sharppcap
A fully managed, cross-platform .NET library for capturing network packets from live devices and files.
What is sharppcap?
SharpPcap is a fully managed .NET library for capturing and analyzing network packets from live interfaces and capture files. It solves the problem of cross-platform packet capture by providing a unified API that works on Windows, Linux, and macOS, abstracting away platform-specific details like libpcap and Npcap.
.NET developers building network monitoring tools, security applications, protocol analyzers, or any software requiring low-level network packet inspection.
Developers choose SharpPcap for its clean, modern API, cross-platform compatibility, and performance optimizations like ReadOnlySpan<> support, which avoids unnecessary memory allocations during packet capture.
