Skyve

Skyve is an open-source low-code platform that aligns well with the concept of Retool. It explicitly mentions features like a point-and-click builder (drag-and-drop UI), the ability to branch out into 'traditional' development with a high-level API (code customization), support for various database types and integrations, enterprise-grade security with role-based access control, and flexible deployment options (on-premise or in the cloud). It also highlights workflow automation, mobile responsiveness, and prebuilt components. The platform's focus on rapid development of internal tools and enterprise applications further strengthens the match.
