## What it is
Jet is a fast, secure template engine for Go with a simple C-like syntax. It supports template inheritance, composition, auto-escaping, and produces descriptive error messages with low memory overhead.

## Use cases
- render html templates in a go web server
- template engine with inheritance and blocks for go
- fast templating for go applications
- auto-escaped templates to prevent xss
- include and import shared templates in go

## When to choose
- you need a fast, secure Go template engine with inheritance
- you want better error messages than html/template
- you need template composition like extends, blocks, includes

## When to avoid
- you only need the standard library html/template
- you need logic-less templates like Mustache or Handlebars
- your stack is not Go

## Facets
- artifact type: library
- maturity: stable
- function: templating, web-framework
- domain: web-development, backend
- platform: go, cross-platform
- tags: template-engine, html-templates, auto-escaping, template-inheritance, fast-templating
