What is ADP?

ADP (Application Development Panel) is a framework-agnostic debugging and development panel for PHP applications. Think of it as a universal "developer toolbar" that works with any PHP framework.

The Problem

Every PHP framework has its own debugging tools:

• Symfony has the Web Profiler
• Laravel has Telescope
• Yii has the Debug Extension

But what if you work with multiple frameworks? Or want consistent tooling across projects? That's where ADP comes in.

The Solution

ADP provides a single, unified debugging experience that works across frameworks by leveraging PSR standards:

• PSR-3 (Logger) — Captures log messages
• PSR-7 (HTTP Messages) — Inspects requests and responses
• PSR-14 (Event Dispatcher) — Tracks events
• PSR-15 (HTTP Handlers) — Monitors middleware pipeline
• PSR-11 (Container) — Inspects dependency injection

Key Features

Collectors

ADP ships with collectors for common debugging scenarios:

Collector	What it captures
LogCollectorAppDevPanel\Kernel\Collector\LogCollectorCollects Log data during application lifecycle.Kernel · class · implements SummaryCollectorInterface	PSR-3 log messages
EventCollectorAppDevPanel\Kernel\Collector\EventCollectorCollects Event data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface	PSR-14 events
HttpClientCollectorAppDevPanel\Kernel\Collector\HttpClientCollectorCollects Http Client data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface	Outgoing HTTP requests
DatabaseCollectorAppDevPanel\Kernel\Collector\DatabaseCollectorCaptures SQL queries and transactions from the application.final Kernel · class · implements SummaryCollectorInterface	SQL queries and timings
ExceptionCollectorAppDevPanel\Kernel\Collector\ExceptionCollectorCollects Exception data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface	Caught and uncaught exceptions
MiddlewareCollectorAppDevPanel\Kernel\Collector\MiddlewareCollectorCaptures HTTP middleware stack execution data.final Kernel · class · implements SummaryCollectorInterface	PSR-15 middleware execution
ServiceCollectorAppDevPanel\Kernel\Collector\ServiceCollectorCollects Service data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface	DI container resolutions
AssetBundleCollectorAppDevPanel\Kernel\Collector\AssetBundleCollectorCaptures registered asset bundles from the application.final Kernel · class · implements SummaryCollectorInterface	Frontend assets
RouterCollectorAppDevPanel\Kernel\Collector\RouterCollectorCaptures HTTP routing data: matched route, match timing, route tree.final Kernel · class · implements SummaryCollectorInterface	Route matching and parameters

Real-time Updates

The panel uses Server-Sent Events (SSE) to push new debug entries to the browser in real-time. No need to refresh.

AI Integration

ADP includes an MCP (Model Context Protocol) server that exposes debug data to AI assistants like Claude. Ask your AI to analyze errors, suggest fixes, or explain complex request flows.

Philosophy

• Framework-agnostic — Works with any PSR-compliant framework
• Zero configuration — Install the adapter and it just works
• Non-intrusive — Uses proxies, not patches. Your code stays clean
• Extensible — Write custom collectors implementing CollectorInterfaceAppDevPanel\Kernel\Collector\CollectorInterfaceDebug data collector responsibility is to collect data during application lifecycle.Kernel · interface for your domain
• Modern stack — React 19, TypeScript, Material-UI on the frontend
