One redesign away from perfect.
Design on a canvas, get production code with your exact layout and the behaviour to match: fields that grow, screens that scroll, buttons that navigate. On all four platforms.
No account needed to try it.
Fidelity
What you draw is what ships.
Most tools read a design file and work out what you probably meant. There is nothing to work out here. The numbers you set on the canvas are the numbers in the code: same position, same size, every time.
One design. Four platforms.

Everything on the canvas
What you can build
Real screens, not wireframes. Everything below reaches your exported code.
- Shapes with the details kept. Rectangles with a radius per corner, plus regular polygons and stars exported as real vector shapes rather than approximations.
- Type with the details intact. Font, weight, italic, underline, alignment, and the two that always drift in generated code: line height and letter spacing.
- Gradients at the angle you set. On every export, the angle you chose is the angle in the code, not snapped to a diagonal.
- Buttons that do something. Link one screen to another, or call a function your codebase already has, and the generated code wires it up.
- Text inputs that behave. Placeholders, password fields, and the right keyboard for emails, numbers, phone numbers and URLs.
- Fields that grow as you type. A multiline field expands and pushes everything below it down, on all four platforms. The hardest thing we build, and the fastest way to test whether generated code really matches a design.
- Screens that scroll properly. Including to the true bottom after a field has grown past the edge of the device.
- Images, shadows, borders, rotation, opacity. The finishing layer, with the per-target details written down rather than left for you to discover.
How does it work?
Design on the canvas.
Lay out your screen the way you want it to ship. The canvas is the spec, not a sketch of one.
Pick your platforms.
React Native, HTML/CSS, SwiftUI, Flutter. Choose one or all four.
Get the code.
Real source code, in a file you own, ready to drop straight into your project.
Proof, not promises
We're not asking you to take our word for it.
Every claim on this page is something you can check. Here is the same card, drawn once on the canvas, in all four exports.
On the canvasA card at x 24, y 112, 220 by 96, corner radius 16.
- React Native
left: 24, top: 112, width: 220, height: 96 - Flutter
Positioned(left: 24, top: 112), width: 220, height: 96 - HTML and CSS
left: 24px; top: 112px; width: 220px; height: 96px - SwiftUI
.frame(width: 220, height: 96).position(x: 134, y: 160)
Three of them carry your numbers literally. SwiftUI reads 134 and 160 because SwiftUI positions views by their centre, not their top-left corner: 24 plus half of 220, 112 plus half of 96. Same rectangle, written the way each language expects it. Getting that right on every element, in four languages, is the entire product.
How we keep ourselves honest
- Generated SwiftUI is type-checked against the real iOS SDK. swiftc -typecheck, run by a dedicated script against the real compiler rather than by hand.
- Generated Flutter is built, not just analysed. It passes flutter analyze and flutter build web against the real SDK, run by that same script.
- Every code sample on this site is byte-compared against the generator. A sample cannot drift from what you would actually get.
- Our build fails if the marketing claims the output is responsive. It is not, deliberately, and we wrote that claim down once by mistake.
Anyone can write a sentence. The last two here fail our build if they stop being true; the first two run against the real Xcode and Flutter toolchains, which the build cannot install for itself.
The benchmark, when it is ready. We're running the same design through every tool on the market, ours included, and publishing the scoring method before the results so we cannot adjust it afterwards to suit us. Read the methodology
Why isn't this a Figma plugin?
Because a plugin can only guess. It reads a file it did not create, infers structure from layer names, and hands you its best interpretation. We built the canvas so there is nothing to infer. You are not fighting a file format, and you are not limited to whatever the web can render.
