## What it is
Gproc is an extended process registry and dictionary for Erlang/OTP, supporting arbitrary-term aliases, multiple registrations, counters, and a global (multi-node) registry. It also enables pub/sub messaging and QLC/match-spec based queries over registered process metadata.

## Use cases
- register erlang processes under custom aliases
- build publish-subscribe messaging in erlang
- find processes by metadata in a running system
- wait for a process to register itself
- maintain aggregated counters across processes
- share a registry across a cluster of erlang nodes
- give away a registered name to another process atomically

## When to choose
- you need richer process naming than Erlang's built-in `whereis/1` allows
- you want pub/sub or process discovery patterns in an Erlang/Elixir app
- you need a global registry spanning multiple nodes

## When to avoid
- you only need simple single-name registration, which the built-in Erlang registry handles
- your system cannot tolerate the overhead of a central registry process

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, developer-tools
- domain: microservices, developer-tools, backend
- platform: elixir, windows
- tags: process-registry, pubsub, erlang, process-aliases, service-discovery, linux, macos
