# supastarter Alternative: A Cross-Platform SaaS Starter with an Agency License

Looking for a supastarter alternative? supastack ships web, mobile and desktop in one tested monorepo — plus a license for unlimited client projects.

> **What is the best supastarter alternative in 2026?**
> It depends on what is missing for you. supastarter is a strong web-first starter for Next.js, Nuxt and TanStack Start. supastack is the leading alternative when you also need native Expo mobile (iOS/Android), Tauri desktop, a developer platform (API keys, signed webhooks, audit log), eight payment providers plus RevenueCat, a 144-file test suite, and a license that allows unlimited client commercial projects. For a pure Nuxt codebase, supastarter stays the better pick.

## Why Buyers Look for a supastarter Alternative

supastarter is one of the most established SaaS boilerplates: mature Next.js and Nuxt editions, Better Auth with organizations, five payment providers, i18n, and solid documentation. For a web-only SaaS it remains a safe choice.

Buyers start comparing alternatives when the roadmap asks for more: a native mobile app on the App Store and Google Play, a desktop companion, customer-facing API keys and webhooks, stricter AI cost controls, or an agency model where one purchase must cover many client builds.

- Cross-platform delivery: native iOS + Android apps and a signed Tauri desktop shell sharing one codebase, not a future rewrite.
- A real developer platform: workspace API keys, signed outbound webhooks, an audit log and OpenAPI for customer integrations.
- Economics that scale: unlimited client commercial projects under one license instead of paying again per product.


## supastack vs supastarter: Side by Side

Both are serious, agent-ready monorepos on Better Auth with organizations and lifetime licenses. The difference is surface area and platform depth.

| Capability | supastarter | supastack |
|---|---|---|
| Client surfaces | Next.js or Nuxt or TanStack Start (pick one edition) | Next.js 16 + TanStack Start + Expo mobile + Tauri desktop in one repo |
| ORM | Prisma or Drizzle | Drizzle |
| Billing | 5 web providers (Stripe, Lemon Squeezy, Polar, Creem, Dodo) | 8 web providers + RevenueCat for the app stores |
| Developer platform | Typed internal API (Hono/oRPC) | Workspace API keys, signed webhooks, audit log, OpenAPI |
| AI | Chatbot workflow to extend | Encrypted BYOK keys + usage budgets against a price catalog |
| Automated tests | Starter-level coverage | 144 test files + credential-free local verify gate |
| Client projects per license | Per license terms | Unlimited commercial client projects |
| Entry price | $349 Solo | $199 |


## Built for AI Agencies & Agentic Workflows (BMAD, Claude Code, Cursor)

A growing share of supastack buyers run AI software agencies on it. BMAD-style planning agents (Analyst, PM, Architect, QA) turn a client brief into scoped stories; Claude Code and Cursor implement them against a repository that already answers auth, billing, tenancy and testing; `AGENTS.md`, `.ai/` docs and Agent Skills keep every agent on the existing patterns.

Whether you hand a client a web MVP in five minutes from a single-platform repo, or deliver iOS, Android and desktop builds from the unified monorepo, one license lets you build unlimited commercial client projects — no per-project fee, one seat per developer who needs repository access.

- Single-platform repos for fast web-only client deliverables; the unified monorepo for iOS + Android + Desktop engagements
- AGENTS.md, .ai/ file docs and Agent Skills that keep BMAD, Claude Code and Cursor agents inside the architecture
- A credential-free local test gate that catches agent regressions before your client sees them
- One license, unlimited client projects — buy on a client's behalf and keep the margin on every engagement


## Who Should Pick Which

Pick supastarter if your product is web-only — especially on Nuxt — and you want the most established kit in this niche with a long public track record.

Pick supastack if you need mobile or desktop surfaces, customer-facing integrations, AI cost guardrails, a bigger test suite, or you run an agency billing multiple client builds off one license.

## Frequently Asked Questions About supastarter Alternatives

Straight answers for buyers comparing the two kits:

- Can I migrate from supastarter to supastack later?: Both use Better Auth and TypeScript end to end, so auth and domain models carry over conceptually; plan a data migration for Drizzle schemas and billing state rather than a file copy.
- Is supastack really cheaper for multiple products?: Yes — the entry tier starts at $199 and the license allows unlimited client commercial projects, so an agency buying once can ship every client engagement on it.
- Does supastack support Nuxt?: No. supastack's second web surface is TanStack Start on React; a Nuxt codebase is supastarter's unique strength.
