The Production-Ready Next.js SaaS Boilerplate to Ship Faster.

Auth, Stripe billing, multi-tenant teams, multi-LLM AI and i18n — wired end-to-end, typed and secured. And it ships with the rules and skills your AI coding agent needs to build features that actually fit.

Context is everything

Your AI agent is only as good as the codebase you point it at

Drop a generic starter into Claude Code and it guesses. Drop in Boilerplate-Stack and it already knows the architecture, the conventions and the patterns.

// agent without context

  • asks 10+ questions before the first line
  • ignores your folder structure
  • reinvents auth, billing and RLS
  • breaks conventions you fix by hand
  • hours lost re-explaining the project

Everything a SaaS needs. Already built.

Months of foundational engineering — done, typed, documented and ready to extend.

Multi-LLM AI + RAG

OpenAI, Claude and Gemini behind one interface. LangChain orchestration, SSE streaming, prompt caching, a multi-agent registry and a built-in knowledge base (PDF/TXT/MD) on pgvector + HNSW.

Enterprise security

OWASP-aligned: CSP headers, rate limiting, RLS policies, CSRF, input sanitization and Turnstile bot protection.

Auth & users

Supabase Auth, OAuth providers, magic links, onboarding flow and GDPR-compliant account deletion.

Stripe billing

Subscriptions, one-time payments, credit packs, multi-currency, customer portal, webhook automation and a built-in affiliate program.

Multi-tenant

B2C personal accounts or B2B workspaces with dynamic roles, permissions, invitations and account switching.

CMS & jobs

Multi-locale CMS with a WYSIWYG editor, media library, scheduled pg_cron jobs and a webhook handler dashboard.

i18n & email

URL-based locales (FR/EN), auto-detection, localized components and a pluggable email layer (Brevo, Mailjet).

Modern stack, production-ready

Next.js 16, React 19, strict TypeScript, Tailwind v4, shadcn/ui, Docker + Coolify, SEO and an installable PWA out of the box.

And 80+ more — all wired up81

AI Blueprint

Built for how you code now — with an agent in the loop

A first-class .claude/ workspace ships in the box. Your agent reads it and immediately works like a senior dev who has been on the team for months.

Your toolchain

Drop it into the AI tool you already use

This isn't a boilerplate you read — it's one your agent operates. The .claude/, AGENTS.md and .cursor/rules/ configs ship in the box, so any AI coding tool understands the codebase from the very first prompt.

Compatible with
  • Claude Code
  • Cursor
  • OpenAI Codex
  • Gemini CLI
  • GitHub Copilot
  • + any AGENTS.md agent
01

Clone & install

Grab the repo and install. The full agent workspace — rules, skills, subagents and hooks — comes with the code.

❯git clone … && npm install
02

Open in your AI tool

Open the folder in Claude Code, Cursor or Codex. The agent loads your conventions automatically — zero setup, zero priming.

❯claude
03

Ship by prompting

Describe the feature. The agent writes code that already respects your auth, billing, RLS and i18n patterns — on-pattern, not guessed.

❯add a team invites page
Same conventions, every tool — your AI writes code that fits the codebase.
Inside the box
