Don’t Just Design – Make It Real
Imagine your designs feel like the final product: shiny, responsive and fully interactive. All done in one tool.

Going Truly Responsive Instead of Fake Flexible
Stop pushing pixels to align layouts. Responsiveness to end discussions before they start.
Pixel perfect, without dragging.
No more fake‑flexible layouts that should work. Yet they never do. It’s time for truly flexible layouts that adapt & align. You set the rules, they obey.
Breakpoints.
Not breaking designs.
Ever had 3 screens for the same thing to show it on different devices? Yeah. Stop that.
1 change equals 50 right decisions.
Save your time & nerves: Sync changes to elements, colors, layouts. And still set some properties like texts individually in each instance.
On Being Dr. Frankenstein
Making your prototype come to life with interaction & animation.
Highest fidelity, non‑negotiable.
Prototype any way you want. As interactive as you want it to be.
{artboard-chaos: none;}
No more 10+ nearly identical art boards to produce even small interactions.
Set: State, Trigger, Action. Go.
Going micro.
Or full size & all‑in.
No matter if it's a micro‑animation to boost awareness. Or a full page dynamic interaction that changes everything. All done in Antetype.
Design Beyond Yourself
Getting your prototype out into the wild. To prove how good it works.
You design it. We host it.
Everyone needs to host their prototype. But no one wants to think too much about the technical details needed. We'll take care of it. You just upload & share it to anyone you want.
Use it. Test it.
Break it. Fix it.
User testing is as easy as sending your Antetype link and getting feedback: Your prototype runs on any device with a browser. 100 % open web technology.

Stop the back and forth: All details included.
Your prototype comes with information for developers to implement it – without any extra work for you. All necessary specifications for elements, used colors, names and widgets. Out of the box, into the div.
Pro Features, For Free.
Complex projects require advanced features. All included. For you.
-
Dynamic Content
Lorem ipsum! dolor sit amet! consetetur sadipscing elitr! Yeah, no. Fill elements dynamically with live data.
-
External libraries
Some built libraries for nice graphs. Others for fancy 3d animations. You get them for free. Now you may use them in your prototyping game.
-
Interactive input fields
"You would be able to type here.“ No. We won’t have that. Test interactive inputs as interactive as the real deal. React to the real inputs, dynamically.
-
Advanced layouts
Layouts are set by behaviour, not absolute values. Add custom breakpoints and you may build the most complex layouts ever – if your project requires them.
-
Set individual or shared
Widgets sync any update you make to every instance. Some things should stay individual, like text or color? Widgets' individual & shared properties let you do that.
-
Unlimited files & sizes
Prototypes should never be restricted by arbitrary limits. No file’s too big, no artboards too many for Antetype. Unlimited prototyping to conquer complexity.
-
Native scrolling
Have you heard how some prototyping tools hack scroll bars into themselves? Sends shivers down my spine. We rely on native scrolling. Why? Because it works every time. Feels real, simply because it is.
-
Native macOS performance
Web apps lag. And they require you to be connected sometimes. Let’s go full speed wherever you work best. Designing on top of Mt. Everest with peak performance? Yep, entirely possible.
-
Fully customizable
Used by millions worldwide: Your prototype is pure HTML, CSS and JavaScript. Do literally anything you do online. And when in doubt, just ask the Internet. The web (and StackOverflow) shall answer your prayers.
Built for designers that make things better, easier & more fun.
Feels different at first, is better at last.
Seeing your flexible layout adapt isn’t just fun to look at. Helps you iterate faster and change things quickly.
No longer will you harass pixels individually: Designing will feel different. And it will be faster quickly.
As interactive as the real thing.
The world isn’t static. Why should your prototype be? Every interaction you need – without switching apps.
Powerful custom states if you need them. Easy animations without them.
Always fun, even under pressure.
Made for UX professionals, especially in highly complex projects.
No more lagging web apps you need to wait for: Native macOS for maximum performance.
Build prototypes so realistic & responsive, stakeholders didn’t consider them possible.
