Launch a commercial AI SaaS without rebuilding the basics
NimBuild packages the production pieces teams usually wire by hand: Firebase authentication, Stripe subscriptions, credit accounting, AI workflows, admin tools, docs, marketing pages, and bilingual routing.
A documented stack, not a mystery box
The homepage now reflects the same architecture documented under content/docs, so buyers can see what they are actually getting.
Framework
Next.js 16 + React 19
App Router, localized routes, marketing pages, docs, protected user console, admin screens, and route handlers are already structured.
Auth
Firebase Auth
Google sign-in uses Firebase client tokens, HttpOnly server sessions, local user sync, protected routes, and admin authorization.
Data
PostgreSQL + Drizzle
The database schema supports users, subscriptions, payments, credits, generation history, and auditable ledger records.
Payments
Stripe subscriptions
Checkout, webhook processing, subscription state, scheduled credit grants, and idempotent accounting are documented and ready to adapt.
AI
Volcengine AI workflows
AI tool routes and server workflows are built around provider adapters, credit costs, history persistence, and failure compensation.
Global
next-intl + Fumadocs
English and Chinese UI copy, SEO metadata, blog content, and product documentation are part of the starter instead of afterthoughts.
Built for the parts that make SaaS real
Most starters stop at a landing page. NimBuild includes the product flows you need after launch: accounts, payments, credits, AI usage, operations, and documentation.
AI workflows with product accounting
Volcengine-powered AI tools are wired with credit deduction, refund-on-failure compensation, and generation history so usage can become a real business model.
I want to generate an image of two people, fighting outside a bar. They fight to the core. Once they're done, they sit down and drink beer.
Certainly, I'm generating this picture for you in a while. BTW are you talking about THAT movie?
I don't know what you're talking about.
Are you sure?
Yes, I'm sure. But if you're generating that scene, make sure the fighters have clown shoes and rubber chickens instead of fists!
Affirmative, here's your image.
Auth, billing, and data already connected
Firebase Google sign-in, server sessions, PostgreSQL, Drizzle, Stripe subscriptions, and webhooks are organized into reusable modules.
Readable structure for AI-assisted teams
Routes stay thin, feature modules stay bounded, and docs explain the architecture so Cursor, Claude Code, and your team can make changes safely.

Operational screens from day one
Admin pages cover users, subscriptions, credit adjustment, and ledger history, giving you the controls a commercial SaaS needs after checkout.
AI usage workflows
Provider adapters, generation history, credit costs, and refund compensation are already wired for commercial AI features.
Stripe billing
Subscription checkout, webhooks, annual credit schedules, and payment records are designed for real revenue flows.
Firebase authentication
Google sign-in, HttpOnly server sessions, local user sync, route protection, and admin checks are ready to customize.
Deployable architecture
Vercel-friendly App Router structure, cron endpoints, environment docs, and clear module boundaries keep launch work predictable.
Typed product modules
Next.js 16, React 19, TypeScript, Tailwind CSS, Radix UI, and Framer Motion are organized for reuse.
Ledger-backed database
PostgreSQL and Drizzle track users, plans, credit buckets, ledger entries, payments, and generation history.
Marketing and docs
Landing pages, pricing, blog MDX, SEO metadata, legal pages, and Fumadocs documentation ship with the starter.
Agent-friendly codebase
Feature folders, server boundaries, support helpers, and docs make the project easier for AI coding tools to modify.
Built for founders who need a real product surface
NimBuild is positioned for developers, course builders, and AI SaaS founders who want to start past the boilerplate phase.
Start from a SaaS foundation you can sell
Clone the starter, connect your Firebase, Stripe, database, and AI provider keys, then spend your build time on the product only you can create.
