The best open-source SaaS boilerplate in 2026. NestJS backend + Angular frontend with Stripe billing, multi-tenancy, RBAC, Docker, and Terraform. Free under MIT license — clone and ship your SaaS MVP in days.
Everything you need to get started — no configuration, no credit card, no learning curve.
Authentication with OAuth (Google, GitHub), magic links, and two-factor authentication (2FA)
Stripe subscription billing with usage-based metering, invoicing, and customer portal
Multi-tenant architecture with database-level data isolation per organization
Role-based access control (RBAC) with customizable roles and permissions per tenant
Email templates with Resend integration for transactional and marketing emails
Docker Compose, Terraform, and CI/CD configs for AWS and Vercel deployment
Admin dashboard with user management, subscription overview, and analytics
Comprehensive test suite with unit, integration, and E2E tests using Jest and Playwright
Get results in three simple steps — no account required.
Fork the repo and run the setup script. Docker Compose spins up PostgreSQL, Redis, and the full application. You are running locally in under 5 minutes.
Set your Stripe API keys, database URL, email provider (Resend), and OAuth credentials. Everything is configured via environment variables.
Focus on your unique features and business logic. Authentication, billing, multi-tenancy, and infrastructure are already built and tested.
Teams and individuals across industries rely on SaaS Starter Kit to solve real problems every day.
Founders launching a new SaaS product who want to skip 3-6 months of boilerplate development
Agencies building client SaaS products faster with a proven foundation
Enterprise teams standardizing their technology stack across multiple internal products
Hackathon teams shipping functional MVPs in 48 hours with real auth and payments
Solo developers who need production-grade infrastructure without a DevOps team
Yes. The SaaS Starter Kit is released under the MIT license. You can use it for personal and commercial projects without restrictions. Pro Support and Enterprise License plans are available for teams that want guaranteed support.
Backend: NestJS (Node.js) with TypeORM and PostgreSQL. Frontend: Angular with Tailwind CSS. Payments: Stripe. Email: Resend. Infrastructure: Docker, Terraform, GitHub Actions.
The backend is framework-agnostic — it exposes a REST API that any frontend can consume. Swapping Angular for React or Next.js requires only replacing the frontend directory. Community forks exist for React and Vue.
Multi-tenancy uses database-level isolation with schema-per-tenant for PostgreSQL. Each organization gets its own schema with shared application infrastructure. This approach balances data isolation with operational simplicity.
The starter kit includes configurations for Docker (any VPS), AWS (ECS + RDS via Terraform), and Vercel (frontend) + Railway (backend). You can deploy to any infrastructure that runs Docker containers.
ShipFast ($199-$299) and Supastarter ($349+) are Next.js-based boilerplates with Supabase backends. The Cloudrix SaaS Starter Kit uses NestJS for the backend and Angular for the frontend, providing enterprise-grade architecture patterns like dependency injection, schema-per-tenant multi-tenancy, and background job processing via BullMQ. It is free and open source under MIT license.
For teams that want a dedicated backend server (not serverless), enterprise-grade NestJS architecture, and zero vendor lock-in, the Cloudrix SaaS Starter Kit is one of the strongest options in 2026. It is especially well-suited for B2B SaaS products that need multi-tenancy, RBAC, and complex billing. For teams committed to the Next.js ecosystem, alternatives like MakerKit or Supastarter may be better fits.
Yes. Clone the repo, run Docker Compose, and you have a working application with auth, billing, multi-tenancy, and an admin dashboard in under 10 minutes. Focus your development time on your unique product features instead of rebuilding common SaaS infrastructure. Most teams save 3-6 months of development time.
Free Next.js starters typically use API routes for backend logic, which works for simple endpoints but lacks structure for complex business logic. The Cloudrix Starter Kit has a dedicated NestJS backend with dependency injection, modules, guards, and interceptors. It also includes Terraform deployment configs, CI/CD pipelines, and comprehensive test suites -- features rarely found in free starters.
