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 / Getting started

Run the mobile app

Connect Expo to a reachable development API.

Setup and configuration

Install the workspace dependencies first. Set EXPO_PUBLIC_API_URL to an API origin reachable by your simulator or phone and EXPO_PUBLIC_APP_SCHEME to the app scheme. Start the web API before testing authenticated native flows.

pnpm --filter @starterkit/mobile start
pnpm --filter @starterkit/mobile android
pnpm --filter @starterkit/mobile ios

Implementation workflow

Use the platform command supported by your host; the iOS simulator requires an appropriate macOS development environment. A phone's localhost refers to the phone, not your development computer. Confirm network reachability when the app cannot contact the API.

Review apps/mobile/app.config.ts before testing deep links. Public Expo variables are bundled into the client and must never include database, billing, authentication signing, or AI-provider secrets.

Verification and troubleshooting

Verify API reachability, sign-in, returning to the app, session restoration, and sign-out. Test both a fresh installation and a returning session. A desktop browser preview is not native-device acceptance.
