Requirements

ArtisanPack UI Core is the foundation for every other ArtisanPack UI package, so its baseline requirements are the floor for the entire ecosystem.

PHP

• PHP 8.2 or newer is required. PHP 8.2 users continue to receive Laravel 12; PHP 8.3+ unlocks Laravel 13 (Laravel enforces its own PHP constraint).

Laravel

• Laravel 12 or 13 is supported. The composer constraint is ^12.0|^13.0.
• Laravel 11 is no longer supported as of Core 1.3. Every 11.x release carries unpatched security advisories and the branch is past its security-fix window, so Composer's advisory policy now refuses to install any of them — Core cannot install or test against a framework version that no longer resolves. Stay on Core 1.2.x if you must remain on Laravel 11, understanding that the framework itself is unpatched.
• Laravel 10 is no longer supported as of Core 1.1.
• Laravel 13 support was added in Core 1.2 — the package transparently degrades to Laravel 12 APIs on older framework versions and uses the artisanpack_supports_laravel_13() helper or method_exists() feature detection where Laravel 13-only APIs are involved.

PHP extensions

The same extensions Laravel core itself requires are enforced by the diagnostic runner's EnvironmentCheck:

• ctype
• json
• mbstring
• openssl
• pdo
• tokenizer

A missing extension is reported as an error by php artisan artisanpack:diagnose.

Other ArtisanPack UI packages

Every sibling ArtisanPack UI package declares artisanpack-ui/core: ^1.0 in its composer requirements. Adding any sibling package therefore pulls Core in automatically — you only install Core directly if you want the diagnostic / compatibility / update tooling on its own.

Use php artisan artisanpack:check-compatibility to confirm every installed sibling package satisfies its declared constraints against the running PHP / Laravel / extension stack.
