Knack

Knack is a no-code platform for building custom online databases and applications, aligning well with the core concept of a low-code/no-code internal tools platform. It explicitly offers features like drag-and-drop UI building, integrations with various data sources and APIs, workflow automation, and robust security features including access control. While it doesn't explicitly mention code customization in the same way Retool does (embedding JS/SQL), it focuses on no-code solutions. It also offers flexible deployment options (cloud/on-premise) and AI-powered app building, which aligns with AI/LLM integration. The platform is designed for building internal tools and portals, fitting the target audience and use cases.
