Stackwyn started as a personal tool for visualising database schemas and API layers before writing a single line of code. It grew into a full-stack design surface — one canvas for every layer of a modern backend.
Most design tools are built for designers. Most database tools are built for DBAs. Stackwyn is built for fullstack developers who want to think through a system — tables, endpoints, auth, jobs, storage — before touching their editor.
The goal is simple: one visual workspace that connects to your real stack. Not just a diagram tool. Not just a DB client. Something that bridges the gap between planning and running code.
Canvas data isn't locked in a proprietary format — it exports to SQL, Prisma, OpenAPI, and React. Your design is always one click away from being real code.
Every node that can connect to a real system, does. You can test a DB connection, push a table, fire an API request, or run a cron job — from the same canvas where you designed it.
The core tool is free. No trial limits, no feature gates behind a paywall that makes the app useless. Premium features exist but the product is genuinely useful without them.
Database credentials never leave your machine. The Express backend runs locally inside the Electron app. Cloud save is opt-in and only stores your canvas layout — never your secrets.
Stackwyn should save you time, not add ceremony. The canvas is fast, exports are one click, and the AI assistant can scaffold a multi-table schema in seconds.
