At Callstack x Vercel AI SDK Meetup Michał Miszczyszyn explains how Your Next Store builds AI-generated commerce storefronts that connect to real backend flows instead of stopping at visual mockups.
In this talk, he walks through the architecture behind the system, including Vercel Sandbox, AI Gateway, Claude Agent SDK, WebSockets, Git-based persistence, and Next.js running inside a live sandboxed environment.
You’ll hear about:
- why general AI builders break when real commerce logic enters the flow
- how a sandbox is created, bootstrapped, and reused during storefront generation
- why WebSockets are central to the chat and live update experience
- how repository pushes and deployment fit into the editing workflow
- where costs, sandbox lifecycle management, and security become hard engineering problems
The session also covers the trade-offs behind keeping the AI agent bounded to an e-commerce context, tracking token costs across providers with AI Gateway, and limiting what the agent can modify inside the sandbox.
