Show HN: Visual Database Schema Designer (Angular 21 and .NET 10)
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?

- QuiCasseRien 9mo agovery nice ! Does there is a setting to show the description in the canvas ? The idea is to print the whole schema, included description. Thanks
- temakonkin 9mo agoof course, each object (instance, database, schemas, tables, columns) has a "description" field. If you add it, then when you hold the cursor over the object for a second, the description type will be displayed (this is useful if you need to document the database).
