Builder Agent is a hosted AI agent that builds storefronts for you on Colossal Cloud. It uses Colossal Agent Skills with the Storefront SDK to make beautiful storefronts for your business. Describe the store you want in chat, and Builder Agent generates the code, applies a design from the library (or extracts a new one from a screenshot), wires up the Colossal backend, and launches it on Colossal Cloud. You don’t bring your own AI agent, API keys, or local toolchain.

When to use it

You want…Use
A store built and hosted for you, end-to-endBuilder Agent
To run the same skills inside Claude Code, Cursor, Codex, or another agent in your own repoAgent Skills
Builder Agent and Agent Skills produce equivalent storefronts — the difference is who runs the agent and where the code lives.

​
How it works

  1. You describe the store (brand, products, vibe, sections) in the dashboard chat, optionally attaching reference screenshots.
  2. Builder Agent picks or creates a design reference, scaffolds a storefront on top of the Storefront SDK, and seeds it with your products.
  3. The store deploys to Colossal Cloud on a *.colossal.store subdomain. Bring your own domain when you’re ready.
  4. Iterate by chatting — “make the hero darker”, “add a press section”, “swap the product grid for a carousel” — and Builder Agent edits the live store.
