## What it is
A Symfony bundle that generates OpenAPI/Swagger documentation for REST APIs from PHP 8 attributes and code analysis. It exposes interactive docs (Swagger UI, Redoc) and machine-readable OpenAPI specs for Symfony applications.

## Use cases
- generate openapi spec from symfony controllers
- document rest api endpoints with php attributes
- serve swagger ui for my symfony api
- auto-generate api docs from dto classes
- produce openapi 3.0 yaml/json for a php backend
- integrate redoc documentation into symfony app

## When to choose
- you have a Symfony (6.4+) or PHP 8.1+ REST API and want docs generated from attributes
- you need OpenAPI 3.0 specs with Swagger UI or Redoc rendering
- you want docs kept in sync with your code automatically

## When to avoid
- you use a non-Symfony PHP framework or PHP below 8.1
- you rely on legacy annotations (removed in 5.x)
- you need Swagger 2.0 output (use bundle version 3)

## Facets
- artifact type: library
- maturity: active
- function: api-documentation, documentation, api-framework, middleware
- domain: web-development, apis, documentation, backend
- platform: php, self-hosted
- tags: symfony-bundle, openapi, swagger, redoc, rest-api, php-attributes, web-server
