Application Development Panel

The Universal PHP Debug Panel

One panel for Symfony, Laravel, Yii — and beyond.

28 data collectors · 20+ live inspector pages · 40+ API endpoints
4 framework adapters · Language-agnostic API · 100% free & open-source

What is ADP?

ADP is the only debug panel that works across the entire PHP ecosystem. Install one tool — debug Laravel, Symfony, Yii 3, Yii 2, or any PSR-compatible framework from a single, modern UI.

Unlike Telescope, Symfony Profiler, or Clockwork — ADP is not locked to one framework. Switch projects, not tools.

Why developers choose ADP

28 auto-collectors — logs, SQL, HTTP, events, cache, mail, queues, middleware, exceptions, and more. Zero configuration.
Live Inspector — 20+ pages to X-ray your running app: routes, DB schema, Git, Composer, DI container, OPcache, translations, file explorer. No competitor has this.
Developer Toolkit — code generation, cURL builder, request replay, command palette (Ctrl+K), dark mode, PWA.
Multi-app & polyglot — debug microservices from one panel. Send data from PHP, Python, Node.js via OpenAPI 3.1.
Real-time — UDP + SSE streaming. No polling.
