ShipFast and supastarter both hand you a payment integration to configure. Spark Stack hands you a client kit and hosts the checkout, so no Stripe keys and no webhook plumbing ever enter your repository. That is the difference worth paying for, and at $199 it costs the same as ShipFast’s entry tier and less than supastarter’s.
It is the smallest of the three as well, and the table says where that costs you.
| Feature | Spark Stack | ShipFast | supastarter |
|---|---|---|---|
| Price | $199 one-time (list $399) | $199 Starter, $249 All-in (list $299 / $349) | $349 Solo, $799 Startup, $1,499 Agency |
| Stripe keys and webhooks in your repo | No, checkout is hosted by SparkPay | Yes, you wire Stripe or Lemon Squeezy yourself | Yes, you wire one of five providers yourself |
| Billing you get instead | Client kit: typed tier guards, plan limits, usage metering, trials, coupons, HMAC-verified webhooks, cached status hook | Payment integration code to configure | Billing package to configure, seat-based billing included |
| Multi-tenant organizations and seats | No | No | Yes, organizations, invites and roles modelled |
| Internationalization | No | No | Yes, locales, switcher and translatable mail |
| Auth | Google OAuth on NextAuth v5, with an email whitelist | Google OAuth and magic links | better-auth: password, passkeys, magic links, OAuth, 2FA |
| Database | Any Postgres (Neon, Supabase, RDS, local Docker) with Drizzle | MongoDB or Supabase | Choice of database with Prisma or Drizzle |
| Runtime and tooling | Bun, Turbopack, Biome, single app | Node, JavaScript and TypeScript, app and pages router | pnpm and Turborepo monorepo |
| Community | Email support from the person who wrote it | Discord with thousands of makers | Used by 1,516 developers per their own site |
Competitor pricing and features read from shipfa.st and supastarter.dev in November 2026. Both change their plans, so check theirs before deciding. ShipFast’s $199 and $249 are a launch promotion against $299 and $349 list.
It is the bigger product with the bigger community, and its Starter tier costs the same as Spark Stack does. If you want the pages router, plain JavaScript, or a Discord full of people who have already hit your problem, it is the safer buy at the same money. You will be wiring up Stripe yourself either way.
If you are building something multi-tenant, selling seats, or shipping in more than one language, buy supastarter and do not look back. Organizations, roles, seat billing and i18n are modelled from day one and Spark Stack has none of them. It starts at $349, against $199 here.
A single-tenant product, in English, that needs to charge money this week. The billing is already done rather than already started: hosted checkout means no payment keys in your repo, no webhook endpoint to secure, and no Stripe dashboard to learn before your first sale. $199 once, and it is yours for client work too.
