## What it is
Silex is a PHP micro-framework for building websites and simple web applications, built on top of Symfony components with a lightweight, Pimple-based service container. It is deprecated and reached end of life in June 2018, with Symfony 4 recommended as its replacement.

## Use cases
- build a small PHP web application with minimal boilerplate
- define simple REST endpoints with routing
- create a lightweight API on Symfony components
- prototype a PHP website quickly
- wire small services with a Pimple dependency injection container

## When to choose
- maintaining an existing legacy Silex codebase
- learning how micro-frameworks are built on Symfony components

## When to avoid
- starting any new PHP project — use Symfony instead
- projects needing long-term security support
- applications requiring modern PHP 8 features or Symfony 4+ ecosystem

## Facets
- artifact type: framework
- maturity: abandoned
- function: web-framework, routing, http-server, middleware
- domain: web-development, backend, apis
- platform: php, cross-platform
- tags: micro-framework, deprecated, symfony-components, pimple, end-of-life, web-server
