Most SaaS boilerplates give you auth and billing — then leave you to build multi-tenant teams from scratch. TeamKit ships with everything wired up: • Multi-tenant teams — create, invite by link, role-based access • Supabase RLS—row-level security scoped to team membership • Owner-pays billing—one Pro plan covers the whole team • Stripe subscriptions+Customer Portal • Next.js App Router, TypeScript strict, Tailwind CSS 4 • English & Japanese UI $79 one-time. No seat fees. Unlimited projects.

Hey PH! 👋 I'm the maker of TeamKit. I built this after spending weeks adding multi-tenant team features to every SaaS project I started. Auth and billing are solved problems — but inviting users, scoping data with RLS, and wiring up "owner-pays" billing always took me 2–3 weeks of boilerplate work. So I built TeamKit: a Next.js 16 starter where teams are a first-class citizen from day one. What makes it different from ShipFast or other starters: - Real team invites (link-based, no email required for local testing) - Supabase RLS policies that actually enforce team membership - Owner-pays model — one Pro subscription unlocks Pro for the whole team - Step-by-step setup guide inside the dashboard It's $79 one-time. Happy to answer any questions about the architecture or how I use Supabase RLS under the hood! 🙏
