Frontend as product shell
Next.js is used as the polished product shell for the builder, documentation, onboarding, and future authenticated views.
Architecture
A split architecture for a serious workflow product.
Agent Zero separates the presentation layer from the orchestration layer so the builder can grow without turning the frontend into runtime infrastructure.
How the product is divided
This split is intentional: a fast, expressive frontend and a Python backend built for workflow execution.
Backend as orchestration layer
FastAPI exposes the content, contact, and future workflow runtime endpoints that the UI can call directly.
What comes next
The next product step is a real builder surface: draggable nodes, saved workflows, execution history, and authenticated workspaces tied to backend runtime APIs.
