FRIDA is a free dynamic instrumentation toolkit which lets you inject your own scripts into black box processes. Works on Windows, macOS, GNU/Linux, iOS, Android, and QNX.

It’s Greasemonkey for native apps, or, put in more technical terms, it’s a dynamic code instrumentation toolkit. It lets you inject snippets of JavaScript or your own library into native apps on Windows, macOS, GNU/Linux, iOS, Android, and QNX. Frida also provides you with some simple tools built on top of the Frida API. These can be used as-is, tweaked to your needs, or serve as examples of how to use the API.
