WordPress as our core SaaS application framework. Beyond traditional CMS use, we leverage WordPress's built-in user management, role-based permissions, frontend/backend architecture, and plugin ecosystem as modular microservices. This approach provides high-grade user authentication, extensible UI components, REST API capabilities, and multi-tenancy options - allowing our lean team to focus on business logic rather than rebuilding foundational systems. Perfect for solopreneurs who need to ship features quickly while maintaining scalability.
