Frida is a dynamic instrumentation toolkit for developers, reverse-engineers, and security researchers. It lets users place scripts in running processes to hook functions, inspect APIs, and trace application code without source code. Documented uses include API tracing, diagnostics, encrypted-protocol analysis, and black-box testing.

Frida supports injected, embedded, and preloaded instrumentation. When injection is unavailable, Frida Gadget can be embedded in a program, including on jailed iOS and Android systems. Supported targets include Windows, macOS, GNU/Linux, iOS, watchOS, tvOS, Android, FreeBSD, and QNX. Language bindings include Node.js, Python, Swift, .NET, Qt/Qml, and Go, alongside a C API. The CLI tools require Python and run on Windows, macOS, or GNU/Linux; the documented installation command is `pip install frida-tools`.
