XRebel 1.0 – The Interactive Java Profiler

Hi folks. Jevgeni here, your friendly neighborhood startup founder and CEO.

Today we proudly announce the general availability of XRebel 1.0. XRebel was born over a year ago, in a brainstorm that I had with my co-founder Toomas Römer at a particularly boring conference session in Las Vegas. We spent a year researching, building and rebuilding to finally achieve the product that we are presenting now. We are extremely proud of the result – it incorporates feedback from hundreds of users and it started selling even before we officially launched it! How cool is that?

We call XRebel an “Interactive Profiler”. Unlike usual profilers that are meant to be used by performance experts in dedicated sessions, XRebel is meant to be used by everyone to prevent performance issues while code is being written. XRebel runs with your web application all the time, monitoring performance metrics and notifying you proactively when detecting an issue. It then displays an issue-focused view which lets you drill down into the problem and find the root cause right away.

In the first version, which we are announcing today, we focus on creating an amazing experience for discovering and fixing three key problems that were mentioned most often by our users: database issues, http session issues and hidden exceptions.

We are very thankful to over 500 of our active beta testers – their feedback made the final product significantly better. When asked if they liked the product, 97% said “Yes”. I’m still not sure what was wrong with the other 3% :)

Here are a few short quotes from them:

XRebel is unbelievably cool” said Veit Weber, ULC GmbH.
XRebel, take my money!” was tweeted by Federico Russo, Antea srl.
XRebel is my profile buddy!” said Howard Rafal of Broad Institute.

Here’s a longer one from Petri Tuomaala, CTO of Elbit Oy:

We found some very interesting side-effects right away. The worst of those was some badly coded Hibernate which would generate over 700 database queries on some pages. We also found some surprisingly slow SQL, which should not have been that slow. The JSF memory footprint was a bad surprise – some beans were in the session that shouldn’t have been there.

The handful of developers below were our most active beta testers. We’d like to extend them our personal gratitude and recognize their contribution to the success of our product!

  • Benno Markiewicz
  • Howard Rafal
  • Irina Ivanova
  • Kevin Davis
  • Markus Eisele
  • Polina Morozova
  • Roger F. Breakey

The list price will be $365 per seat per year, but for another month (until the 12th of July) the 60% Early Adopter discount is available, making the current price just $146. Hurry up to evaluate and buy XRebel at this price – it’s a bargain!

    Any ‘win a free license of xrebel’ contests coming up? Really enjoyed using the trial version.

    I see you are going with the same “per seat/per year” pricing for XRebel that you do for JRebel. Your pricing scheme is a scourge to developers because your software actually disables itself after a year. So you in effect extort money from developers every year. I understand if you want support and upgrades you need to pay every year, but if you are happy with the version you have I don’t understand why you can’t continue to use it even after the year is up.

    Zero Turnaround is the only software company I know of that disables their software if a developer doesn’t pay money every year, every other company simply stops support and upgrades but still let’s you use it.

    I really like JRebel and XRebel sounds very handy but until you fix your unfair licensing model I will be boycotting all Zero Turnaround products.

    It would be great if some ZT official could reply. Thanks.

    I’m sorry that you consider our licensing model unfair, but we believe that we create more than enough value for our users to warrant the subscription model.

  • http://zeroturnaround.com Jevgeni Kabanov

    Not any time soon. Sorry.

  • Mike

    I have no problem with the subscription model. I have a problem that the software disables itself after the year is up. If my Jira license expires it doesn’t disable itself, I simply stop getting support and upgrades. If my DbVisualizer license expires it doesn’t disable itself, I simply stop getting support and upgrades. If my IntelliJ license expires it doesn’t disable itself, I simply stop getting support and upgrades. See my point?

    Actually calling your disabling of software after license expiration “unfair” isn’t strong enough. The more appropriate word is Evil.

    I was actually going to renew my JRebel license, but when I saw the software disable itself I decided your company was too evil to do business with.
