SaaS4Builders Documentation

Complete documentation for the SaaS4Builders boilerplate — a production-ready Laravel 13 + Nuxt 4 multi-tenant SaaS starter with Stripe billing, team management, and AI-first developer experience.

Welcome to the SaaS4Builders documentation. This guide covers every aspect of the boilerplate — from initial setup to extending the platform with your own features.

SaaS4Builders is a commercial boilerplate for building multi-tenant SaaS applications. It combines a Laravel 13 API backend with a Nuxt 4 frontend, Stripe billing, team management, and a structured AI-first developer experience. Everything is Docker-ready and designed for production from day one.
