Is the HTML5 savior or full of BS? - rant warning

Can't decide any more. Their (very nice) demos (linked below) caught my eye from TechCrunch Disrupt, promising a JavaScript engine that solves all your HTML5 performance woes so I signed up for their newsletter. Yesterday they published their first one ( to give more information on the technology.

And while I was initially curious - I am actually pretty skeptical now. The thing is their product is supposedly aimed at developers but their wording is beyond vague. And I believe thats a wrong way to talk to developers.

You don't really know any more if they're bringing out something that's supposed to run in the browser or yet another JavaScript-to-native component based translator service or what...

Lets pull some quotes out of TechCrunch shall we?
Developers can code for in JavaScript. It’s as simple as that. Because the technology speaks directly to the GPU, it works on any device: iOS, Android, web, gaming consoles, and anything else with a GPU. The idea is that will let developers use its engine to create 3D templates, but there’s one condition. The templates have to be open-source, so that everyone can build off of them and enjoy them

Whole lot of hip words in there - not only devices, web, consoles but open-source too :) The Holy Grail indeed. And solving it all by letting JavaScript talk directly to the GPU you don't say :)

So after reading their newsletter and spotting the comparison with Twitter Bootstrap in there and that enables web developers to build APPS) here is my take on what they're doing:

⚫ the wording sounds like they'll let you write JavaScript-based apps but publish it as native (with or without a wrapper)... JS-talking-directly-to-GPU would be WebGL - so this might be why they're changing the wording to apps instead of websites... because WebGL has been available on iOS since 4.2 version, just not activated in mobile Safari... to enable it you'd need to have a custom tweaked version of the webview container ( - hence native and apps story... basically there are like at least 3 other companies doing that (AppMobi's directCanvas, CocoonJS or ImpactJS

⚫ possibly at the same time also offering something for the web i.e. yet another optimized jQuery clone that tries to H/W accelerate everything 

So while competition is always a good thing and I hope that brings something amazing to the market - its the condescending wording (saying basically nothing) that set me off on this rant :) Fancy wording is part of the startup game, but still...

Stuff like this:
App layouts, animations and designs that were only possible in native apps are now within the reach of all web developers.  We hope our accomplishment unleashes a wave a web app development like we've never seen before

Because I do have a bit of experience in the mobile HTML5 dev and its difficult to imagine that so so many developers could have missed something to crucial performance-wise before... I can only hope there is something that we could be doing better - but I don't think so... you could of course never do enough optimizations... 

Anyway if you need a mobile browser-based incredible performance JS engine to be impressed about try Sprite3D ( or of course +three.js ( for the WebGL stuff (at the moment almost desktop only - with a few exceptions).

I'm probably even more skeptical about it all, simply because TechCrunch are rather good at making everything seem groundbreaking. We'll see when it's released I guess
Yeah exactly - its like every little app is a startup now. Its soo cool to have your own startup that its almost a hype - and a lot of early demos or communiqués are sometimes just embarrassing to watch. You read about them on TechCrunch once, only to never be heard from again...
have you changed your mind in any way since this post?
God no. Like I said they make nice demos (but with a few months to spare and 5 mil. $$$ in the bank - who wouldn't) but when I hear that they're focusing on a physics engine with a vision to some day replace jQuery - I don't know if I want to laugh or cry.

I love playing with animation in UIs and the demos do speak to me - but lets face it they don't work properly/without-glitches even in some desktop browsers. Forget about mobile - I've tested on an iPhone, iPad and Android - when it works - smooth it is not.

The things is the logic behind what they're doing is flawed and limited in scope. Desktop is usually easy - you throw anything in there and there is enough memory/cpu/gpu for everything - but its not going to work on mobile. Especially the demos that display graphics/images beyond a few simple elements - strategies like loading it all on the GPU and then using translated/matrixes to tweek the properties without triggering layout/parse can only get you so far. Its gets slow and the device struggles/flickers to do garbage collection anyway - a lightbox image gallery where you load all full screen images on the GPU is crap in the making.

And its not like they don't know it - just saw a video introducing these demos and the conclusion was that they'll be adding a webgl renderer into the mix in the near future. So just like I said, we're getting back to them being a threeJS competitor - possibly just with a focus on 2d/apps/interfaces which could still be pretty cool. If they ever manage to put their foot where their mouth is :)
