If you build with React, you have probably felt this. The React part of a SaaS is the fun part. Components, hooks, a clean UI, fast interactions. Then you need the rest of the product.

You need a backend. You need login that is actually secure. You need to keep every customer's data apart. You need users, invitations, roles and permissions. You need settings, translations and a way to update the app without breaking it for everyone. Suddenly the fun React project is a long list of backend work.

The SaaS Laravel React Starter Kit gives you that whole backend, already built and connected to a React 19 frontend. You pay once, clone it, and you start with a working multi-tenant SaaS. You keep writing React. Laravel quietly does the heavy lifting.

Below, I will go through the problems React developers usually hit when building a SaaS, and show exactly how the kit solves each one.

The short version

• What it is: a complete SaaS foundation with a Laravel 13 backend and a React 19 + TypeScript frontend.
• What is ready: secure login with two-factor and passkeys, a private database for every customer, users, invitations, roles, permissions, custom domains, 17 languages, maintenance mode, menus and layouts.
• Price: $30, paid once. No subscription.
• What you keep: lifetime access to the private GitHub repository and weekly updates.
• License: unlimited projects, for yourself or for clients.

Problem 1: Two apps means twice the work

A common way to build a React SaaS is to create two separate apps: a React frontend and a backend API. It works, but it doubles your work. Two deployments. Two sets of routes. An API to design and document. Tokens and sessions to keep in sync. CORS errors at midnight.

The kit uses Inertia v3 to avoid all of that. In plain words, Inertia lets a Laravel controller send data straight to a React component as props. There is no separate API. You write a Laravel route and controller, and Inertia renders your React page with the data already there.

Laravel route → Controller → Inertia::render('tenants/index') → pages/tenants/index.tsx

You get the smooth, single-page feel of a React app, with one codebase, one deployment and Laravel's normal session-based security.

Problem 2: Login is never "just login"

The first login form takes an hour. A secure login system takes weeks. Password resets, email verification, two-factor codes, recovery codes, "confirm your password before changing this", account deletion. And now customers ask for passkeys.

The kit includes all of it:

• Login, registration and password reset
• Email verification and password confirmation
• Two-factor authentication with a QR code, setup key and recovery codes, plus a proper one-time code input
• Passkeys, so people can sign in with a fingerprint, face or device
• Profile, password, appearance and account deletion settings

It is built on Laravel Fortify, the same package behind Laravel's official starter kits. You are not betting your customers' accounts on a homemade auth system.

Two details make it ready for a real SaaS. Your internal team signs in to a central admin app, and your customers sign in to their own workspaces, with completely separate user tables. And you can switch registration, password reset, two-factor authentication and passkeys on or off per domain, without writing code.

Problem 3: Keeping customer data apart

Every SaaS must answer one serious question: how do you make sure customer A never sees customer B's data?

The common shortcut is one shared database where every table has a tenant_id column. It is easy to start with and easy to get wrong. One missing filter in one query, and private data leaks.

The kit takes the safer path. Every customer, or "tenant", gets their own database. The app looks at the address in the browser, such as acme.your-app.com, and connects to Acme's database. Globex, on globex.your-app.com, uses a different database entirely.

The kit also keeps these separate per tenant, automatically:

• Cache, so cached data never mixes between customers
• File uploads, which go to the tenant's own storage folder
• Background jobs, which remember their tenant and run against the right database

This is powered by stancl/tenancy, a trusted Laravel package, fully set up and connected to the rest of the kit. In your own code, you do not need to add where tenant_id = ... to every query.

Problem 4: Onboarding every new customer by hand

Without tooling, every new customer means creating a database, running migrations, creating an admin account and emailing a password. The kit turns that into one form.

When you create a tenant, the kit:

1. Creates the tenant's database
2. Runs the migrations and seeders
3. Creates the tenant's admin user
4. Sends the admin a signed invitation link to set their password

You can resend the invitation, send a password reset link or set a password yourself. Your tenant list includes search, a status filter and stats, and every workspace has a status: Active, Trial, Pending Invitation or Suspended.

Problem 5: Permission checks scattered everywhere

In many React apps, permission logic ends up copied into dozens of components, and it drifts out of sync with the backend. A button shows up for someone who cannot use it, or worse, the backend forgets to block the request.

The kit puts the rules in one place. Roles and permissions use spatie/laravel-permission. Permissions are defined in config files, with separate files for your central app and for tenants. System roles are protected, new custom roles start empty and you can give a single user extra permissions without creating a new role.

