debugd for Laravel

Zero-instrumentation request tracing for Laravel — the passive collector for the debugd server.

It quietly ships each request's queries, logs, timings, exceptions, and your own dumps to a local debugd server, which serves a live UI. When DEBUGD_HOST is unset, the package does literally nothing — no listeners, zero overhead — so it's safe to leave installed.

your Laravel app  ──POST /ingest──▶  debugd (one Go binary)  ──live UI──▶  your browser

This is the read-only split of ShahramMebashar/debugd (the debugd-laravel/ directory). Open issues and PRs there.

Requirements

• PHP ^8.2
• Laravel 11, 12, or 13 (illuminate/support ^11 || ^12 || ^13)

Install

composer require --dev debugd/debugd-laravel
echo "DEBUGD_HOST=http://localhost:9100" >> .env

Start the debugd server (./bin/debugd --open), hit any page that does some work, and the trace shows up instantly. Remove DEBUGD_HOST and the package goes inert again.

The service provider is auto-discovered — no manual registration needed.

The debugd() helper

Leave these in your code. They're a no-op in production (when DEBUGD_HOST is unset), and bench() still returns its result either way.

debugd($user);                                  // dump anything into the trace
debugd()->dump($payload, 'stripe response');    // ...with a label
$rows = debugd()->bench('report', fn () => Report::heavy());  // time it, get the result
debugd()->info('reached checkout', ['step' => 3]);

// run things in parallel (real parallelism under Octane, sequential otherwise),
// each shown as its own span:
[$user, $orders] = array_values(debugd()->concurrently([
    'user'   => fn () => User::find($id),
    'orders' => fn () => Order::recent($id),
]));

Configuration

How it works

The package hangs off DB::listen, a Monolog handler, and the exception reporter, buffers everything per-request, and POSTs it from terminate() after the response is already sent — with tight timeouts and every failure swallowed, so tracing can't slow down or break a request. It's Octane- and FrankenPHP-safe (state is per-request, tested).

Not doing (on purpose)

No persistence, no production telemetry, no sampling, no auth. It's a local dev tool. The frozen wire format lives in PROTOCOL.md.
