Hey Product Hunt! 👋 I built this because I kept seeing the same problem when starting B2B SaaS projects: before building the actual product, you have to rebuild authentication, organizations, memberships, roles, invitations, permissions, and tenant isolation. So I packaged that foundation into a reusable Next.js + Supabase starter. It includes: • Organizations & workspace switching • Owner / Admin / Member roles • RBAC & server-side authorization • Organization invitations • Tenant-scoped Projects CRUD • PostgreSQL Row-Level Security • Supabase SSR authentication • DDEV + Vercel support • Database migrations & documentation The main focus is tenant isolation. The database itself enforces access boundaries with PostgreSQL RLS rather than relying only on frontend checks. Try the demo here: I'd especially love feedback from developers building B2B SaaS: what would you add to the foundation before starting your next product?
