JRebel is a JVM-plugin that makes it possible for Java developers to instantly see any code change made to an app without redeploying. JRebel lets you see code changes instantly, versioning classes and resources individually and updating one at a time instead of as a lump application redeploy. When developers make a change to any class or resource in their IDE, the change is immediately reflected in the deployed application, skipping the build and redeploy phases and preventing an average of 5.25 work weeks per year in redeploys!
What Does JRebel Do?
- Instant Reload
See all changes to Java code instantly in the browser. Save and refresh! The same is true for your other project files.
- Ecosystem Support
All major IDEs, application servers, servlet containers and frameworks are supported out of the box.
- Local or Remote
Run your server locally, remotely or in the cloud and see instant code changes.
- Instant Builds
All classes and resources are loaded from workspace. Even with Maven! No more time spent on building WAR archives.
