Your platform, three steps
The buy button is a few lines of HTML, so it works anywhere a page accepts HTML. These guides walk the same three steps on every platform, with the menus, the file paths, and the traps called by name.
Choose your platform
The same three steps everywhere, just in different menus.
Astro
One tag in your layout head. No island needed.
Hugo
One line in baseof.html, plus one Goldmark setting.
Eleventy
Works in any template language you run.
Jekyll
Works on stock GitHub Pages.
Webflow
Paste custom code, then add an Embed element.
Carrd
One page becomes a store with two pastes.
Framer
An Embed component with a real size set.
Squarespace
Paste into Code Injection, then a Code Block.
Notion
Through a host like Super or Simple.ink, your Notion site takes the button.
WordPress
One Custom HTML block, no store plugin needed.
Ghost
Code injection plus an HTML card, beside Ghost memberships.
Plain HTML
No framework, no build. One tag, one block.
Not on this list?
WordPress, Ghost, and plain HTML all take the button the same way: paste the script tag once, paste the button where you sell. If your site lets you paste HTML, the answer is yes. The docs cover the general case.
