Architecture
Supastarter
Supastarter is one of the cleaner Next.js + Supabase architectures on the market. Modular by design, with a clear separation between marketing and app, and a healthy update cadence. The Pro tier ships with i18n, organisations, billing, and an admin area.
Already CH Swiss-pinned
Same overall architecture intent — Next.js 15 + Supabase + Drizzle + shadcn/ui — but every default that's "global" in Supastarter is Swiss in Already CH. Hosting on Exoscale CH, Supabase self-hosted (not Cloud), Payrexx (not Stripe), Mistral (not Anthropic). The plumbing is identical; the providers are sovereign.
Data residency
Supastarter
Supabase Cloud (US-incorporated, EU regions available), Vercel global edge, Stripe in the US. For most products this is fine. For Swiss customers asking "where does our data live?", the honest answer is "Supabase picks a region, Vercel runs at the edge globally, and Stripe holds card data in the US."
Already CH CH 🇨🇭
Every default Swiss or European: Supabase self-hosted on Exoscale in Geneva or Zurich, Payrexx in Thun, Infomaniak in Geneva. The only US touchpoint is GitHub for code delivery — which we'll swap to a Swiss tarball for buyers who can't accept it.
Payment methods
Supastarter
Stripe covers the global card network plus Klarna, SEPA, and the usual local European wallets. Lemon Squeezy is an MoR option if you'd rather offload tax. Neither ships TWINT or PostFinance.
Already CH + TWINT
Payrexx ships TWINT, PostFinance, Swiss cards, Visa/Mastercard/AmEx, and Apple Pay / Google Pay. Settlement in CHF directly to a Swiss bank. 8.1% VAT pre-calculated in config/billing.ts.
Compliance posture
Supastarter
Ships GDPR-compliant data export and deletion endpoints and a generic privacy template. Good baseline for the EU market. nFADP-specific work (Art. 12 register, Art. 19 information, FDPIC-recognised SCCs) is on you.
Already CH nFADP
Ships the nFADP register at /admin/data-register pre-aligned to Art. 12, a privacy policy referencing nFADP Art. 19 + Art. 25, and FDPIC-recognised SCC wording for the GitHub transfer. Matomo cookie-free means no consent banner. Designed to pass a Swiss DPO's audit on day 1.

The honest comparison
Supastarter is one of the genuinely better Next.js + Supabase starters on the market — well-architected, well-maintained, fair pricing. If you're selling globally and Supabase Cloud + Vercel work for you, it's a strong choice.
Already CH is for the Swiss B2B case where the provider list matters more than the framework. Same overall architecture; every infrastructure provider replaced with a Swiss or European equivalent; nFADP register and Matomo cookie-free out of the box. If your buyers ask where data lives, Already CH removes a week of integration work.
