Next.js SaaS boilerplate

A SaaS codebase your AI agent can extend—and you can still understand.

Frontend Accelerator is an AI-guided Next.js SaaS foundation for React-capable solo developers, technical founders, and freelancers. It gives you integrated patterns for authentication, billing, data access, protected routes, dashboards, content, and coding-agent workflows before you add product-specific features.

What you start with

  • Next.js 16 App Router, React 19, and strict TypeScript
  • Stripe and Lemon Squeezy payment adapters
  • Firestore and MongoDB database adapters
  • Google, GitHub, Facebook, and email magic-link authentication
  • Admin and member roles with server-protected administrator routes
  • Dashboard, blog, SEO, localization, email, and testing foundations
  • Project-specific instructions for Claude Code, Copilot, Cursor, Windsurf, and Agent Skills

When it is not the right fit

  • Organization or workspace-based multi-tenancy
  • Enterprise SSO, compliance certification, or fine-grained enterprise permissions
  • PostgreSQL or Supabase adapters without adding your own adapter
  • No-code development or autonomous deployment

Why start with a foundation instead of a blank repository?

Coding agents can generate individual features quickly. The harder work is keeping authentication, authorization, payments, database access, and dashboard behavior aligned through consistent boundaries, types, state transitions, and failure handling. Accelerator provides a working reference architecture while leaving you responsible for product-specific engineering, testing, monitoring, and security review.
