Laravel Schema Sentinel: Detect and Fix Database Schema Drift

Laravel Schema Sentinel by Ahtesham at Broadway Web Service detects schema drift— to help identify when your actual database no longer matches your migrations. It builds a shadow database from your migrations, diffs it against the live schema, and can generate a corrective migration when the two diverge.

Deep drift detection — audits tables, columns, data types, nullability, defaults, indexes, and foreign keys
Cross-environment comparison — verify local migrations match staging or production
Auto-generated migrations — create corrective migrations with interactive review
Visual dashboard — built-in Livewire component for database health monitoring
Pre-migration guard — automatically block php artisan migrate if drift is detected
And more...

Detecting Drift

The core command runs your migrations into a temporary shadow database, then compares that shadow against your live connection:

php artisan schema:drift

It checks tables, columns, data types, nullability, defaults, indexes, and foreign keys. Running with --strict also flags columns or tables present in the live database that have no corresponding migration.

Generating a Fix

When drift is found, you can have Sentinel generate a migration to close the gap:

php artisan schema:drift --fix --interactive

Interactive mode walks you through each detected difference before writing anything. A --sql flag skips file creation and prints the migration code to the terminal for review.

Cross-Environment Comparison

You can point the diff at a different environment's database connection instead of your local one:

php artisan schema:drift --compare-env=staging

This uses the named connection from your config/database.php, so you can verify your local migrations match what's deployed to staging or production before running them.

Programmatic API

A Sentinel facade exposes the same diff as a DTO, which you can use in controllers, Livewire components, or admin dashboards:

use Sentinel\SchemaSentinel\Facades\Sentinel;

$diff = Sentinel::check(strict: true);

return response()->json([
    'in_sync' => !$diff->hasDifferences(),
    'drift'   => $diff->toArray(),
]);
