Taylor Built a Full Shopify Brand with AI in One Afternoon

Episode 071 – Taylor Built a Full Shopify Brand with AI in One Afternoon

Karl and Taylor compare how Claude, Codex, and Cursor behave differently when building Shopify discount and checkout UI extensions, and dig into why testing against a real dev store is still such a pain point.

Taylor also walks through spinning up a complete fictitious coffee shop brand, theme, and metaobject data model with Claude Design and Claude Code for his recent DEV conference talk on metaobjects, and shares how a Shopify theme store change quietly broke his Shop Info app.

Plus: a major new identity verification requirement for Shopify Partners requesting collaborator access, updates to app pricing limits and review policy, and this week's picks.
