Loved byfounders worldwide.
I'm a marketer, not a full-time developer. Supastack brings auth, workspaces, billing, BYOK AI, email and themes together in one codebase. The AGENTS.md and prompts help me start building with Claude Code without learning every corner of the repo. Solid base for AI SaaS.bynikojuliuspnpm verify:local, the theme packs and the block library helped me restyle my whole marketing site quickly. The kit is easy to work with.
UniverseWhile building Skin Profile, I could see how auth, billing, jobs and the AI router are configured. It feels complete.

Start buildingI'm building Lixing, a local-first reflection app. I ran the monorepo on Windows and pulled four patterns into my app: config, secure license storage, entitlements and a paywall. The port passed 26 tests behind a feature flag before touching production. I don't need auth or billing today, but I know where to look when Lixing needs a backend.
PengGangjieI'm using Supastack for my app's backend now. I wish I'd had it from the start. It would have saved me even more work.
OpenMargin24I went through the repo in depth and ran the Rust tests. Few boilerplates ship a desktop option, so Supastack feels like a dream come true. The boundaries are written down and the code honors them — the desktop app never forks the web app's UI or auth.
Raven S.I'm not a coder, but Supastack's extensive documentation has taught me so much. I'm already building a landing page for my site, cutviee.com, even though I started with zero coding knowledge. It's truly beginner-friendly.

Built by a founder.Used to ship real products.
Hey, I’m Noah.
In 2024, I thought I could build something big. I launched a teacher-rating platform—and ended up getting a call from my director. That project is now closed, but I haven’t stopped shipping.
Over the past two years, I’ve tried dozens of projects: an AI image tool, an AI gateway, an AI learning app. Today, I’m still building LearnX, and I have plenty more ideas I want to try.
But every new idea came with the same first week: wiring up login, payments, emails, a database, and deployment. Before I could build the part I was excited about, I was rebuilding the same foundation.
So I built Supastack for myself: a boilerplate I could reuse whenever I wanted to start something new. Set up the foundation once, then spend my time on the idea.
Then I realized I couldn’t be the only one stuck doing this. If it helped me spend more time building, maybe it could help you too. That’s why I’m sharing it.
I’m still shipping. I just want the next idea to start with the idea, directly.
A few questions before you build.Answered.
What is supastack?
supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so you can focus on product-specific features.
Does it support web and mobile?
Yes. supastack includes Next.js and TanStack Start web apps plus an Expo app as starting points for web and mobile experiences.
What authentication is included?
Better Auth covers email OTP, magic-link, and social sign-in; email/password stays available at the API layer and through the Auth.js credentials engine for products that need it. Personal workspaces are provisioned with the account so product records stay scoped from day one.
How does it support AI?
supastack includes configurable multi-provider AI, usage tracking, budgets, and encrypted bring-your-own-key support.
How are subscriptions handled?
For products built on the kit, Stripe billing, subscriptions, and entitlements form the paid-access foundation. Provider secrets stay server-only.
Where does my product-specific code live?
Product-specific features remain in a separate codebase while the product configures and integrates supastack’s foundation modules.
How does supastack pricing work?
The kit is a one-time purchase with lifetime updates: Single Stack at $149 — your pick of Next.js (Web), TanStack Start (Web), Expo (iOS & Android), or Tauri (macOS & Windows Desktop) — Dual Stack at $298 with any two repos, or the Full Bundle at $299 with all four repos and the full monorepo, plus $75 per extra developer seat. No kit subscription. Checkout on this site delivers your license key by email, with repository access via GitHub invite.
How do workspaces scope my data?
User-owned records are scoped by workspaceId. Identity, entitlements, AI usage, billing events, and audit entries stay inside the personal workspace boundary.
How do background jobs work?
Trigger.dev is the explicit job runtime. The JobRunner contract only promises enqueue, status, and cancel—workflow semantics stay Trigger.dev-specific and explicit.
How is email different from outreach?
Transactional email covers product workflows such as completion notices. Cold outreach and campaigns are product concerns outside this kit’s email module.
How do mobile purchases work?
Mobile includes native purchases and restore through RevenueCat, with access verified by your server. Configure the store accounts and complete device testing before release. Web billing remains separate.
Where do AI provider keys live?
Bring-your-own-key credentials are encrypted and stay server-only. Keys are redacted from logs; usage and budgets remain visible at the workspace level.
Which payment methods does checkout accept?
The Stripe-hosted checkout accepts cards and can also offer Alipay and WeChat Pay once those wallets are enabled on the Stripe account — handy for buyers in China. Wallet authorizations confirm asynchronously, so the license page updates as soon as the payment clears.
Can I get a refund?
After you've got access to the repository, supastack is yours forever, so it cannot be refunded. But rest assured, you get the complete source code with lifetime updates to build and ship unlimited products for yourself or clients. You just cannot resell the code or redistribute the repository as a starter kit or template. One exception is the launch cashback — launch a live product built with supastack, share it, and reach 5,000 organic views or 50 organic likes within 60 days to get 50% of what you paid back; see the terms.
