Looking for a package to limit user based on plan

Check out Laravel Permissions from Spatie. That package lets you define permissions and then group permissions into roles and give permissions and roles to any model in your system. So you can have a permission that says $user->can('create models')

Alternatively, instead of creating a bunch of different permissions and roles, you can simply create a table that stores the limits by plan in rows like this:

id		plan	post_limit	contact_limit
1		basic	5			5
2		premium	10			10
...

and then link that to a user on the users table:

id		name		plan_id
1		John Doe	1

so that in your User model you can check to see what plan they have, and you can write custom methods like postLimitReached

public function postLimitReached(): bool
{
    return $this->posts()->count() < $this->plan->post_limit;
}

so that in your PostController you can check if a user is allowed to create a new post:

public function create()
{
	$user = Auth::user();
	if($user->postLimitReached()) {
		//forbidden
		//but you can handle this however
		abort(403);
	} else {
		//show the form to create a new post
	}
}
