For AI SaaS Builders

Bunship is theAI SaaS starter kit for Next.js 16

Q: What is Bunship and who is it for?

Bunship is a production-ready AI SaaS starter kit for developers, indie hackers, and startup teams building paid web products with Next.js. It is designed for people who want to skip rebuilding the same launch infrastructure and move faster from idea to working product.

Q: Is Bunship an AI SaaS starter kit or a general Next.js boilerplate?

It is both, but opinionated toward AI SaaS and productized web apps. You get a modern Next.js 16 foundation plus the pieces AI and SaaS products usually need early: authentication, billing, queue or workflow patterns, admin surfaces, docs, reusable blocks, and i18n.

Q: What does Bunship include besides the UI?

Beyond the frontend, Bunship includes Better Auth or Clerk integration, Stripe or Creem billing flows, queue and workflow-oriented patterns, admin pages, docs surfaces, reusable product blocks, and multilingual routing. The goal is to cover the business and product infrastructure a paid SaaS actually needs.

Q: Does Bunship support Stripe, Creem, and subscription billing out of the box?

Yes. Bunship includes billing infrastructure for Stripe and Creem, including checkout flows, webhook handling, order state transitions, and subscription-oriented product logic. That makes it a better fit than a bare Next.js boilerplate with only a pricing page stub.

Q: Can I use Better Auth or Clerk for authentication?

Yes. Bunship is built to support Better Auth or Clerk, so you can choose the auth approach that best matches your team, product stage, and operational preference instead of forcing a single provider choice.

Q: Is Bunship a good ShipFast alternative?

If you want a more technical, modular starter with Bun, Turborepo, broader product surfaces, and clearer support for AI workflow scenarios, Bunship is a strong ShipFast alternative. It is aimed at builders who care about the implementation baseline, not just getting a landing page online.

Q: Can I use Bunship for non-AI SaaS products too?

Yes. The AI positioning reflects one of the strongest use cases, but Bunship also works for general SaaS products that need authentication, billing, admin, docs, reusable UI blocks, and a production-ready Next.js monorepo.

Q: What should I review before deciding if Bunship is the right Next.js SaaS boilerplate?

Review the docs, reusable blocks, feature pages, stacks pages, and pricing page. Those entry points show whether Bunship matches your expected architecture, coding style, billing setup, and launch workflow better than a generic starter kit.

Bunship is a production-ready Next.js AI SaaS boilerplate for developers, indie hackers, and startup teams. Launch with Better Auth or Clerk, Stripe or Creem billing, queue and workflow infrastructure, admin, docs, blocks, and i18n already wired.

Why Bunship

Built for paid AI SaaS, not just a polished demo

Most Next.js starter kits stop at UI and sign-in. Bunship covers the path from authentication to billing, async workflows, admin operations, docs, reusable blocks, and multilingual marketing pages.

12 core modules

Next.js 16 app foundation

Start from a modern App Router baseline instead of upgrading an outdated boilerplate before product work even begins.

Bun + Turborepo monorepo

Ship product app, docs, shared packages, and content from one workspace with faster local workflows and cleaner boundaries.

Auth that fits your stack

Use Better Auth or Clerk with practical flows for email, OAuth, sessions, and protected SaaS routes.

Billing for real products

Launch with Stripe or Creem billing, checkout, webhooks, order state handling, and the subscription lifecycle already wired.

Queue and workflow baseline

Use retry-safe async flows, cancellation paths, and operational guards for AI generation or other long-running jobs.

Reusable blocks and demos

Open live blocks, inspect implementation patterns, and reuse modules instead of rebuilding common product surfaces.

Admin and operations surfaces

Start with a practical baseline for admin pages, internal tools, tables, and product operations instead of stitching them later.

Docs and content entry points

Support product explanation and SEO growth with docs, features, stacks, and blog surfaces in the same system.

i18n-ready marketing pages

Publish English and Chinese routes from the same codebase and keep metadata, navigation, and content aligned.

Composable UI system

Build on shared components and patterns that feel like product code, not a throwaway landing page theme.

Database and infra hooks

Use Drizzle and production-minded integration points without reverse engineering the project structure yourself.

Faster path to paid launch

Spend time on product differentiation instead of rebuilding auth, payments, docs, and launch plumbing from scratch.

Cycle through model execution, queue governance, reusable block output, and release checks.
