Boilerplate-Stack

Next.js SaaS foundation

A Next.js SaaS boilerplate built as one production system

Boilerplate-Stack combines the layers a real SaaS needs inside one typed App Router codebase. Authentication, billing, account boundaries, AI, content, administration and operations follow the same conventions instead of arriving as disconnected examples.

Start with the foundation already joined up

  • Next.js 16 App Router and React 19 with strict TypeScript
  • Personal and workspace accounts with roles, invitations and RLS
  • Stripe billing, multi-LLM AI, CMS, jobs and admin dashboards
  • Docker, Coolify and Vercel-ready production configuration

What makes the foundation production-ready

01

One account boundary across every feature

Billing, credits, chat history, documents, API keys and team membership resolve through the same account model. A user switching workspace does not leave part of the application pointed at a different tenant.

02

Operational behavior ships with the UI

Rate limits, CSP, CSRF checks, error logging, background jobs, consent, data export and account deletion are part of the codebase. The starter covers how the product behaves after launch, not only how the landing page looks.

03

AI coding tools receive the project conventions

Claude Code, Codex, Cursor and AGENTS.md-compatible tools receive repository rules, specialist review agents and repeatable skills. Generated features can reuse the existing auth, billing, database and localization patterns from the first prompt.

Included in the codebase

  • Server-rendered localized marketing and application routes
  • B2C and B2B account modes from configuration
  • Admin, organization and private dashboard surfaces
  • Automated database, persona, accessibility and browser QA
