Why DebugPHP

Debugging shouldn't
cost you money.

Existing tools are either paid, desktop-only, or require complex setups. DebugPHP is the free, open-source PHP debugging tool — a modern var_dump alternative that shows your output live in the browser.

Features

Everything you need.

Instant Real-Time Output

string(27) "User login successful"

object(User) (5) { ... }

db-query: 23.4ms

array(12) { [0] => ... }

Two Lines to Start

No config files. No IDE plugins. No browser extensions. Install, initialize, and send. That's it.

use DebugPHP\Debug;
Debug::init('token');
Debug::send($data);

Self-Hostable

Keep your debug data on your own server. Clone, composer install, run the setup wizard — done.

Framework Support

Designed to plug into modern PHP applications and frameworks with minimal effort. Use DebugPHP in the stack you already have, without framework-specific lock-in.

Labels & Colors

Tag entries with types, labels, and colors. Filter by SQL, Error, Timer, or any custom type.

Live Toolbar Metrics

Push key-value pairs to the dashboard toolbar. Auto-cleared when no longer sent in a new request.

PHP-Native Type Rendering

Objects, arrays, and exceptions rendered in a familiar var_dump-style tree — with class names, string lengths, and full stack traces for exceptions.

object(App\Models\User) (4) {
  ["id"] => int(42)
  ["name"] => string(4) "Leon"
}

Getting Started

Ready in 60 seconds.

Install via Composer

Add DebugPHP as a dev dependency. Works with Laravel, Symfony, WordPress, or plain PHP.

$ composer require callmeleon167/debugphp --dev

Create a Debug Session

Open the Dashboard, click + New Session, and copy your unique session token.

Session: a3f8c1d2e5b7... Copy token

Initialize & Send

Call Debug::init() once at your entry point. Then Debug::send() anything, anywhere.

Debug::init('a3f8c1d2e5b7');
Debug::send($user);
Debug::send($query, 'SQL')->color('blue');
Debug::metric('Memory', memory_get_usage(true));
