Larastrap has been inspired by many other works, and probably inspired some one else. Here a list of related projects, to be used both as alternatives or integrations.
A cool library to handle forms as code structures.
The laravel-form-bridge package provides more advanded integration with Laravel (even if using Twig instead of Blade...).

Somehow similar to Larastrap (and announced after Larastrap itself), but based on the Tailwind CSS framework.
Implements a code-oriented approach for personalization of reusable components.
Not an alternative, but probably the most easy way to install Bootstrap on your Laravel project.
Includes all utilities to provide, out of the box, login, registration, password reset and more, all implemented with simple Bootstrap templates.
Yet not an alternative, but a complementary project: it implements breadcrumbs and supports Bootstrap5 theming.
It does it so well, that it is the actual reason why Larastrap doesn't include a "Breadcrumb" component: just install it!
