A simple and fast packet networking toolkit for building high-performance network applications with Lua and kernel bypass.
Snabb is a packet networking toolkit for building simple and fast network applications. It solves performance bottlenecks in packet processing by using kernel bypass and LuaJIT, enabling high-speed networking without kernel overhead. It is used for applications like virtualized network functions, IPv6 transition, and load testing.
Network engineers, ISP operators, and developers building high-performance network elements or virtualized networking solutions. It is ideal for those needing to process up to 100 Gbps of traffic per server.
Developers choose Snabb for its combination of high-level Lua programming with near-C performance via LuaJIT, kernel bypass for maximum speed, and a stand-alone binary that simplifies deployment. Its community-driven approach and practical focus on real-world networking problems set it apart.

Uses direct Ethernet I/O without kernel overhead, enabling maximum packet processing speeds for applications like handling up to 100 Gbps traffic, as highlighted in the snabbnfv description.
Leverages LuaJIT for high-level programming with near-C performance, making development faster while maintaining speed, as stated in the 'How does it work?' section.
Compiles into a single executable that includes all applications, simplifying installation and portability across Linux systems, similar to busybox for networking.
Includes ready-to-use tools like snabbnfv for NFV, lwAFTR for IPv6 transition, and packetblaster for load testing, addressing practical networking challenges documented in the README.
Primarily optimized for specific hardware like Intel 82599 10-Gigabit interfaces, as seen in packetblaster, which may restrict use with other network cards without custom driver work.
Requires familiarity with Lua programming, which can be a hurdle for teams accustomed to more common networking languages like C or Python, increasing the onboarding effort.
The README points to an API reference and contributor hints, but lacks comprehensive tutorials or step-by-step guides for complex deployments, leaving gaps for newcomers.
