App Builder

This is the entry point for building full-stack apps from scratch with Claude. It reads your request, picks a tech stack from 13 templates (Next.js SaaS, FastAPI, React Native, Chrome extensions, etc.), scaffolds the directory structure, then coordinates specialized agents to build frontend, backend, and database pieces. Think of it as the project manager that kicks off the whole process. The workflow is solid: detect project type, choose stack, create plan, delegate to agents. It's opinionated about 2025 defaults but supports alternatives. Best for greenfield projects where you want the entire scaffold handled, not for adding features to existing codebases where you'd use the feature-building flow instead.
