## What it is
GRMustache is a flexible, production-ready Mustache template engine written in Objective-C for macOS Cocoa and iOS, depending only on Foundation. It extends the strict Mustache language with built-in goodies and extensibility hooks, and can also be used from Swift with Objective-C objects.

## Use cases
- render mustache templates in an iOS app
- generate HTML emails from templates on macOS
- render templates from strings or bundle resources in Objective-C
- reuse parsed templates to render multiple data objects
- extend mustache syntax with custom tags in Cocoa apps

## When to choose
- you need a battle-tested Mustache engine for Objective-C or mixed Objective-C/Swift iOS or macOS projects
- you want Mustache with extensibility hooks beyond the standard minimal language
- you target older iOS/macOS versions and want a Foundation-only dependency

## When to avoid
- you are writing a pure Swift project - prefer GRMustache.swift or Stencil instead
- you need server-side or non-Apple platform templating
- you need actively developed features - the library is in maintenance mode with infrequent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: templating, parser
- domain: web-development, developer-tools, mobile-development
- platform: cpp
- tags: mustache, objective-c, template-engine, cocoa, text-templating, macos, ios, swift
