Hello all you good people on Product Hunt! I'm Kristian and I'm building Decise.

Decise is a macOS-native visual editor for Next.js / React / Tailwind web apps and marketing websites built using the same stack.

You open your real local web app inside Decise, click and modify the rendered UI components, and edits get written back to source. Minimal diffs. No Figma round-trip, no "AI guess what file this came from," no parallel design system that drifts from prod. The thing on screen is the thing in your codebase.

Why I'm building it: scratching a personal itch. I do both design and dev, and the ping-pong between them was getting crazy. I can see exactly what's wrong with a component... so why can't I just visually fix it? That's especially painful in codebases I didn't fully write myself, and AI tools have only made it worse: you spot the problem instantly, then spend the next ten minutes hunting for the file, tweaking classes, losing all the visual context you had a second ago. Tedious. Decise collapses that loop.

What's working today: direct manipulation of components, source-backed token edits across the design system, a route-first project navigator, and more... with new features landing constantly. Check out the work-in-progress website for more details: https://www.decise.app.

What I'd love from this community: brutal feedback, especially from people who've tried (and bounced off) visual editors before. Tell me where the seams show. Tell me what would make your life easier.

Happy to be here.
