## What it is
Symfony WebProfilerBundle is a development tool that collects and displays detailed information about the execution of any HTTP request in Symfony applications. It injects a web debug toolbar into HTML responses and provides a web interface at /_profiler for inspecting profiles, and must never be enabled in production.

## Use cases
- inspect request execution details while developing a Symfony app
- debug slow requests with timing and performance data
- view profiler data for JSON API responses via the X-Debug-Token-Link header
- browse and analyze past request profiles at /_profiler
- build custom data collectors for application-specific profiling
- programmatically load profiling data from a response

## When to choose
- you develop Symfony applications and need request-level insight into performance, logs, and internals
- you want a debug toolbar and browsable profile history in your dev environment
- you need to create custom data collectors for your own bundles

## When to avoid
- you are running a production server - enabling it there creates major security vulnerabilities
- your project is not built on Symfony/HttpKernel
- you need APM-style continuous production monitoring rather than a dev-time tool

## Facets
- artifact type: plugin
- maturity: active
- function: monitoring, developer-tools, middleware
- domain: web-development, backend, developer-tools, performance
- platform: php, self-hosted
