Fullstack Guardian

This is for building web features that touch the entire stack, from database queries to UI components, with security baked into every layer. It forces you to think through frontend, backend, and security simultaneously rather than bolting protection on afterward. You get a structured workflow that runs a security checklist before you write any code, plus reference docs for common patterns like CRUD flows, REST APIs, and error handling. The three-perspective example format is genuinely helpful for keeping auth, input validation, and output encoding in sync across layers. Best for teams that keep shipping features with inconsistent security controls because different people own different parts of the stack.
