## What it is
Pyrasite is a Python library and CLI tool for injecting arbitrary code into running Python processes using gdb. It supports cross-version injection (Python 2 and 3) and includes an optional GUI.

## Use cases
- inject code into a running Python process
- debug a live Python process without restarting it
- inspect runtime state of a hung Python application
- run code in a Python 2 process from a Python 3 host
- attach to a production Python process for diagnostics

## When to choose
- you need to introspect or modify a running Python process at runtime
- you want cross-version Python injection via gdb
- you're debugging a process you cannot restart

## When to avoid
- you need a general-purpose debugger with breakpoints and stepping
- gdb is unavailable or cannot be codesigned on your system
- you only need logging or metrics rather than code injection

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools
- domain: developer-tools
- platform: python, cli
- tags: code-injection, gdb, runtime-debugging, python-processes, debugging, linux, macos
