Npcap

Npcap is a packet capture and network analysis library for Windows, designed as a modern replacement for WinPcap. It provides a high-performance, reliable API for capturing raw network packets, enabling applications like network monitoring, security analysis, and protocol debugging. Npcap is open-source and integrates with popular tools such as Wireshark and Nmap.

Also known as: Npcap Library, Npcap for Windows, Npcap Packet Capture, Npcap API, Npcap Driver

Why learn Npcap?

Developers should learn Npcap when building network-centric applications on Windows that require low-level packet inspection, such as intrusion detection systems, network scanners, or custom protocol analyzers. It's essential for tasks like capturing live traffic, analyzing network performance, or developing security tools that need to intercept and process packets in real-time.
