Getting started

Inspect your first element in under a minute.

CascadePeek starts only after you click the toolbar icon. Use it on normal web pages to inspect CSS, pin a result, copy useful snippets, and activate Pro when you have a license key.

1Install CascadePeek from the Chrome Web Store after approval, or use the packaged extension during private testing.

2Open a normal web page such as a product page, docs page, landing page, or local app.

3Click the CascadePeek toolbar icon, then hover an element to inspect its selector, size, CSS, and HTML.

4Pin an element, copy CSS or HTML, and use keyboard navigation to move through nearby elements.

Activate Pro

After purchase, Creem shows the license key on the order confirmation page and in the receipt email. Paste that key into the CascadePeek panel and press Activate. Pro unlocks authored rules, design token output, CSS variable copy, in-page editing, component bundle copy, AI prompt copy, page design brief copy, and DESIGN.md copy.

Pages where Chrome blocks extensions

Chrome extensions cannot run on Chrome Web Store pages, browser settings pages, or other restricted browser URLs. If CascadePeek does not appear, reload a normal website and click the toolbar icon again.

Need help?

The extension panel includes Setup guide and Support links. You can also use the support page or email testiebi90@gmail.com. For license issues, include your purchase email, the last 6 characters of the license key, and the exact error shown in the panel.
