AG Shops is an independent guide from Actually Good Ideas. It is not made, sponsored or endorsed by Shopify. You need your own Shopify store and plan to use it.
You type what you want in plain words. The agent changes your theme on a hidden preview, checks it, and hands you a link. Nothing goes live until you say go.

It opens in your browser, works offline and remembers your progress. Flip the switch at the top to see every step for Claude Code or Codex.


four steps, no code
Install the Claude or Codex desktop app and point it at a folder for your store.
Paste one prompt. It installs the starter kit and Shopify's tools, and you approve each step.
Every edit goes to a hidden copy of your theme. Open the link on your phone and look.
Only then does it touch the live store, one changed file at a time. Your old theme stays as a one-click undo.
A kids' sensory-tools brand swapped an agency-built theme for a fresh one built on Shopify's free Dawn theme. One owner, one AI agent, every change on a preview first. About two weeks from first install to launch, fitted around running the business. This packet is that playbook, snags included.
Drag or click the image to compare. Before: an archived copy from the Internet Archive (October 2025), which doesn't load every font or the old logo, so it looks plainer than it did live. After: thecalmcaterpillar.com as it is today.


Full disclosure: The Calm Caterpillar was co-founded by Eric Elias, who made AG Shops. Every number here comes from the project's own logs and speed tests. Your results will depend on your store.
The Calm Caterpillar's rebuild was the kind of project agencies quote in the thousands. It was done by the owner and an AI agent in two part-time weeks. With AG Shops at $89 one time and a $20 AI plan, that's $109 to start. Every change after that costs a few minutes, not an invoice.
Two part-time weeks instead of a 4 to 12 week agency timeline. Small changes take minutes.
New banner at 10pm? Ask for it, check the preview on your phone, say go. No ticket, no waiting.
Stop paying someone to swap a photo or fix a typo. Put the budget into product and ads.
Your theme lives in your own GitHub, with plain-English notes. You own it, and anyone you hire later can pick it up.
Agency range from published 2026 Shopify design pricing, where custom builds commonly run $5,000 to $20,000 and bigger rebuilds more. AG Shops is $89, one time. AI plans as of November 2026: Claude Pro and ChatGPT Plus are $20 a month; heavier use may need a $100 to $200 plan. You still pay for your Shopify plan and any apps. Your costs and timing will depend on your store.
I co-founded The Calm Caterpillar. Our store ran on an agency-built theme, so I rebuilt it with an AI agent, part-time, in about two weeks. I wrote down every step, every snag and every prompt that worked.
That notebook became AG Shops. It's written for owners who don't code: you make the calls, the agent does the typing, and nothing goes live without your go.
rooting for you, Eric
