Introduction

SaasKitFy is a production-ready SaaS starter kit built with Laravel (backend API) and React + TypeScript (frontend SPA). It includes everything you need to launch a SaaS product — authentication, billing, multi-tenancy, RBAC, and a full admin panel.

Architecture

The project is split into three independent applications:

  • Backend (backend/) — Laravel REST API with Sanctum auth, Cashier billing, queues, and all business logic
  • Frontend (frontend/) — React + TypeScript SPA with TanStack Query, Zustand, and Shadcn UI
  • Marketing (marketing/) — Plain PHP marketing site with zero dependencies

Each app deploys independently, scales independently, and can be hosted on different servers.

What's Included

  • 5 auth methods — email/password, magic link, OAuth (Google, GitHub, Microsoft, Apple), MFA, SAML SSO
  • 5 payment gateways — Stripe, Paddle, MercadoPago, Lemon Squeezy, PayPal
  • 5 plan types — recurring, one-time, per-seat, metered, credits
  • Multi-tenancy — organization workspaces with data isolation, invitations, and custom roles
  • Admin panel — 14 controllers, 150+ configurable settings
  • API keys — scoped permissions, hashed storage, rate limiting
  • Webhooks — HMAC-signed delivery, event filtering, retry logic
  • Feature flags — percentage rollouts, user/org targeting
  • Audit logs — tracks every mutation with old/new diffs
  • Usage metering — custom metrics per org, daily series
  • Email templates — editable from admin, preview and test send
  • File uploads — S3/R2 compatible, signed URLs
