OpenRemote software is Open Source. We manage our projects on Github.
We are currently maintaining OpenRemote v2 projects and work on a major v3 update. This new development is in One Big Repository, have a look at the current status and task list. Any task is up for grabs, please discuss on Github or here if there is something interesting in there for you. We use Java, Groovy, GWT, Gradle, Spock, Camel, RxJava, and some Java EE.
