## What it is
Collision is a PHP library that provides beautiful, readable error reporting for command-line applications. Built on top of Whoops, it is bundled with Laravel and supports Symfony, PHPUnit, Pest, and other frameworks.

## Use cases
- pretty-print php exceptions in the console
- improve error output for php cli scripts
- readable stack traces for phpunit test failures
- add better error reporting to a symfony console app
- debug laravel artisan command errors

## When to choose
- you write PHP command-line applications or console commands
- you want clearer exception output in PHPUnit/Pest test runs
- you maintain a Laravel or Symfony app and want better CLI error rendering

## When to avoid
- your project is not PHP
- you only need error reporting in web responses rather than the console
- you need a logging or monitoring solution rather than developer-facing error display

## Facets
- artifact type: library
- maturity: active
- function: error-handling, cli, developer-tools, testing
- domain: developer-tools, testing
- platform: cli, php, cross-platform
- tags: error-reporting, exceptions, laravel, symfony, phpunit, whoops, console-output, command-line, php
