Go live, onboard customers, and start generating revenue.
What's Included
The Building Blocks for Your SaaS
50+ production features. Built completely. Tested thoroughly. Ready to customize.
Self-Hosted Authentication
Own your authentication stack and user data. Better Auth runs entirely on your infrastructure—user data lives in your PostgreSQL, not third-party servers. No external API calls. No per-user fees. No vendor lock-in. Complete control.
Better AuthNext.jsTypeScriptPostgreSQL
- Email & password authentication
- Forgot password recovery
- Social login (Google, Facebook, etc.)
- Email verification (OTP)
- Two-factor authentication (2FA)
- 2FA backup & recovery codes
- Email change with confirmation
- Rate limiting & brute force Protection
Stripe Billing Integration
Start collecting payments on day one. The entire subscription lifecycle is already built and tested. You write zero webhook code. From checkout to renewal, your SaaS billing infrastructure is ready to go.

- Subscription checkout
- Webhook event processing
- Recurring billing
- Stripe customer portal
- Plan upgrades & downgrades
- Cancellation handling
- Pricing plans as code
Complete UI Foundation
Start with a responsive marketing site, dashboard shell, account settings, theme system, and accessible UI primitives. Apply your branding and build product-specific screens without reworking the foundation.

Internationalization (i18n)
Reach global customers with typed localization powered by next-intl, including localized routes, messages, and user interfaces.
Transactional Email
Build typed React Email templates and deliver them through your preferred provider or SMTP service.
Real-World Code Example
A complete reference SaaS demonstrates typed forms, validation, API calls, database access, and tests.
Developer Experience
The Codebase Built for Maintainability
Clean architecture, local-first development, and tooling that works out of the box.
Next.js App Router + React 19
Build full-stack applications in a single codebase with the latest React features.
TypeScript Everywhere
Write everything in one language from infrastructure to frontend. Less context switching, faster onboarding.
End-to-End Type Safety
Database, APIs, forms, queries, i18n, and components are fully typed.
Clean Architecture
Clear separation of concerns with dedicated layers to organize your code. Easy to navigate and customize.
Postgres + Drizzle ORM
A type-safe ORM that lets you query and migrate your database with confidence.
Drizzle Studio
Zero-config database browser. Explore and edit your data in a web interface.
Local-First Development
No Docker required. Local PostgreSQL & email testing. Works completely offline.
Bun
Lightning-fast package manager for quick dependency installation.
Forms & Validation
Shared validation schemas provide instant client feedback and enforce security on the server.
Type-Safe Env Vars
Fail fast on misconfigurations with typesafe environment variables.
Visual Studio Code
Pre-configured settings, tasks, debugging, and essential extensions.
Fully Customizable
Complete access to all source code. Adapt and extend everything to fit your needs and preferences.
Built for Humans & AI Agents
Generate more accurate code from Claude Code, Codex, Cursor, GitHub Copilot, and more with Agents.md
Documentation
Step-by-step guides for setup, configuration, and best practices.
UI Development
Build and test UI components in isolation with Storybook.
Continuously Evolving
6 years of active development since 2020. Battle-tested on real SaaS apps and updated constantly.

Infrastructure
Deploy Anywhere. Scale as You Grow.
Platform-agnostic architecture. Serverless infrastructure. No vendor lock-in.
Platform Agnostic
No vendor lock-in. Swap your database, email provider, or payment processor without rewriting application code. Your architecture stays portable.
Deploy Anywhere
Launch on Vercel, Netlify, Cloudflare, AWS Amplify, Railway, or your own infrastructure. Simply push your code and bring your SaaS application online.
Unlimited Environments
Create as many environments as you need—local, staging, production, or PR previews. Validate changes in production-like conditions before you merge.
Auto-Scaling
Scale effortlessly from zero to millions of requests. Infrastructure adapts automatically so you can focus on building, not managing servers.
Cost-Efficient
Pay only when requests hit your app. No traffic, no charges. Scale to zero and keep your costs exactly where they should be.
Infrastructure as Code
Define and provision services programmatically with version-controlled configuration.

You've Built This Before.
It Wasn't Fun.
Every SaaS project starts the same way. You spend weeks setting up authentication, wrestling with Stripe webhooks, and building account settings—and it ends up costing more than expected.
400 hours building code that doesn't differentiate your product.
By the time you've built the foundation, your competitors have already shipped. What if you could ship your first feature this week instead?
With Next.js Boilerplate Plus
Day 1: Build what matters
All that foundation work? Already done. Skip straight to building your product.
Skip the Setup. Build the Product.
Auth, billing, database, and dashboard are already wired. Get lifetime access, unlimited projects, and every future update.
