Design
Click anything. Change anything.
Select an element on the canvas and it lights up in the layer tree. Drag it, resize it, nest it, duplicate it. It works the way you already work.

How it works
Four things, and you've shipped a site
Style
A style panel you already know
Layout, spacing, type, fills, borders and effects — with classes and states where you expect them, and live spacing readouts as you drag.
Responsive
Every screen, side by side
Design desktop, tablet and phone on one canvas instead of switching between them. Drag the frame to any width and watch the layout answer.
Publish
Ship it without a developer
Review what changed in plain language, then publish straight to GitHub. Your site goes live on whatever host you already use.

Features
Everything you need to design a real site
The tools you already reach for, plus the ones you usually have to ask someone else for.
Changes appear instantly
No save button, no reload, no waiting. Edits appear on the canvas as you make them — and your scroll position stays exactly where it was.
Style panel, not a stylesheet
Everything you'd expect, where you'd expect it. Classes and states included.
Components with real settings
Drop in a component and fill in its options with proper controls — no guessing.
A CMS that's already there
Edit collections, add fields, and bind any of them to what's on the canvas.
Your design tokens, visible
Colors, type scales and spacing laid out as tables — with contrast checked for you.
Responsive by default
Three breakpoints on one canvas, or drag the frame to any width you like.
Publishing without the terminal
Branches, changes and publishing, explained in plain language.
No lock-in
The site is yours the whole time
Stacki edits real files in a folder on your computer. There's no account, no hosting plan, and no export step — because there's nothing to export from. Close the app and your site is still just there.
- Runs on your machine, offline
- Publishes to any host you like
- Clean code a developer can pick up
- MIT licensed, forever free
Your files. Your machine. Your hosting. Your call.
