Standalone PHP

The profiler core does not need Laravel:

$stopwatch = \SanderMuller\Stopwatch\Stopwatch::new();
$stopwatch->start();
$stopwatch->checkpoint('Done');
echo $stopwatch->toString();

What is Laravel-only:

Feature	Needs
stopwatch() helper	the container
Query tracking	illuminate/database and an application
Config-based setup, channel resolution from class strings	the container
Toolbar, Server-Timing middleware, Debugbar tab, run log	an application
