Is Shopify Theme Detector free to use?

Yes. Shopify Theme Detector is free, has no usage cap and does not require an account. There is no paid tier that unlocks extra output.

Does my data get uploaded to a server?

No. The tool is a JavaScript function that runs inside your browser tab. Nothing you paste or drop in is transmitted, logged or stored by us.

Do I need to create an account?

No account, no email address and no sign-in. Open the page and start working.

Does it work on a phone or tablet?

Yes. The interface is responsive and works in mobile Chrome, Safari, Edge, Firefox and Samsung Internet. You can also install Toolspea as an app from the browser menu.

Can I use the output commercially?

Yes. You keep every right you already had over the input, and we claim nothing over the output.

Does it work on headless Shopify stores?

Usually not. A headless storefront renders through its own framework and never publishes the Shopify.theme object.

Can I archive the storefront?

Website Cloner can download the public pages and assets for reference, subject to the store's terms.
