SaaS Starter (CMSaasStarter) is a free, MIT-licensed SvelteKit template from the team behind Kiln AI, which was itself built on it. It includes Supabase Auth with OAuth and email verification, Stripe Checkout subscriptions with a self-serve billing portal, an onboarding flow, user dashboard, pricing page, blog with RSS, backend-free site search and a contact form. Marketing pages are pre-rendered for 100/100 PageSpeed scores, and the suggested Supabase + Cloudflare stack is free to host at small scale.
