Hey guys, here are the lastest StackVM news. So we applied to Y Combinator for the Winter 2011 funding cycle but got rejected. On November 2 we got an email saying that they could not accept our application for funding, which meant that we wouldn't even get the interview. Our plan was to surprise Y Combinator folks at the interview by launching a private beta version of our software one day before the interview so that at the time we got interviewed the story was on the Hacker News front page. Well, now we can't surprise them this way, but we can surprise everyone else by saying that we are launching public beta!

Our first product is built on top of StackVM and is called Browserling. It's an interactive cross-browser testing tool inside of your browser. A real browser inside of your browser! Just go to browserling.com to try it out! (please use Chrome.)

In case there is a long queue of people willing to try Browserling, we also made a short video that shows what it is and how it works:

Browserling is a freemium based product. If you register, you get 5 mins for free for as many times as you wish (but you have to wait in the queue again with everyone else). If you don't register, it's just 1min 30secs for as many times as you wish. We haven't figured out the paid plans yet, but we'll get there shortly.

As Browserling is beta, we currently provide Internet Explorer versions 5.5, 6, 7, 8, and 9, (version 5.5, 6, 7, 8 via IETester, and version 9 is native IE), Chrome, Firefox, Safari and Opera.

Browserling is also just the first of many projects that we'll be launching. The next one is going to bring arbitrary desktop applications to the web, and then we have a whole bunch more planned. All these projects will be based on the StackVM technology!

If you're interested in how all of this develops, please subscribe to my blog and follow me on Twitter!

Also, if you use IRC, join #stackvm channel on irc.freenode.net and have fun with us!

In fact, that it isn't as painfully obvious to YC as it is to me is all the evidence anyone with any startup experience needs that YC is run by people who lucked into money, not people who know how to do startups. (Yeah, they had a startup sell at the time when everything was getting bought that wasn't nailed down.)

Wow, really figures that Y combinator wouldn't even bring you guys in for an interview. I've been keeping up with you're work these past several months and continually impressed. I've been doing startups for 20 years... I know good founders when I see them.

I think Y combinator is a bunch of douchebags who will try to feed you into the Silicon Valley startup mill, which really isn't a good place for launching startups, despite what they'd have you believe. Unfortunately, for people who haven't been in a bunch of startups they don't have the experience to know that the lines being fed are BS. It's like investors turning their money over to people running mutual funds, they forget that those running mutual funds make money by getting people to turn over their money to them... same thing with YC, only its equity and trust they exploit.

You guys will succeed if you keep at it, it is guaranteed. It does take some talent, and some luck, but really not much, and you've got the perspective to make your own luck and the talent to make valuable products.

Anyway-- best wishes.

Tried it, never got to see anything other than the loading page, which was interrupted by the time's up page. So I never got to see anything.

Not quite ready for prime time, I think?

November 24, 2010, 15:48

Not yet. This is beta. Now that we have launched we know exactly what the weak points are and we can work on those!

Launch and then iterate is how we do things. Launch even if it's broken!

November 24, 2010, 03:36

Neat idea, but your presentation of it sucks. Terrible audio with a bad logo, no wonder people wont take you seriously. Presentation is everything, and when you look like you are a bunch of peope using wordard and a mic from their nokia that is probably how people are going to view the rest of the stuff you make.

November 24, 2010, 15:55

Why so serious?

Sweet, I could definitely use a service like this. There are a few out there but last time I looked none seemed a good enough fit for me to buy. I'm cheap and only need it occasionally but I would pay something if it was easy/simple and priced right.

November 24, 2010, 15:56

Awesome. We'll have some cheap plan for sure after we put multiple users on a single windows instane. Also any ideas how much you'd be able to afford for the service?

No chance to try it. The only thing people can see is a combination of loading screens.

November 24, 2010, 15:57

We had some technical troubles. Try now.

Fake. I've read the throughout javascript code and there is no mechanism to view/connect to a virtual machine.

November 24, 2010, 15:58

I can tell that from the pixels, why read the source code?

November 24, 2010, 10:29

It doesn't work...

November 24, 2010, 15:58

Hi, try now, we had major trouble when thousands of people started hitting the servers when we launched!

November 24, 2010, 16:27

Thanks, it is working now. Everyone having trouble consider creating an account, cause it is a lot faster than guest mode.

Very cool stuff! I've always thought this would make a great service. Look forward to testing it out.

November 24, 2010, 16:55

Checked it out, a big suggestion I have is to be able to set the resolution of the frame/window your site is rendered within.

I only got 1:30 preview as well.

I tried going to http://www.stockchase.com which is a text only website dealing with the stock market.
After waiting in queue for a minute or two, I was shown a blank screen with a count down in the corner. Assuming the countdown was letting me know how the processing was going I waited until it reached 0. At which point it said that time was up.

Tried a secondtime, and it timed out before showing me the blank screen.

I thought browing a text website would be really easy.

Same here... I waited quite a bit, and was trying to go to http://blackfriday.com

When it was my turn I got a waiting "robot" screen then blank grey screen. I tried changing using different browsers, but it was really unresponsive to my clicks. My time was up after tying to try three browsers (safari, opera, ie8) and I had only seen a big grey box for each.

I hope you guys can resolve your issues because it looks like this would be extremely useful.

December 02, 2010, 09:26

Yes this was the issue I had to.

November 28, 2010, 12:34

Firstly it doesn't go to the URL i want to. It loads some pages someone loaded before. Secondly the comment box got overshadowed by the browserling's screen.

December 02, 2010, 03:19

I know I'm late to the party here, but you have made something really, REALLY cool here Peteris! Love. It.

December 02, 2010, 09:25

Can't get it to work. Tried it in Firefox 3.6 and got stuck on "Loading" Chrome 7 doesn't render anything

Wow! This is just awesome... Only a dev who uses Mac knows how hard it is to get IE running on it. Revolutionary idea. Can't believe YC rejected you guys. Dunno about the rest... but i love the logo :P Keep up the good work. I just have one issue to raise... I can kinda override the 5min limit by pressing the "go" button seconds before it expires. Just so you can fix that bug. :)

browserling is incredibly awesome. It is now 100% stable from my current usage.

I was showing our QA guys this product at my company and then showed them the work that was going on with Testling,

and they all said "This is the future of testing!! forget selenium!"

Definitely a must have for QA specialists!

Good luck with Browserling. I use BrowserStack from time-to-time and find that they offer a good service at a decent price.

I tried it with one of my own sites that I have already tested on Browerstack. Browserling looks less polished, very slow and works less smoothly, at the moment but that is understandable given that it is still in beta. I am curious to see how it all develops.

Your posts are so informative that I always come back for more.
