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.

Modules / Identity and access

Billing and access

Separate payment events from authorization decisions.

Web billing

The web application integrates Stripe billing, subscriptions, and entitlements. /billing is the web subscription surface. Configure the server-side Stripe keys, price ID, and webhook secret for your sandbox or deployed environment.

Authorize through entitlements

A checkout redirect is not evidence of active access. The server-owned entitlement decides whether a workspace can use a paid capability. Check that entitlement at the action boundary even when the interface already hides the action.

Verify the lifecycle

Use sandbox events to verify activation, updates, cancellation, and webhook handling. Keep repeated events safe and ensure an inactive entitlement blocks paid operations. Native mobile purchases remain a separate RevenueCat integration boundary.
