Could you build this?
Partial The front-end chat interface, live preview iframe, and code editor are straightforward to vibe-code, but providing a full multi-tenant isolated cloud runtime with serverless execution, databases, and instant hosting requires complex cloud infrastructure engineering.
What it would actually take: To build an AI app builder like Puter's, you need a Next.js or React frontend paired with an LLM orchestration layer (e.g. Anthropic/OpenAI APIs using streaming and tool calling). The core hard problem is sandbox isolation and code execution: running arbitrary generated code securely requires a microVM infrastructure like Firecracker, WebContainers, or hardened Docker containers, plus dynamic sub-domain routing (e.g., via Cloudflare Workers or Traefik) and persistent virtual file system state.
