## What it is
Stencil is a template language and engine for Swift with a syntax similar to Django and Mustache. It lets Swift applications render text templates with variables, tags, and filters, and is used by tools like Sourcery and SwiftGen.

## Use cases
- render html templates in a swift server application
- generate swift code from templates
- use django-style templates in swift
- build a static site generator in swift
- separate presentation logic from swift code

## When to choose
- you are writing Swift and want Django/Mustache-style templating
- you need a mature template engine used by tools like Sourcery and SwiftGen
- you want extensible custom tags and filters in Swift

## When to avoid
- you need templating in a non-Swift language
- you want logic-heavy templates with embedded program code
- you need extremely high-performance streaming rendering

## Facets
- artifact type: library
- maturity: stable
- function: templating, parser
- domain: web-development, developer-tools, programming-languages
- platform: -
- tags: django-templates, mustache-like, swift-package, code-generation, swift, macos, linux, ios
