Launch Faster with Our Boilerplates
Production-ready, open-source starter templates built with modern tech stacks. Skip months of foundational work and start building your unique features from day one.
Why Use Our Boilerplates?
Skip Months of Setup
Authentication, multi-tenancy, billing, and database setup are already done. Focus on your unique business logic instead of infrastructure.
Production-Ready Code
Built with TypeScript, best practices, security considerations, and real-world patterns. Not toy examples, but battle-tested architecture.
Modern Tech Stack
Latest versions of Next.js, TypeScript, PostgreSQL, and other modern tools. Full-stack solutions with clear documentation.
Next.js Multi-Tenant SaaS Boilerplate
MIT LicenseA production-ready, full-stack SaaS starter built with Next.js 15, TypeScript, PostgreSQL, and Drizzle ORM. Everything you need to launch a B2B SaaS application with multi-tenancy, subscriptions, and RBAC.
What Problem Does It Solve?
Building SaaS applications typically requires months of foundational work around authentication, multi-tenancy, billing, and compliance. This boilerplate eliminates that overhead by providing pre-built systems for tenant isolation, user management, subscription tiers, and audit logging—allowing teams to focus on business logic instead of infrastructure.
Perfect For:
- B2B SaaS applications with multiple organizations
- Products requiring subscription-based billing
- Applications needing role-based access control
- Projects requiring complete data isolation between tenants
- Teams wanting to ship MVPs in weeks, not months
Key Features
Multi-Tenancy with Data Isolation
Complete row-level security and tenant isolation. Company/organization management with settings and user hierarchies.
Role-Based Access Control
Pre-built roles (ADMIN, MANAGER, STAFF, VIEWER) with granular permission system. Easy to extend with custom roles.
Subscription Management
Multiple tiers (FREE, BASIC, PRO, ENTERPRISE) with flexible billing periods. Payment tracking and subscription lifecycle handling.
JWT Authentication & 2FA
Secure JWT authentication with HTTP-only cookies. Optional two-factor authentication and email verification workflows.
