Every SaaS starts the same way: you have an idea, and before you can build it, you spend weeks writing authentication, setting up admin panels, configuring billing, wiring up the frontend, and doing everything except the thing that actually matters — your product.
Saucebase exists to solve that problem.
Saucebase is a modular Laravel SaaS starter kit built on Laravel 13, Inertia.js, and Tailwind CSS 4 — with your choice of Vue 3 or React. It ships with the infrastructure every SaaS needs and gets it out of your way so you can focus on building what makes your product unique.
The core of Saucebase is its module system, powered by internachi/modular. Features are packaged as self-contained modules — Auth, Billing, Settings, Blog — each with their own routes, controllers, models, migrations, and frontend pages. Modules are active when installed via Composer and live directly in your repository.
But here's what sets Saucebase apart: modules are copy-and-own. When you install a module, you own it. It lives in your repository. You can edit it, extend it, break it, and fix it. There are no locked vendor packages to work around, no version conflicts to manage. Just clean, readable Laravel code that does exactly what you'd write yourself — except already written.
Here's what comes out of the box:
Saucebase isn't a framework on top of Laravel — it's Laravel, done right from the start. Whether you're building your first SaaS or your tenth, it gives you the foundation without the friction.
Your next product starts here.
Choosing a frontend framework used to mean committing to a stack for the life of your project. Saucebase 2.0 changes that — ship with Vue 3 or React 19, and every module works either way.
Most starter kits give you a locked box. Saucebase takes the opposite approach: when you install a module, the source code lands in your repo and it's yours to read, edit, and own.
Modern web dev has a tension between server productivity and rich interactivity. Laravel, Inertia.js, and Tailwind resolve it — and Saucebase wires all the pieces together so you don't have to.