Then the same rules are respected everywhere: routes, menu items and buttons. In React, checking a permission is one hook call:

export default function Index({ tenants }: { tenants: Tenant[] }) {
    const { can } = usePermission();

    return (
        <>
            {can('Create Tenant') && <CommonButton>New tenant</CommonButton>}
            <TenantList tenants={tenants} />
        </>
    );
}

That is a simplified example, but the pattern is exactly what you get: typed page props, one hook, one check.

User management is ready too. A users page with search, stats and pagination. Invitations by email with a signed link that is valid for 7 days. An "Invitation pending" badge until the person accepts. An accept page where they choose their own password.

Problem 6: Customers who do not speak English

Selling worldwide means translating your product, and translations tend to be messy in React apps. You end up with one set of files for Laravel and another set of JSON files for the frontend, slowly drifting apart.

The kit ships with 17 languages, including English, Hindi, Spanish, French, German, Japanese and Korean. Each user chooses their language, each domain has a default and even validation errors are translated.

Translations live in normal Laravel language files. Your React components read them through Laravel Lang Sync Inertia, an open source package I maintain:

import { reactLang } from '@erag/lang-sync-inertia/react'

const { __ } = reactLang()

__('modules.tenant.index.title')

One source of truth for every string, in Laravel and React.

Problem 7: Updates that take everyone offline

When you run a big migration or fix data across customers, you need maintenance mode that is smarter than "the whole site is down".

The kit lets you put every tenant workspace into maintenance with your own message on a friendly 503 page. A secret bypass link unlocks a workspace for 12 hours, so you can check your work while customers wait. You can let specific IP addresses through. Tenant login stays open, so admins can still get in, and your central admin app never goes down.

If a customer stops paying, you can suspend a single workspace with a message, and nobody else is affected.

Problem 8: "Can it have our name on it?"

Business customers often want the product to feel like theirs. The kit handles that at the domain level. Each tenant has a primary domain and any number of extra domains, and each domain has its own:

• App name, shown in the sidebar, sign-in pages and emails
• Default language
• Sign-in options, such as registration, two-factor and passkeys

On top of that, the look of the app is configurable without code. Menus live in the database and you reorder them with drag and drop. Choose a sidebar or header layout, an inset, regular or floating sidebar, an icon rail, slide-out or always-open sidebar, card, simple or split sign-in pages and light, dark or system mode.

What makes this a real React kit

All three SaaS Laravel kits share the same backend. The React kit is written the way modern React is meant to be written, not translated from another framework.

React 19 with the React Compiler

The kit runs React 19.2 in strict mode, with the React Compiler turned on in Vite. In simple terms, the compiler handles much of the memoization you would otherwise do by hand with useMemo and useCallback. You write plain function components, and the compiler helps keep re-renders in check.

Typed pages, from Laravel to TypeScript

Every page is a function component that receives its data as typed props. Those types are generated from Laravel Data classes, and every route is available as a typed function through Laravel Wayfinder. When a route or a data shape changes in Laravel, TypeScript shows you every React file that needs updating, before your customers find the bug.

Hooks for the everyday jobs

Shared logic lives in hooks under resources/js/hooks:

• usePermission() for permission checks
• useConfirmDialog() for one shared confirm dialog before deletes and risky actions
• useLanguage() for language switching
• useClipboard(), useDebounce(), useIsMobile() and useInitials() for small things every app needs
• useFlashToast() to turn Laravel flash messages into toasts automatically

A form kit built on shadcn/ui

The kit includes its own Common* components on top of shadcn/ui and Radix UI: inputs, password fields with show and hide, textareas, selects, radios, checkboxes, labels, errors, buttons with loading states, tooltips and a confirm dialog. They accept normal HTML props, plus a label and an error.

CommonButtonRow adds a Save / Discard bar that only appears when a form has unsaved changes. Forms use Inertia's Form component with render props, so errors and processing are right there in your JSX, and validation messages arrive from Laravel already translated.

Tools React developers already like

• shadcn/ui components, with every file in your project to edit
• Tailwind CSS v4 for styling
• sonner for toasts
• lucide-react icons
• sortablejs for the drag-and-drop menu builder
• input-otp for two-factor codes
• tsc type checking, ESLint and Prettier, plus an SSR build if you need one

Files follow familiar React naming: kebab-case component files like common-input.tsx, pages under resources/js/pages and hooks named use-x.ts.

