JBehave is an embeddable library that builds on the foundation of JUnit 4. JBehave scenarios are annotated with the JUnit @Test annotation.
Therefore any IDE that supports JUnit integration will automatically support JBehave.
Note for Eclipse users:
Some versions of Eclipse need to be aware of the JBehave source to enable the JUnit plugin for scenarios, as they can’t spot the @Test annotation in a class jar. The solution is to ensure that the source is available to the IDE, either using an a plugin such as M2Eclipse or by explicitly adding the source jar, available from the download page, to the library.

Note for JBehave 3.x:
JBehave 3.x allows a much easier integration into any IDE or running environment via the Embedder framework
