Oracle APEX

Oracle APEX is a low-code application development platform that enables developers to build and deploy enterprise-ready, AI-powered applications. It provides a visual development interface, pre-built components, and extensive connectors to various data sources and applications. The platform emphasizes rapid development, enterprise readiness, and powerful data visualization, leveraging Oracle Database capabilities and AI integration.

Oracle APEX is a low-code application development platform that aligns very closely with Retool's core offering. It provides a browser-based, intuitive graphical interface for building applications, supports integration with various data sources including Oracle Database and REST interfaces, and allows for code customization (e.g., SQL statements, JavaScript). It also emphasizes security features, flexible deployment options within the Oracle Cloud, and includes AI-assisted development tools. The platform offers prebuilt components and templates, and supports mobile responsiveness and custom theming. While not explicitly stated as 'drag-and-drop UI builder' in the exact phrasing, the description 'rich, browser-based, intuitive graphical interface' and 'powerful UI components' strongly imply a visual builder. The 'partner & customer portals' feature is also covered by the ability to build 'Public SaaS and ISV apps' and 'secure, white-labeled portals for vendors, contractors, or customers'.
