saas-starter

Open-source SvelteKit + Convex SaaS template that gets harder to break the more agents work on it. Auth, billing, admin, AI chat, email, and i18n ship end to end. Every recurring bug class becomes an ESLint rule, banned-pattern check, test, or validator, enforced in CI. Deploy on Cloudflare or Vercel for $0. Maintained by stickerdaniel on GitHub, where it has earned 45 stars from the community.

It's actively developed around ai-chat, better-auth, bun, and is a solid reference for anyone building with these tools.
