SaasStinger

SaaSStinger Lite was created to solve a common SaaS development problem: rebuilding authentication, workspaces, memberships, roles, invitations, security rules, and other infrastructure for every new project. It provides a production-ready foundation developers can extend, while remaining compatible with Firebase's free Spark Plan so they can start building and validating without immediately requiring paid Firebase infrastructure.

SaaSStinger Lite is built with Next.js 16, React 19, TypeScript, Firebase Authentication, Cloud Firestore, Tailwind CSS, shadcn/ui, and pnpm. Its architecture includes multi-workspace memberships, OWNER/ADMIN/MEMBER roles, RBAC, invitations, audit logs, usage tracking, workspace settings, and secure Firestore rules. The foundation is designed to be extensible and Firebase Spark Plan compatible.
