TallStack is a modern full-stack PHP approach combining Tailwind CSS (styling), Alpine.js (lightweight interactivity), Livewire (reactive components), and Laravel (backend). The philosophy is simple: write PHP, not JavaScript. Livewire lets you build reactive components (without page refreshes) while keeping logic on the server. Alpine.js adds client-side interactivity (dropdowns, modals, tooltips) without the overhead of React or Vue.
