Woopra, the impressive live tracking and analytics service, today announced that they are opening their doors for all new signups. Until today, new users had to be approved if they didn’t have an invite code.

Sure, there are a lot of analytics alternatives, so what makes Woopra so special? Real Time. It’s the big trend this year, and Woopra certainly delivers. Woopra is similar to Google Analytics but provides real time stats and a number of additional features, such as the ability to chat real time with visitors to the site. (See also, Chartbeat and our coverage).

Woopra first became public when Cali Lewis of GeekBrief.TV spoke with John Pozadzides, CEO of iFusion Labs, the parent company of Woopra at WordCamp Dallas in September 2008.

With today’s public launch of Woopra, one of the biggest changes is the pricing. Until now, Woopra has been free for all users. Coming with the public launch is paid accounts. All current users are getting moved to the free account (pageviews limit: 250,000), with an option to upgrade to a premium account. Also, Woopra is supporting SSL, making SSL available to all paying clients. One of the big requests that users have requested is that Woopra support subdomains as well, and this is also being announced. You can find the full list of plans for Woopra here.

The default mode for Google Analytics and other Website tracking software often makes you wait an entire day to find out what is happening on your site. There is a 24-hour delay (although this can often be changed in settings). Speed up the feedback loop, and Websites in theory could become even more responsive to traffic and attention peaks or to unexpected sluggishness. Betaworks, John Borthwick’s startup holding company which has stakes in Twitter and Tweetdeck, and spun off bit.ly, has just launched Chartbeat.

Keeping with Betaworks’ focus on real-time data services, Chartbeat offers a dashboard for Website owners that monitors how many people are on their site at any given second, where they are coming from, which pages visitors are looking at the most, as well as conversations and links from Twitter. It also shows average load times, what percentage of current visitors are returning, how many are reading, how many are actively writing in comments or engaging with the site in some other way, and how many are simply idle. Webmasters can set up alerts for traffic peaks and site slowdowns. All it requires is one line of Javascript to be inserted on a site and then it pings Chartbeat every 10 seconds.

The dashboard also offers a historical view, and even lets you play the dashboard through time like a movie so that you can see for instance what was going on during a particular peak—where was traffic coming from and what were visitors looking at. If you choose, you can also share your dashboard and make it public. Venture capitalist Fred Wilson has done so for his blog A VC. Click through to his blog, and then you can see the results on his Chartbeat here. The video below also shows what it looks like.

Chartbeat is offering a free 30-day trial and then wants to charge $10 a month for the service. Competing real-time Web analytics services include Get Clicky and Woopra (which we covered here).

Want to talk to the people visiting your blog in real time via a chat request? That’s just one of the features of new stats/analytics startup Woopra. Think Google Analytics or Nuconomy, but in real time.

The product includes real time statistics (”tiny details on every single visit and/or visitor, where they came from, what pages they visited what keywords they used etc.”), chatting with users on the site at any time (and tagging them for future identification). Cali Lewis interviewed the founder at Wordcamp Dallas today. The video demo is below (and is significantly better than the officially-worst-demo-video-ever produced by the company).

Woopra is currently in private beta and will only take blogs with less than 10,000 page views/day. Like Google analytics and most other hosted analytics services, integration occurs via a javascript addition to the sites you want to track. The evolution of analytics condinues (I still remember the days of MeasureMap, which was awesome when it actually worked).
