## What it is
A PHP library that renders an in-browser debug bar showing collected data from PHP applications, including messages, timing, memory, exceptions, database queries, and request data. It integrates with popular libraries like PDO, Monolog, and Symfony, and supports custom collectors, AJAX request tracking, and persistent storage of collected data.

## Use cases
- debug PHP applications without var_dump
- inspect database queries and timing in the browser
- profile memory usage and execution time of PHP requests
- debug AJAX requests in PHP apps
- view exceptions and PHP info during development
- collect and re-open debug data from previous requests
- add a debug bar to Laravel or Symfony projects

## When to choose
- you develop PHP applications and want rich in-browser debugging
- you need query, timing, and memory profiling during development
- you want a framework-agnostic debug bar with easy custom collectors
- you need AJAX request debugging with header-based data transfer

## When to avoid
- on production or publicly accessible websites (development use only)
- you need a full application performance monitoring (APM) solution
- your stack is not PHP

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, monitoring, logging, middleware
- domain: web-development, backend, developer-tools
