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 90+. The company’s commercial 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.


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 and intrepid operations folks who keep existing Java apps humming (and up-to-date). You know, people like us. Here’s what some of them have said about life with tools we’ve made.

WHAT THEY SAY

JRebel seems to be the only cost effective way to accelerate the compilation and startup of our projects, consisting of several EAR artifacts deployed on a JBoss App Server. We have been using it for a year, and my development team is very pleased with it.

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.

Just started using JRebel; installation was done in 15 minutes and 1 hour later it saved me 20 minutes of restart time.

I like the way [JRebel monitors] the file system for changes and smartly reloads Java changes into Hot Swap/Hot code memory. It just eliminated by build time during development by 90%.

JRebel is like a drug for me, I am totally addicted to this tool because it saves a lot of nerves and energy and it is exactly what I need to speed up the software production process for my application.

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.

JRebel is a blast! After the 30-day evaluation version expired, I found it hard to code anymore :-) It was very frustrating developing the old way without JRebel. Thank you very much for this wonderful piece of software!

Alterar método, adicionar atributos, criar classes, restart servidor, isso era um ritual a cada hora do meu trabalho. Com JRebel posso alterar qualquer código java que já é refletido na aplicação em funcionamento. Muito bom.

I see JRebel as this "missing piece" in the whole picture where we could see Java-stack not only as a stable, well-tested environment to build applications on but also as a rapid development environment.

Jrebel is one those small non-intrusive pieces of software that you just can't live without!

So far, everybody I speak to about JRebel is satisfied with it - frankly, I cannot believe nobody thought of JRebel before.

It used to take 5 mins to rebuild and restart the server - now we see changes pretty much instantaneously. I saw the value right away.
