## What it is
Tracy is a PHP debugging library that provides error visualization, variable dumping, logging, and a floating debug bar (Tracy Bar) showing execution time, memory usage, and database queries. It supports AJAX call debugging, CLI usage, and profiling, and integrates with the Nette framework ecosystem.

## Use cases
- debug php code with visual error screens
- dump variables in php
- profile php script execution time and memory
- log php errors in production
- debug ajax requests in php
- add a debug bar to a php application
- see stack traces for php exceptions

## When to choose
- you develop PHP 8.2+ web apps or CLI scripts and want rich, visual debugging
- you use Nette Framework or want a framework-agnostic PHP debugger
- you need error logging plus a dev toolbar with request metrics

## When to avoid
- your project is not PHP
- you need a full IDE-integrated debugger like Xdebug step debugging
- you want a language-agnostic APM solution

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