## What it is
Fluid is an open-source .NET template engine implementing the Shopify Liquid template language. It offers a fast, secure parser with allow-listed member access, async filters, custom tags, and an AST for caching and analysis.

## Use cases
- render liquid templates in a .NET application
- let users safely write custom email or page templates
- build an ASP.NET MVC view engine using liquid
- parse and cache liquid templates as an AST
- expose user-editable templates without risking application security

## When to choose
- you need Shopify-compatible Liquid rendering on .NET
- security matters and templates must not access arbitrary members
- you need high-performance, low-allocation template rendering or async filters

## When to avoid
- you prefer Razor or another .NET-native templating syntax
- you need a template engine outside the .NET ecosystem

## Facets
- artifact type: library
- maturity: active
- function: templating, parser
- domain: web-development, developer-tools
- platform: dotnet, cross-platform
- tags: liquid, template-engine, shopify-liquid, view-engine, secure-templating
