Boomi (by Dell Technologies)

Boomi is a strong match for the Retool concept. It is an Integration Platform as a Service (iPaaS) that focuses on connecting applications, data, and automating workflows, which aligns well with the core value proposition of Retool. Boomi explicitly mentions API and database integrations, low-code capabilities for building user experiences (though not a drag-and-drop UI builder for internal tools specifically), code customization through its integration platform, and robust security features. It also offers flexible deployment options and strong workflow automation. While it doesn't explicitly state a 'drag-and-drop UI builder' for internal tools, its 'Flow' product is described as building user experiences with low-code, which is a close equivalent for the purpose of building internal applications. The platform also heavily emphasizes AI integration and agent management, which aligns with the AI features of the concept.
