## What it is
Whoops is a PHP error handling library that provides a stack-based system for dealing with errors and exceptions. It renders a detailed, pretty error page with stack traces, code highlights, and JSON/XML response handlers for web projects.

## Use cases
- display pretty error pages in PHP web apps
- debug PHP exceptions with stack traces and code highlights
- handle AJAX errors with JSON responses
- integrate error handling into Laravel, Silex, or Zend projects
- open referenced files in an editor from an error page

## When to choose
- you're developing a PHP web application and want readable, informative error output
- you need a flexible, extensible error handler with JSON/XML support
- you want stack traces with code context and editor integration during development

## When to avoid
- you need error handling in production with minimal overhead and no debug output
- your project is not written in PHP
- you need full APM-style monitoring and alerting rather than error display

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, logging, ui-components
- domain: developer-tools, web-development
- platform: php, cross-platform
- tags: error-pages, stack-traces, debugging, pretty-errors, php-library, web-server
