TenantFlow is a production-grade multi-tenant SaaS platform designed to help organizations manage teams, users, and internal resources securely at scale.
The system is built with a clean separation of concerns, where the backend enforces authentication, authorization, and data isolation, and the frontend focuses on delivering a role-aware user experience.
- Multi-tenant architecture with strict organization-level data isolation
- Role-Based Access Control (Owner, Admin, Member)
- Secure authentication using JWT
- Centralized error handling and standardized API responses
- Modern frontend built with Next.js and TypeScript
