Frequently asked questions

12 questions

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 Expo apps as starting points for web and mobile experiences.

What authentication is included?

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.

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: 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.

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.

Can mobile expose Stripe Checkout?

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

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.

Mobile / Development

Build and device verification

Separate a successful Expo export from release readiness.

Setup and configuration

The mobile workspace build invokes its export script. This validates bundling for the configured targets; store signing, distribution configuration, and physical-device acceptance remain separate work.

pnpm --filter @starterkit/mobile typecheck
pnpm --filter @starterkit/mobile test
pnpm --filter @starterkit/mobile build

Implementation workflow

Run shared contract tests after changing a package consumed by mobile. Review native safe areas, keyboard behavior, readable text sizing, and reduced motion on the devices you intend to support.

Keep native purchases behind the existing RevenueCat boundary. A successful bundle must not introduce Stripe Checkout into the mobile interface as a substitute for a verified native purchase integration.

Verification and troubleshooting

Record the device, build, API environment, and sign-in method used for acceptance. Verify deep-link return, session restoration, denied entitlements, and sign-out. Report export success separately from store and device verification.
