Laravel Svelte SaaS Starter Kit

Our Laravel SaaS backend with a Svelte 5 frontend written with runes and TypeScript. The UI is built from shadcn-svelte components on Bits UI, and shared .svelte.ts modules handle permissions, layout and translations.

Features

What's in the kit

Every backend feature comes with a finished Svelte UI: pages, dialogs, forms and toasts.

Authentication

Login, registration, password reset, email verification, two-factor auth, passkeys and profile & security settings. You switch each one on or off per domain.

Multi-tenancy

Each tenant gets its own database and subdomain. You create and edit tenants from a list with stats, track workspace status and invite each tenant's admin.

Domains

Give each tenant a primary domain and as many secondary ones as you need. Every domain has its own app name, default language and sign-in options.

Maintenance & suspension

Put every tenant workspace into maintenance with your own message, a secret bypass link and allowed IPs. You can also suspend a single workspace, which blocks it.

Users & invitations

Manage users with search and stats, give them a role and extra permissions, and invite them by email with a signed link.

Roles & permissions

Spatie roles and permissions with protected system roles, separate permission config files for the central and tenant apps, and menus that respect them.

Navigation & layouts

Menus live in the database and you reorder them by drag & drop. Pick a sidebar or header layout, a sidebar style, a sign-in layout and light or dark mode.

Localization

17 languages. Each user picks their own, each domain has a default, and validation messages are translated and shared with the frontend.

Testing & tooling

Pest feature tests, Larastan, Pint, ESLint and Prettier are set up, along with Laravel Boost guidelines and skills for AI coding agents.

Conventions

Idiomatic Svelte

The Svelte kit sticks to the usual Svelte conventions, and svelte-check checks the types.

Pages
resources/js/pages/tenants/Index.svelte
Components
PascalCase .svelte files
Shared logic
resources/js/lib/*.ts and *.svelte.ts

Translations in a component

import { svelteLang } from '@erag/lang-sync-inertia/svelte'

const { __ } = svelteLang()

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

Typed routes with Wayfinder

import { index } from '@/routes/tenants'

index.url()

Framework-specific implementation

Svelte 5 runes for focused page state

The Svelte kit uses runes for page state and shared .svelte.ts modules for behavior, while Laravel and Inertia continue to handle routing, validation and authorization.

  • Read Inertia page data with $props and derive filtered results with $derived.
  • Use $effect for debounced visits and put reusable permission or layout state in .svelte.ts modules.
  • Expose modal actions with bind:this and keep accessible controls in shadcn-svelte components.

A page in Svelte

<script lang="ts">
let { tenants }: { tenants: Tenant[] } = $props();
let query = $state('');
let filtered = $derived(
    tenants.filter((tenant) => tenant.name.includes(query)),
);
</script>

See the complete Svelte implementation guide, including pages, layouts and daily development.

Shared backend

  • Weekly updates, pushed to that repository
  • Pest feature tests, with Larastan and Pint already set up
  • 17 languages, with translations synced to the frontend
  • Documentation for the backend and the Svelte frontend
