Inject JavaScript to explore native apps on Windows, Mac, Linux and iOS.

Scriptable

Your own scripts get injected into black box processes to execute custom debugging logic. Hook any function, spy on crypto APIs or trace private application code, no source code needed!

Stalking

Stealthy code tracing without relying on software or hardware breakpoints. Think DTrace in user-space, based on dynamic recompilation, like DynamoRIO and PIN .
