You just save, refresh, and see the changes right away. To achieve this, JRebel does not wrap classloaders around classes, but patches existing classloaders to make classes loaded through them reloadable using instrumentation. JRebel tracks changes that you make in your workspace, and updates them as you go, so you can keep focused on the code and stay in the zone without interruption. As a JVM plugin, JRebel supports a majority of real-world enterprise Java stacks and is easy to install into existing development environments. With support for over 100 frameworks, and many popular application servers, IDEs, and JVM languages, JRebel works out of the box for almost every stack. ## JRebel Reviews ### 1. JRebel - Splendid Java-based project development tool for our customer application build & delivery **Rating:** 3.5/5.0 stars **Reviewed by:** Neeraja V. | Senior Developer, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** December 09, 2021 **What do you like best about JRebel?** We employ JRebel in our organization thanks to its brilliant platform for our java application development. Code changes made within JRebel are fast and efficient, and we don't have to worry about redeployments in case of application failovers. It saves us plenty of time as it ensures us visibility of these modifications in real-time and clarity on the impact of these code changes on our application environments. **What do you dislike about JRebel?** It preserves the state of our java application in such a way that we don't have to worry about the underlying dependencies and configurational changes to the code. We simply focus on our customer standards for building our java applications, and it ensures their satisfaction to a great extent. So nothing to dislike about JRebel. **What problems is JRebel solving and how is that benefiting you?** We incorporate the features that JRebel provides for java application builds with the help of Eclipse IDE. We have licensed JRebel from Eclipse Marketplace and leverage its data connectors, application integrators, and other plugins, which are very convenient to develop our java application. JRebel enables secure credentials authentication in which we just keep our secrets in our local repository and import the file into our java project. This feature ensures to maintain the password integrity, and since the function call happens from Import, the end-user won't know the credentials as they are referenced from our local repository file. Dependency management is fantastic in JRebel as we clearly define all our dependencies in a declarative code structure, and JReact takes care of its mapping and utilization aspects thanks to its application integration and custom module framework. ### 2. Works as expected **Rating:** 4.0/5.0 stars **Reviewed by:** Mustufa K. | Senior Software Consultant, Enterprise (> 1000 emp.) **Reviewed Date:** November 03, 2021 **What do you like best about JRebel?** I have used JRebel for a Java project using Oracle ADF. It worked great and saved a lot of time during development. It helped loading Java changes in weblogic without having to restart the server. **What do you dislike about JRebel?** Could be a bit costly if it's usage is not justified based on the time saved. A lot of development environments might be able to support other open source tools. **What problems is JRebel solving and how is that benefiting you?** We were unable to hot load Java changes in weblogic, so there were a lot of local server restarts when developing features or fixing bugs, JRebel helped avoid these restarts and saved a lot of time in development. ### 3.

Bless for java developer with huge applications **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** April 12, 2019 **What do you like best about JRebel?** I worked a company who have a big monolithic application starting the server itself takes 15 minutes, every time we have a do changes and test it use to take forever and it was quite challenging for the developer to do code changes while testing. They one of the team members suggested using jrebel plugin for eclipse ide and it was a game changer as we made our development faster without restarting the application for every small change. **What do you dislike about JRebel?** Working with multi projects it was reflecting the changes on the depended project automatically we have to compile part for that i don't think of anything. Pricing might be not sure as we have few license for team. **What problems is JRebel solving and how is that benefiting you?** Make development faster. ### 6. Coding **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Mid-Market (51-1000 emp.) **Reviewed Date:** April 16, 2019 **What do you like best about JRebel?** The JRebel is a great coding language to fix bugs or add something new to the program. **What do you dislike about JRebel?** It can be harder, and once you mess up one symbol in the code, it will look nothing alike Java. Thus, ruining the development of the bug. **Recommendations to others considering JRebel:** Know what you are doing, and use the program's saftey to check over the code. One little error will increase the bug and add to the problem. **What problems is JRebel solving and how is that benefiting you?** I am coding to fix bugs and to patch cracked features to a program. A benefit, Java develops along JRebel. ### 7.
