Passwordless auth
Email one-time-code sign-in, sessions, and signed tokens — rate-limited and bot-protected with Turnstile out of the box.
Production SaaS boilerplate
Buy the SaaS. Build the idea.
LaunchSoku is a done-for-you production app. Auth, billing, a credit system, AI usage metering, an MCP server, affiliates, and an admin console are already built and wired together. You inherit a real SaaS — then add the one thing that makes it yours.

Everything included
Every feature you'd build first, already built
LaunchSoku isn't a starter template with a login page. It's a working SaaS — billing, credits, AI metering, an MCP server, affiliates, and an admin console, all wired together and ready to sell.
Multi-tenant teams
Workspaces with owner, admin, editor, and viewer roles. Every record is scoped to a workspace, and users can belong to many.
Stripe billing
Subscription tiers, hosted checkout, the customer portal, and webhook handling already wired to your database.
Credit & token system
A real usage ledger with reservations, monthly resets, and hard limits — so you can charge for anything that costs you money.
AI usage metering
Deduct credits per AI call automatically. Change what each operation costs from an admin screen, with no redeploy.
MCP server
A Model Context Protocol server with OAuth 2.1 so Claude and other agents can securely act on your users' data.
API keys
Hashed, revocable API keys with last-used tracking, so your customers can build on top of your product.
Affiliate program
Referral links, tracking, and payouts wired in — turn your happiest users into a sales channel.
Transactional email
Branded, deliverable email through Resend — from login codes to product notifications.
Admin console
Super-admin screens to tune operation costs, inspect API endpoints, and keep an eye on system health.
Observability & analytics
Sentry error tracking and PostHog product analytics, instrumented across the whole stack from day one.
CRM sync
Push new signups and customers straight into HubSpot — no glue code to write.
Build vs. buy
Everything here is months you don't spend
The same hard problems sit under every SaaS. Solve them once, slowly — or start with them already solved.
From scratch
Weeks of plumbing before your first real feature
- Wire Stripe subscriptions, webhooks, and the customer portal
- Design a credit ledger that never double-charges
- Meter AI usage without leaking money on every call
- Stand up an OAuth 2.1 server for MCP and API access
- Passwordless auth, sessions, rate limits, and bot protection
- Multi-tenant teams, roles, and data isolation
- Admin tools, affiliate tracking, CRM sync, and error reporting
Roughly three months of setup — before you build the thing people actually pay for.

Clone it, add your keys, and spend your time on what makes your product different.
Under the hood
A real backend, not a scaffold
Every SaaS needs the same core: accounts, teams, payments, usage limits, AI metering, and error reporting. LaunchSoku ships all of it as working code — typed end to end, tested, and ready to deploy.
See everything included
Auth & tenancy
Accounts, teams, and roles — already solved
Passwordless sign-in, sessions, and workspace-scoped data ship on day one. Owner, admin, editor, and viewer roles are enforced everywhere, and every sensitive route is rate-limited and bot-protected.
Billing & credits
Charge for your product from the first signup
Stripe tiers, checkout, and the customer portal are wired to a real credit ledger. Meter AI and any other costly operation per use, set limits per plan, and tune prices from an admin screen without a deploy.
AI & MCP
Agent-ready, with metering built in
Your AI endpoints deduct credits automatically, so usage can never outrun the bill. A built-in MCP server with OAuth 2.1 lets Claude and other agents act on your users' data securely.
Growth & connections
Grow the app without extra plumbing
A built-in affiliate program turns users into a sales channel, CRM sync pushes signups straight to HubSpot, and revocable API keys let customers build on top of what you ship.
The stack
You inherit the whole production stack
Every tool below is already chosen, wired, and paid for in engineering time. Three layers: the infrastructure that runs it, the surface your users touch, and the intelligence that grows it.
Infra
The tools that run it
The backend that powers everything behind the scenes — AI models, background jobs, the API, database, security, and hosting — plus the error tracking, tests, and CI that keep it production-ready.
Temporal
User Facing
The parts your users see
Everything your customers actually touch: the marketing site and app, sign-in, payments, and the emails they receive.
Marketing & Sales Intelligence
How you find and keep customers
Turn signups into revenue: product analytics show what people do, affiliates bring new customers in, and CRM sync pushes every lead and account into your sales tools.
FAQ
What you're actually buying
What exactly do I get?
The full source of a production SaaS: a Next.js web app, a NestJS API, a standalone MCP server, this marketing site, and the shared packages that tie them together. Auth, billing, credits, AI metering, affiliates, and the admin console are all built and working.
Is it really production-ready?
Yes. Everything is typed end to end with strict TypeScript, tested with Playwright and Vitest, instrumented with Sentry and PostHog, and set up to deploy to Vercel and Railway with CI/CD already configured.
What's the stack?
Next.js and NestJS on TypeScript, Prisma against Neon Postgres, Better Auth for accounts, Stripe for billing, Redis for rate limiting, and Resend for email — all in a Turbo monorepo.
Can I use my own AI models?
Absolutely. The credit and metering layer is model-agnostic. Drop in OpenAI, Anthropic, or your own endpoint behind the same interface and every call is metered automatically.
Do I own the code?
You get the full source under a commercial license and build your product on top of it. No runtime lock-in and no per-seat platform fees — it's your app.
How fast can I launch?
The months of boilerplate every SaaS needs are already done. Clone the repo, add your own keys, rename things, and you're building your actual product the same day.
