An eBPF-based packet filtering framework.

bpfilter transforms how you control network traffic by leveraging the power of eBPF technology. This framework elegantly translates filtering rules into optimized BPF programs, bringing unparalleled performance and flexibility to your packet filtering needs.

Key features

• High performance: utilizes eBPF’s near-native performance capabilities

• Low overhead: minimal resource consumption with maximized efficiency

• Developer-friendly: clean architecture with clear separation of components

bpfilter combines two components: bfcli, a CLI that allows users to define filtering rules in human-readable text, and libbpfilter, a library that converts these rules into efficient BPF programs and manages their lifecycle.
