About Decise
Made by Kristian — designer, developer, maker
I’m a coder who designs and a designer who codes. I’ve shipped multiple SaaS products over the years and I’ve always hated the artificial divide between design and development. Figma over here, your IDE of choice over there, browser dev tools in between, and awkward conversations about what really matters. Every context switch breaks your flow. Yet we are making a product that needs to come together, for the user.
When AI tools started generating entire apps, this gap got worse, not better. I could scaffold a full Next.js app in minutes, then spend hours reading code I did not write to move buttons twenty pixels to the right.
I also did not want a fake visual editor that looked magical right up until it broke your code. If a refactor is safe, Decise should do it. If it needs a fallback or should block, it should tell you the truth.
So I built Decise. Because your codebase is already a design tool. It just needed to become visual.
Philosophy
Code is the source of truth. Decise never creates an intermediate format, a proprietary layer, or a shadow copy of your project. Every edit writes directly to your .tsx files with minimal, clean diffs.
Layout and styling only. Decise modifies visual properties — Tailwind classes, element positioning, component structure. It never touches event handlers, state management, data fetching, or business logic.
Native because it matters. Decise is built in Swift for macOS. Not because native is trendy, but because a visual editor needs to feel instant. Dragging an element should feel like dragging an element — not like dragging a web page pretending to be an element.
