What should we build next?

supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so you can focus on product-specific features.

Yes. supastack includes Next.js and Expo apps as starting points for web and mobile experiences.

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.

supastack includes configurable multi-provider AI, usage tracking, budgets, and encrypted bring-your-own-key support.

For products built on the kit, Stripe billing, subscriptions, and entitlements form the paid-access foundation. Provider secrets stay server-only.

Product-specific features remain in a separate codebase while the product configures and integrates supastack’s foundation modules.

The kit is a one-time purchase with lifetime updates: One Platform at $249 (temporary launch price, $100 off the regular $349) — your pick of Next.js (Web), Expo (iOS & Android), or Tauri (macOS & Windows Desktop) — or the All Platforms Bundle at $499 (temporary launch price, $100 off the regular $599) with every platform 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.

User-owned records are scoped by workspaceId. Identity, entitlements, AI usage, billing events, and audit entries stay inside the personal workspace boundary.

Trigger.dev is the explicit job runtime. The JobRunner contract only promises enqueue, status, and cancel—workflow semantics stay Trigger.dev-specific and explicit.

Transactional email covers product workflows such as completion notices. Cold outreach and campaigns are product concerns outside this kit’s email module.

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.

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.

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.

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.
