#Next.js#SaaS#Clerk#Drizzle#Stripe#i18n#Multi-tenant#Boilerplate

Overview

The most feature-complete free SaaS boilerplate available. Handles everything a real SaaS product needs: multi-tenancy, role-based permissions, team management, billing, and internationalization — all integrated and production-tested.

Features

  • Multi-Tenant Architecture: Organization/workspace model with proper data isolation.
  • Roles & Permissions: Role-based access control (RBAC) with team-level permission scopes.
  • Clerk Auth: Enterprise-grade authentication with social logins, MFA, and organization management.
  • i18n: Full internationalization setup with next-intl and locale-aware routing.

Use Cases

  • Building a B2B SaaS product that needs team workspaces and role management.
  • Starting an internationalized product that targets multiple markets from day one.
  • Getting a complete billing + auth + database integration without writing boilerplate.

Technical Advantages

  • Drizzle ORM delivers type-safe SQL with minimal overhead.
  • Clerk handles auth complexity (SSO, MFA, org management) that would take weeks to build.
  • i18n from the start means you never have to retrofit it later.
