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

Since migrating to IBM WAS 7.0, we've had trouble with replacing HotCode - we're now using JRebel for uninterrupted development and it's working fine :)

I heard about JRebel from my colleague who highly recommended using it. After trying it out a couple of times, it made perfect sense to me, and I haven't looked back since. Great product.

Over the last 265 days JRebel prevented at least 1,209 redeploys/restarts saving me about 49 hours.

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.

Senior System Analyst Programmer

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. The JSF memory footprint was a bad surprise - some beans are in the session, that shouldn’t have been there.

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

JRebel is really an amazing tool.

Jrebel is pretty much well known but I never really considered trying & buying it because most of my projects were not so complex. Now I have a much bigger project and applying code changes becomes more difficult so I decided to give JRebel a try. So far, trial version worked perfectly.

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

Why isn't JRebel part of the standard Java SDK?

Everyone who has tried it has fallen in love with it.
