Hi HN, OP here.I built this because I was frustrated with the current state of DB design tools. They are usually either heavy enterprise desktop apps (like DataGrip/Workbench) or simple drawing tools that don't export usable code.I wanted a "VS Code-like" experience in the browser: dark mode, strict typing, and instant visual feedback.The tech stack is quite aggressive: - Frontend: Angular 21 (Latest). I'm using Signals exclusively for the graph state management to handle 100+ nodes without layout thrashing. - Backend: .NET 10 for DDL generation and schema validation.Current features: - Visual Table/Column editor. - Drag & drop relationships (1:N handling). - Exports to PostgreSQL DDL and Entity Framework Core.It's an MVP, so I'm looking for feedback on the graph interaction and the UI feel.Does the "IDE-like" layout work for you for this kind of task?
