## **What is Scapy?**

### Manipulate packets

Scapy is a powerful interactive packet manipulation library written in Python. Scapy is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more.

### A REPL and a Library

Scapy can be used as a REPL or as a library. It provides all the tools and documentation to quickly add custom network layers.

### Cross-platform

Scapy runs natively on Linux, macOS, most Unixes, and on Windows with Npcap. It is published under [GPLv2](https://www.gnu.org/licenses/gpl-2.0).\
Starting from version 2.5.0+, it supports Python 3.7+ (and PyPy).
