This is what you ship with supastack.
One purchase, four production stacks — a Next.js app, a TanStack Start app, an Expo app for iOS and Android, and a Tauri desktop shell. Auth, billing, AI, jobs and email already work; you keep the keys. This demo runs on the same surfaces the kit ships.
- Four stacks — Next.js, TanStack Start, Expo, Tauri
- 33 theme packs, 8 layouts
- Eight payment providers built-in
- Auth, AI, jobs and email wired

What's inside the kit.
Sixteen capability modules ship wired and documented — the same catalog the pricing page walks through.
Codebase
Next.js and Expo share TypeScript modules so agents and humans extend one codebase instead of forking surfaces.
Auth
Email, OTP, and social providers land in Better Auth sessions scoped to the user’s personal workspace.
Payments
Checkout, customer portal, and signed webhooks keep subscriptions and product access in sync. Swap Stripe for Paddle, Polar, or another adapter without rebuilding billing.
AI workflows
Route through OpenAI, Anthropic, or a compatible API with encrypted keys, usage tracking, and workspace budgets.
Jobs + email
Trigger.dev runs jobs through a narrow enqueue, status, and cancel contract. Transactional email stays separate from outreach.
Audit
Audit records, analytics hooks, and sanitized error context keep operational history attached to the right workspace.
Orgs
Invitations, membership boundaries, and a consistent workspaceId scope connect identity, data, and product access — for a solo space or a full organization.
Email
Transactional email belongs to product workflows, with provider adapters behind a shared interface—never mixed with outreach.
Key storage
Bring your own AI credentials without exposing provider secrets to the browser. Encryption stays server-side.
Usage budgets
Token tracking, model-aware estimates, and workspace budgets put consumption in context before spend runs away.
Analytics
An analytics interface carries event properties and workspace context while redacting sensitive values.
Error monitoring
Capture exceptions with workspace tags and sanitized context through the observability layer.
Comments
Threaded replies and member mentions, with workspace permissions.
Notifications
An in-app inbox, mobile push, and notification preferences.
File storage
Upload files to S3-compatible storage with workspace access.
API & CLI
Connect your app with a typed client and command-line tools.
Ship this as your own.