Clean on the inside, too

The Laravel side is organised into modules: Auth, Dashboard, Menu, RolePermission, Settings, Tenant and User. Each module keeps its routes, controllers, validation, services and logic in one folder, so features do not bleed into each other. When you add billing or your own feature, it becomes a new module.

Tests and tooling are ready from the start: Pest tests, Larastan, Pint, ESLint, Prettier and a GitHub Actions workflow. Day to day you only need three commands:

composer setup   # install, configure, migrate and build
composer dev     # server, queue, logs and Vite in one terminal
composer test    # lint, type check and run the test suite

If you work with an AI coding agent, Laravel Boost guidelines and skills are included, so the agent learns the kit's patterns instead of guessing.

What is not included

So there are no surprises:

• No billing module. It is left out on purpose, because every SaaS needs a different payment provider, currency setup and pricing model. You add Stripe, Paddle, Lemon Squeezy, Razorpay or any provider you like as a separate module.
• MySQL is required for the database-per-tenant setup. Laravel Herd is recommended locally because it handles subdomains for you.
• You need some Laravel knowledge. You will write your features in Laravel and React. The kit gives you the foundation, not a drag-and-drop builder.
• No refunds. The full source code is yours as soon as you pay, and GitHub Sponsors does not refund sponsorships. The documentation is public, so you can read it all before deciding.

Is $30 worth it?

Think about what the alternative costs. Building secure auth with two-factor and passkeys, database-per-tenant multi-tenancy, tenant provisioning, invitations, roles, permissions, custom domains, translations and maintenance mode, with tests, is several weeks of work for an experienced developer.

The React kit is $30, once. That is less than an hour of freelance time in most places, and you can use it on every project you build.

Your $30 includes:

• The full Laravel backend and React frontend source code
• Lifetime access to the private repository
• Weekly updates that you merge whenever you are ready
• A commercial license for unlimited projects, including client work
• Support through GitHub issues

The kits launched on 28 September 2026 and shipped four releases in their first two weeks, including upgrades to Laravel 13.35, Inertia Laravel 3.5, Fortify 1.41 and Pest 5.3. You can follow every change in the public release notes.

There is also a practical business reason to pick React: it has the largest pool of frontend developers. If you plan to hire, a React codebase is easy to staff.

The only restriction is that you cannot resell, share or publish the kit's source code itself.

Who should buy the React kit?

• React developers who want a real backend without building and maintaining an API
• Founders who want to launch a B2B SaaS quickly and plan to grow a team
• Agencies and freelancers who build client SaaS projects and want one solid base for all of them
• Teams moving from a separate SPA and API to a simpler single codebase

Prefer another frontend? The Laravel Vue SaaS starter kit and the Laravel Svelte SaaS starter kit use the exact same backend. Agencies often pick the All Starter Kits bundle: Vue, React and Svelte for $79.

Getting started

1. Open the React kit pricing page and pay $30 through GitHub Sponsors.
2. Accept the GitHub invitation to the private repository. It arrives automatically.
3. Clone the kit and run composer setup.
4. Run composer dev, open the app and sign in as the super admin.
5. Create your first tenant and start building the feature that matters.

The React kit documentation covers everything in detail, and you can read it before you buy.

Frequently asked questions

Is it a subscription?

No. $30, paid once. Lifetime access and weekly updates are included.

Do I need to know Laravel?

You should be comfortable with the basics: routes, controllers and migrations. The kit follows standard Laravel patterns, so it is also a good way to learn how a well-structured Laravel app fits together.

Is this like Next.js?

It is a different approach. Instead of a JavaScript server, Laravel handles routing, data, auth and the database, and React handles the interface. Inertia connects them, so there is no API in between. Many React developers find it simpler to run.

Can I use it for clients?

Yes. Unlimited projects for yourself or for clients. You cannot resell or share the kit's code on its own.

Can I restyle everything?

Yes. Every component is a shadcn/ui file in your project, styled with Tailwind CSS v4.

What happens if I skip updates?

Nothing. Your code keeps working. Updates are optional, and you merge them on your schedule.

Write React, ship a SaaS

You should not have to become a full-time backend developer to launch a React SaaS. With this kit, the secure, multi-tenant backend is already done, and you spend your time where React shines: building an interface your customers love.
