THE STORY

“Software is eating the world,” said Netscape founder and tech investor Marc Andreessen. Line by line, hardware is being consumed by code, and Java is spoken by a massive army of hungry mouths.

However, since the programming language was introduced in 1996, developers have had to write Java code on their own machines and then upload their code to remote servers for testing.

The idea that would become a glass of ice water to coders in redeployment hell was born in Estonia in 2006. That’s when Jevgeni Kabanov found a way to address Java’s core problem – the redeployment bottleneck. His insight led to a start-up and two products that smart Java teams wouldn’t be caught without. In other words, magic happened.

Developers at thousands of companies around the world use JRebel to instantly view code changes without redeploying the application server.

The result? Happy coders writing and testing beautiful code. Happy customers enjoying time and money saved through all that beautiful, productivity-boosting code.

Today, ZeroTurnaround is the labor of love by a global team of 150+. The company’s go-to-market heart beats in Boston, Massachusetts, while our development feet are firmly planted (and rapidly growing) in Estonia, at two offices in Tallinn and Tartu. We also have a branch in Prague, Czech Republic.

We are dedicated to making developers lives better, and we now have over 65,000 active users at 5,200+ customers, including 36% of Fortune 100, in 80+ countries.


DEVELOPERS SAYING REALLY NICE THINGS

We’re developers who make stuff for people just like us. Yes, our software is used by companies, from startups to well-known multinationals. But at their core, our products are consumer products. It’s a stroke of good fortune that our “consumers” happen to be other Java developers. You know, people like us. Here’s what some of them have said about life with the tools we’ve made.

WHAT THEY SAY

We found it very useful to dig into the SQL queries. We quickly found some very lengthy and complicated queries. We also found that our session can get as large as 30 Mb - we had too many references to Spring beans in the session.

The time period between making a change, rebuilding, deploying and restarting the container has always been a sticking point with me, but JRebel allows me to develop constantly without bouncing back and forth. Personally, it's one of the more important pieces of software I've come across in quite some time.

JRebel is a real solution for build/deployment pain in Java EE. Good product. It just works and doesn't need a 3 hour configuration phase :)

I have been very impressed with JRebel, wish I had come across this product a lot sooner, would have saved me so much time/boredom waiting for so many container restarts.

Working with JBoss, Seam, JSF and the Eclipse JBoss Tools...It's very painful. I had read about JRebel a couple of times on theserverside.com and javalobby and decided to give it a try. It works great.

We’ve had some real OutOfMemory problems in our production environment for quite some time. Once I got XRebel up and running I noticed that our most used webapplication uses around 15MB/User session. By tuning a few JSF parameters I got the average user session from 15MB to 0,5MB.

We had a need for faster turnarounds since we have huge projects that take ages to build and deploy. Jrebel is an excellent tool to reduce that time:)

Over the last 78 days, JRebel prevented at least 1774 redeploys/restarts, saving about 71.9 hours!

JRebel is really great - it helped our team save a lot of hours!

I just hated the whole Eclipse IDE and one of my co-workers suggested I try Jrebel since 40% of my time was waiting on Eclipse to build and run. With Jrebel, things are going much smoothly now.

Arnold Serrano

Java Developer

Since evaluating JRebel, we have seen redeploy times significantly reduced and I am therefore hoping that we can be more productive and turn around our development projects in a quicker timeframe.

Start to really like JRebel. Make Java feel like a scripting language.
