Install it Maybe (Parody)
No redeploys. Tons of frameworks. Just code.
JRebel is a JVM plug-in that maps your project workspace directly to your running application. It allows developers to make changes to any class or resource in their IDE and the change is immediately reflected in the application, skipping the build and redeploy phases. On average, JRebel helps teams finish projects 17% faster and recovers 5+ weeks per year in lost time due to redeployment. Unlike standard JVM HotSwap, that only allows changes to method bodies, JRebel allows you to make add/remove methods, constructors, fields, classes, annotations, enum values as well as change interfaces on the fly. Technologically agnostic, JRebel integrates with all the major operating systems, application servers, IDEs and over 80 frameworks, making redeploys a thing a of the past. Join the rebellion!
