## What it is
A high-performance C++17 inter-process communication library using shared memory, supporting Linux, Windows, and FreeBSD. It provides lock-free channels and routes for broadcasting messages between processes with no external dependencies beyond the STL.

## Use cases
- send messages between processes using shared memory
- build a high-performance pub-sub channel in C++
- replace sockets with faster local IPC
- broadcast data from one process to many readers
- communicate between C++ processes on Linux and Windows

## When to choose
- you need low-latency, high-throughput local IPC in C++
- you want a dependency-free, header-light library installable via vcpkg
- you need cross-platform shared-memory messaging (Linux/Windows/FreeBSD)

## When to avoid
- you need network or cross-machine communication
- you need more than 32 receivers per channel
- your project targets C++ standards older than C++17

## Facets
- artifact type: library
- maturity: active
- function: concurrency, serialization
- domain: developer-tools, microservices, cross-platform
- platform: windows, cpp, cross-platform
- tags: ipc, shared-memory, lock-free, message-passing, cpp17, broadcast, high-performance, linux
