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/password, OTP, and social sign-in. 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 Framework at $249 or All Frameworks (Next.js, iOS, Android) at $499, plus $75 per extra developer seat. No kit subscription. Checkout on this site is not connected yet.

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.

Not yet. Mobile must not present Stripe Checkout until RevenueCat exists. Web can use Stripe for subscriptions and entitlements when billing is configured.

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.
