README

Development debugbar and request profiler for the Marko Framework.

Installation

composer require marko/debugbar --dev

Quick Example

With APP_DEBUG=true (or DEBUGBAR_ENABLED=true), the debugbar auto-injects into HTML responses and stores a snapshot for every request. Add custom messages and timings from anywhere in your app:

debugbar('Rendering dashboard', 'info', ['user_id' => $user->id]);

$report = debugbar()?->measure('build report', fn () => $this->reports->build());

Open /_debugbar to browse stored requests, or follow the X-Marko-Debugbar-Url header on JSON responses for the per-request profiler page.
