Every SaaS rebuilds the same boring-but-critical layer: authentication, organizations, billing, and an admin panel. Ship Kit gives you that layer done right for Next.js 16 + TypeScript, built on Better Auth.
You get email/password and social sign-in with two-layer route protection; organizations/teams with server-enforced roles and strict cross-org isolation; org-level Stripe subscriptions (checkout, customer portal, a signed replay-safe webhook, plan-gating); and an operator admin panel (user/org management, impersonation with audit log, metrics). Plus deterministic jscodeshift codemods that handle the mechanical part of migrating off NextAuth or Clerk โ an assist, not a one-click migrator; they leave greppable TODOs where a human decides.
It's strict-TypeScript, covered by 245 unit tests + Playwright E2E, and a nightly canary upgrades Better Auth and re-runs the suite so you stay current. $179 solo / $499 agency, one-time. 14-day refund. Independent, not affiliated with Better Auth.

BetterAuth.app's answer
Deterministic codemods that handle the mechanical part of migrating off NextAuth or Clerk โ most starters give you a fresh setup, but not a migration path. Plus a nightly canary that auto-upgrades Better Auth and re-runs 245 tests, so the kit stays current.
BetterAuth.app's answer
It ships the full boring-but-critical layer โ auth, organizations, org-level Stripe billing, and an admin panel โ server-authorized and covered by 245 tests, not just scaffolding. And it's built specifically on Better Auth for Next.js 16.
BetterAuth.app's answer
Solo founders and small teams building a multi-tenant SaaS on Next.js who want to skip rebuilding authentication, billing, and admin, and ship the actual product instead.
BetterAuth.app's answer
A solo developer who kept rebuilding the same auth + billing + admin layer for every project, and decided to build it once, properly tested, on Better Auth โ so others can ship faster.
BetterAuth.app's answer
Next.js 16, React 19, TypeScript, Better Auth, Drizzle ORM on Postgres, Stripe, Tailwind + shadcn/ui, Vitest + Playwright.
