What problem does it solve?
App Builder converts a user’s natural-language idea into a complete project plan and coordinated implementation workflow, avoiding manual technology selection, scaffolding, and cross-agent coordination.
Core Features & Use Cases
- Project type & template detection: Maps keywords (e.g., dashboard, payments, API) to the most suitable project template and scaffolding path.
- Tech stack selection: Chooses a default stack and alternatives aligned to the requested product type and constraints.
- Multi-agent execution orchestration: Coordinates a deterministic pipeline (planner → plan verification → database → backend → frontend → audits/tests → deployment), including the mandatory PLAN.md verification checkpoint.
Example use: A user requests “Build a SaaS app with subscriptions and webhooks,” and App Builder detects the SaaS pattern, selects the nextjs-saas template, produces an implementation plan, and orchestrates specialist agents to generate schema, endpoints/webhooks, UI flows, and deployment readiness.
