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.

Trigger.dev jobs

Keep durable workflow behavior explicit.

Setup and configuration

Set JOB_PROVIDER=trigger with server-only TRIGGER_SECRET_KEY and TRIGGER_PROJECT_REF for production task submission. Review apps/web/trigger.config.ts and the ai.generate task in apps/web/trigger before configuring the target project.

JOB_PROVIDER=trigger
TRIGGER_PROJECT_REF=your-project-reference
# Provide TRIGGER_SECRET_KEY through the server secret store.

Implementation workflow

The shared JobRunner contract promises enqueue, status, and cancel. Trigger.dev owns workflow-specific semantics; do not infer scheduling, retries, or durability guarantees from the generic interface.

The durable application task ID connects dispatch, worker execution, usage records, and results. A failed provider-run metadata attachment after confirmed enqueue must not cause another enqueue or invalidate accepted work.

Verification and troubleshooting

Verify the deployed task identifier and project match the configured environment. Separate enqueue acceptance from workflow completion and from email delivery. Read docs/production-ai-runtime.md for recovery and safe diagnostics before manually retrying work.
