## What it is
libbpf is the official stand-alone C library for loading and managing BPF programs and maps on Linux, developed upstream in the bpf-next kernel tree and mirrored to GitHub. The ecosystem includes libbpf-bootstrap for example BPF applications and libbpf-rs, a safe idiomatic Rust wrapper around libbpf.

## Use cases
- write eBPF programs that trace kernel and user-space events
- load and manage BPF objects from a C application
- build CO-RE (compile once, run everywhere) BPF applications
- develop custom Linux observability and tracing tools
- write eBPF tooling in Rust with a safe API
- instrument networking, security, or performance monitoring via BPF

## When to choose
- you need low-level, kernel-synced BPF loading APIs on Linux
- you want CO-RE portability for BPF programs across kernel versions
- you are building tracing or observability tools like bpftrace-style utilities
- you want a safe Rust interface to eBPF via libbpf-rs

## When to avoid
- you need BPF on non-Linux platforms
- you want a high-level scripting tool rather than a library (consider bpftrace or BCC)
- you need Windows eBPF support

## Facets
- artifact type: library
- maturity: stable
- function: tracing, developer-tools, sdk
- domain: developer-tools, operating-systems, performance, monitoring
- platform: c, rust, cli
- tags: bpf, ebpf, libbpf, kernel, observability, co-re, bpf-rs, linux
