Why not embed a Lua interpreter? Or maybe a Wren [1] interpreter for something different? I don't understand why they developed a language and VM from scratch. And I thought I over-engineered my projects. The time spent developing and maintaining that could be directed to something more directly related to your product.

"JSON based executable file format"

My brain had a core dump when i've read that...

One of the problems with how we develop software today is the long path from idea to a working prototype. There are many layers in between, each with its own set of abstractions and assumptions. Factor in the number of different platforms you need to develop for, and you've got yourself a very complex world you need to navigate.

Writing software in 2016 is to some extent similar to operating a 18th century ship through the dangerous waters. We have a good enough machine to take us places, but we still need to visit the engine room, to keep things running. It's getting better nonetheless, but you still need a specialized crew to steer a big ship in the right direction. I would much rather prefer a yacht, where I could just press a button and enjoy a more experimental, higher level experience, in which my job would be to map ideas to real world working systems.

With that given said, this definitely looks interesting. I'll surely give it a try.

I am going to use this to teach the basis of mobile programming to my wife and some friend s- I promised them that the day I had access to a simple IDE for developing apps I would spend a weekend telling them about the concepts of development. I already managed to teach my wife about the thinking behind UI and wireframing design thanks to Sketch.

Can't wait for this upcoming weekend to get them started, food & code is awaiting!

I downloaded the beta and tried it out. The concept is interesting, but the execution is still uneven (understandably so, considering that this is a beta). The way that the mobile app UI is rendered on the desktop is pretty bad, especially the lack of antialiasing on the fonts.

It has that uncanny valley feel that you'd expect when somebody reimplements a UI toolkit and tries to mimic the look and feel. I'd really like to know if it looks better and more native on a device.

There are also bits and pieces that don't seem to work as expected. Like, I'm having trouble getting the built in HTTP client to actually successfully complete a request.

The design tool is slick though, so I'm looking forward to seeing where they take it. It could be pretty compelling for rapid prototyping.

They have more video demos here: http://blog.creolabs.com

Congrats on shipping the beta! It looks like a well thought out prototype/simple app creator. Can u give any idea on pricing?

I feel like the "run any iOS code on Mac" part of this is being overlooked. Doesn't that mean you guys (@creolabs) re-implemented UIKit on top of AppKit, a la Chameleon? If so... that's HUGE in and of itself.

This reminds me a lot of Visual Studio during the ASP.NET webforms era. The tool looks really cool and as a non-iOS dev this would really help me get a prototype up quickly. Kudos to the team for a great product.

Older thread about Creo's tryst with YC Application [1] - shows a lot of struggle and the fruits of their labor in todays beta release. Great Job guys!

Is possible to drive the code with swift instead of the custom language?

Reminds of an early version of Visual Basic. Not saying that in a bad way either. For the original release VB enabled a huge number of GUI applications to be built quickly.

It would be so good to be able to use just one language (swift, scala, or java preferably) to write portable but the native UI.

however, what happens when I have written my app & this company goes belly up. It isn't open source so I guess then I'd be sol.

for now I use j2objc & it is working pretty well. My only big wish would be for some way to write persistence logic just once too.

I like the idea of building apps in a drag-and-drop ui-builders for prototyping. But I can't imaging using this for real products other than maybe a static app. How do you even connect to an existing backend? The 'demo' video suggests connecting directly to a database... So much for security.

I hope these guys realize that Creo is very popular CAD tool. Maybe they should rename their product.

This seems pretty cool. It gave me a Android App inventor vibe. My question is how much flexibility do get. Because drag and drop UI/App builders constrain you into a design philosophy that's hard to change.

All this to say, I wasn't convinced.

Looks promising. I am a Swift fan so I guess I am not going to change, but I love that people are creating other options that can appeal to more people. It looks like these guys have a number of good ideas.

No Linux or Windows support?

Can you make WebApps?
