What is the best TanStack Start SaaS boilerplate?
It depends on what your product needs beyond the web app. For a lean, web-only tool on Cloudflare Workers, TanStarter keeps hosting costs lowest. supastarter suits teams that want Hono and oRPC with five payment providers. supastack fits B2B and AI products: its TanStack Start app costs $149 one-time and includes team workspaces, eight payment providers, API keys, signed webhooks and 13 languages. You can add Next.js, Expo mobile and Tauri desktop apps that share the same backend.
The short answer
A TanStack Start SaaS boilerplate saves you the weeks between npm create and your first paying customer: sign-in, teams, billing, emails, and a deployment that works. Three starters offer TanStack Start today, and they suit different products.
- Pick supastack if you are building a B2B or AI product that needs team workspaces, API keys, webhooks and room to add mobile or desktop apps later.
- Pick supastarter if you want Hono and oRPC for your API layer and already know the supastarter conventions from its Next.js edition.
- Pick TanStarter if your product is a small web-only tool and near-zero hosting cost on Cloudflare Workers matters most.
What a TanStack Start boilerplate should include
TanStack Start gives you typed routes, route loaders, server functions and server rendering. It does not give you accounts, billing or tenant isolation. These are the parts to check before you buy any starter:
| What to check | Why it matters |
|---|---|
| Server functions that check the session and workspace role | Typed routes do not protect data; every server function must confirm who is calling |
| Payment webhooks on their own server routes | Providers retry deliveries, so each event must be verified and applied only once |
| Teams from the first commit | Adding organizations later means changing every table and permission check |
| A tested billing layer | Plan changes, seats and refunds are where generated code fails quietly |
| A deployment path that already works | TanStack Start runs on many hosts, but the starter should ship one you can use today |
| Written guides and agent instructions | TanStack Start has fewer examples online than Next.js, so docs fill the gap for you and your coding agent |

What you get with supastack's TanStack Start app
supastack's TanStack Start app is a full SaaS web app, not a demo. It sits on the same shared packages as the Next.js app, so sign-in, billing, the database and AI behave the same in both. Start with the five-minute quickstart to run it locally with fake providers and no accounts.
- Sign-in with email codes, passwords, magic links, social accounts, passkeys and two-factor authentication.
- Personal and team workspaces with invites, roles, per-seat billing and an admin area.
- Billing through any of eight providers, with one webhook flow that ignores repeat deliveries.
- An AI assistant with each workspace's own provider keys stored encrypted and spending kept within a budget.
- A versioned API with workspace API keys, outbound webhooks, an audit log and an OpenAPI reference for your customers.
- Background jobs, transactional email, sitemap and robots files, and 13 languages.
- Over 580 automated test files across the repository, plus

When another starter is the better fit
supastack is not the smallest option. If you are testing one idea alone and want the lowest monthly bill, TanStarter's single Cloudflare Workers app has far less code to read. If your team already ships supastarter on Next.js, its TanStack Start edition keeps the same habits.

Common questions about TanStack Start boilerplates
- Is TanStack Start ready for a paid SaaS product? — Yes for most teams. It is on stable 1.x releases, built on TanStack Router and Vite, and renders on the server. Its ecosystem is smaller than Next.js, so pick a starter with thorough guides.
- Do I need Cloudflare to run TanStack Start? — No. supastack's TanStack Start app runs as a Node server and ships a Dockerfile for container hosts such as Google Cloud Run. TanStarter targets Cloudflare Workers instead.
- Can I move between TanStack Start and Next.js later? — With supastack, both web apps share the same sign-in, billing, database and AI packages. Switching means porting screens and routes, not rewriting your backend.
- Do I have to buy the Next.js app as well? — No. The TanStack Start app is $149 on its own. Any two platforms cost $298, and all four (Next.js, TanStack Start, Expo and Tauri) cost $299. See [pricing](/pricing).
- Will coding agents handle a TanStack Start codebase? — They know Next.js better, so instructions matter more. supastack's
