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 / AI and operations

AI and background jobs

From an authorized request to a durable result.

Follow the task lifecycle

The production task API validates the authenticated workspace and entitlement before persisting a task and dispatching the ai.generate Trigger.dev workflow. The router applies capability requirements and configured model policy.

POST /api/ai/tasks
  → authenticated workspace + entitlement
  → durable task record
  → Trigger.dev ai.generate
  → model routing + generation
  → usage record + result
  → transactional completion delivery

Configure aliases and budgets

The user selects an enabled alias: cheap, fast, or smart. The server controls the underlying model IDs, provider credentials, workspace policy, and budget enforcement. Encrypted bring-your-own-key support must preserve the same server-only boundary.

Keep workflow semantics explicit

JobRunner promises enqueue, status, and cancel only. Trigger.dev workflow semantics are explicit, including durable execution behavior. Do not infer retries or scheduling guarantees from the generic contract.

The production submission path uses idempotency and saved task recovery to handle ambiguous dispatch. Completion of generation is separate from completion-email delivery.
