Laravel

composer require shibbirweb/peep:@beta --dev

Laravel 5.5 to 13 discover the package by themselves. Peep is on in every environment except production (force it with PEEP_ENABLED). Publish the config to change what is captured:

php artisan vendor:publish --tag=peep-config

What shows up without any call

Setting (config/peep.php)	Default	Shows
send_logs	on	Log messages, with their context; logged exceptions as exception cards
send_exceptions	on	Reported exceptions
send_mail	on	A preview card of every mail sent, linked to the inbox
send_sms	on	SMS notifications in the SMS inbox
send_dumps	on	dump() and dd(), which still print as usual (dumps_passthrough)
send_queries	off	Every query (query_types picks which kinds)
send_slow_queries, slow_query_ms	off, 500	Queries slower than the threshold
send_duplicate_queries	off	Queries repeated within a request (N+1)
send_events, send_jobs, send_cache, send_http_client, send_views, send_requests	off	The other watchers
send_deprecations	off	PHP and framework deprecations

Every card carries the request, job or command it came from, and the viewer groups them.

Query debugging from the viewer

The toolbar of the viewer has Queries switches for each project: All, Slow (with a threshold) and Duplicates, each on, off, or "App default" (the config). A running app picks up a change within five seconds, with no restart.

In code

peep()->showQueries();                                  // from here on
$orders = peep()->showQueries(fn () => Order::with('items')->get());   // only inside
peep()->showSlowQueries(100);
peep()->showDuplicateQueries();
peep()->countQueries(fn () => $order->load('items'));   // how many queries, and their total time

peep()->showJobs()->showHttpClientRequests();
peep()->model($user);                                   // attributes, changes, relations
peep()->mailable(new InvoiceMail($order));              // rendered
collect($rows)->peep()->sum('total');                   // ->peep() passes the collection on
User::where('active', true)->peep()->get();             // the SQL with bindings
$this->get('/orders')->peep()->assertOk();              // a test response

The full list is in the API reference.

Blade

@peep($order)
@peepAll          {{-- every variable the view has --}}
@peepMeasure      {{-- time since the last @peepMeasure --}}

Mail and SMS

MAIL_MAILER=peep      # Laravel 7+ (MAIL_DRIVER=peep on 5.5 to 6): every mail goes to the viewer's inbox
PEEP_BLOCK_SMS=true   # SMS notifications go to the inbox only, never to a phone (never in production)

See Mail and SMS and, to simulate delivery webhooks back to your app, Webhooks.

Log files

The app reports storage/logs to the viewer, whose Logs tab then shows laravel.log and the daily files as colored entries, live. Set PEEP_LOG_PATH for another folder, or false for none. See Logs.

Docker (Sail)

PEEP_HOST=host.docker.internal
PEEP_REMOTE_PATH=/var/www/html
PEEP_LOCAL_PATH=/Users/you/code/shop

On Linux, also see Docker and other machines.

Before you ship

php artisan peep:clean          # lists leftover peep() calls; exit code 1 when there are any
php artisan peep:clean --fix
