It supports a wide range of protocols and can be used interactively as a shell or imported as a library in Python scripts. The library handles classical network tasks like scanning, tracerouting, and probing, but also excels at specialized work such as crafting malformed frames, injecting 802.11 packets, and combining advanced techniques like VLAN hopping or ARP cache poisoning.\n\nThe package has no required runtime dependencies and works on Linux, BSD, macOS, and Windows (with platform-specific setup). It requires Python 3.7 or later and is actively maintained. Most operations require root or administrator privileges to access raw sockets. Optional features like plotting or cryptography support can be added by installing additional packages separately.","worth_installing":"Yes, if you need low-level packet manipulation and network analysis. Scapy is production-stable, actively maintained, has no required dependencies, and is widely used for security research and network engineering. However, the GPL-2.0 copyleft license is a hard blocker for proprietary software, and you must have root/administrator access to use packet capture and injection features. Evaluate the license constraint first."},"id":"scapy","links":{"html":"https://skillfed.io/packages/scapy","md":"https://skillfed.io/packages/scapy.md","pypi":"https://pypi.org/project/scapy/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-26","license_spdx":null,"license_treatment":"copyleft","name":"scapy","python_support":"supports_current","summary":"Scapy: interactive packet manipulation tool"},"popularity":{"monthly_downloads":5230356,"position":2134,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.7.0"}
