What do people build with it?

USE CASE 1

Reverse engineer a mobile app to understand its internal API calls and decrypt network traffic.

USE CASE 2

Hook functions inside a running process to trace inputs and outputs without attaching a traditional debugger.

USE CASE 3

Bypass certificate pinning in an Android or iOS app to inspect its HTTPS traffic during a security test.

USE CASE 4

Automate security testing by scripting Frida in Python to inject JavaScript into a target app and assert on its behavior.

What is it built with?

How do you get it running?

Difficulty · moderate Time to first run · 30min

Building from source on Apple platforms requires a valid code-signing certificate, most users should install via pip install frida or npm install frida instead.

In plain English

Frida is a dynamic instrumentation toolkit designed for developers, reverse-engineers, and security researchers. Dynamic instrumentation means it lets you inject code into running programs and inspect or modify their behavior in real time, without needing the program's source code. The repository itself exists primarily as the place to clone if you want to build Frida from source. The more common way to install it is through package managers: pip install frida for Python bindings, pip install frida-tools for command-line tools, or npm install frida for Node.js bindings. Pre-built binaries are also available on the GitHub releases page for various operating systems. The toolkit includes several CLI tools such as frida, frida-ps, frida-trace, frida-kill, frida-ls-devices, and frida-discover. Building from source on Apple platforms (macOS, iOS, watchOS, tvOS) requires a valid code-signing certificate. Full documentation is available at frida.re.

Copy-paste prompts

Prompt 1

I want to use Frida on Android to hook the SSL_write function and log plaintext HTTPS traffic from a specific app. Show me a Python script to do that.

Prompt 2

How do I use frida-trace to automatically trace all calls to functions matching a name pattern in a native binary on macOS?

Prompt 3

I want to bypass certificate pinning in an Android app using Frida. Walk me through the steps and show me a working Frida script.

Prompt 4

How do I use Frida's Python bindings to enumerate all loaded modules inside a running Windows process and dump the exports of one module?

Prompt 5

I want to build Frida from source on macOS. What do I need and how do I sign the output binaries so they run without errors?
