Overview

Database Designer is a standalone desktop application that lets you visually design PostgreSQL databases without writing a single line of code. Drag‑and‑drop tables, define columns, relationships, indexes, and more – then instantly generate:

Complete, ready‑to‑run SQL scripts (schemas, tables, foreign keys, indexes)
Clean Markdown documentation for your schema
Entity Framework‑compatible C# model classes

Everything runs 100 % locally and offline, with built‑in post‑quantum‑resistant encryption for project files via Pariah Cybersecurity v2.

Features

One‑click exports to PostgreSQL DDL, Markdown docs, and EF Core‑ready C# POCOs
Fully offline operation – no internet required, ideal for secure or air‑gapped environments
Post‑quantum security using NIST‑approved algorithms (Kyber/CRYSTALS, AES‑256) for encrypted local project storage
Built‑in templates for common patterns (users/auth, e‑commerce, etc.)
Lightweight and performant – runs smoothly even on modest hardware (e.g., school laptops)

Live Product Page / Download

Steam (Early Access) – Download on Steam

No login is required; download and start designing immediately.

Demo

A quick 1‑minute demo showcases the intuitive interface, schema creation, relationship building, and one‑click exports to SQL, documentation, and C# models.

Origin

Database Designer started as an internal tool at Walker Industries to rapidly prototype and connect databases across ambitious projects such as:

XRUIOS – an XR‑focused shell OS
Project Replicant – local high‑functionality AI

Manually writing SQL, updating docs, and generating models was consuming hours better spent on innovation. The goal was to create a tool that felt joyful to use—fast, local, secure, and powerful enough for real production work.

What Makes It Special

Full offline execution with zero cloud lock‑in (cloud sync coming soon)
Post‑quantum encryption for future‑proof security
Table/project templates for consistency across teams
Planned open‑source release with a free SDK on the horizon

Tech Stack

C# / .NET for core logic and cross‑platform potential
Custom UI framework for a smooth, responsive drag‑and‑drop canvas
Pariah Cybersecurity v2 (open‑source library by Walker Industries) integrating post‑quantum algorithms
One‑click exporters for PostgreSQL DDL, Markdown docs, and EF Core‑ready C# POCOs

Unique Aspects

Fully local execution – perfect for secure or air‑gapped environments
Built‑in templates for common database patterns
Future‑proof encryption against quantum threats
Lightweight performance – runs well on modest hardware

Current Status

Built over 2025 with a focus on usability; the current version has some rough edges (messy code, minor bugs) but is actively improving.
