🔗 Laravel Doctor: Diagnose your app with one artisan command

Laravel Doctor was announced at Laracon US 2026 in Boston, introducing an artisan doctor command that performs health checks on Laravel applications. This command ensures essential configurations are correct, such as verifying the presence of the .env file, checking the APP_KEY, confirming PHP version compatibility, and making sure required extensions are installed. If issues are found, Doctor can automatically fix them where possible or clearly state what needs attention.

Each diagnostic is grouped into classes handling specific checks—covering environment, Composer dependencies, configuration, database connectivity, and more. The command can be extended by packages that want to add custom diagnostics, making it a versatile tool for maintaining application health. With the ability to provide machine-readable reports, Laravel Doctor is designed not only for developers but also for CI environments and AI coding agents, ensuring robust application maintenance across various setups.
