Site builders and hosts
Squarespace, Webflow, Framer, Wix, GitHub Pages, and the rest.
There is no per-platform integration to install, and that is the point: the endpoint is a plain HTML form post, so anywhere you can put markup, you can put a form.
If the platform lets you embed HTML
Webflow, Squarespace, Wix, Carrd, Framer and most landing-page builders have an embed or custom-code block. Paste the form from the Quickstart into it and you are done. Some builders own the <form> element themselves — in those, point their form action at the endpoint and add the access key as a hidden field.
If you generate a static site
Hugo, Jekyll, Eleventy, Astro, Gatsby and friends all just emit HTML. Drop the form into a template or partial; nothing about the build changes. The framework guides cover the ones where a component-level example helps.
If you are picking a host
It makes no difference. Vercel, Netlify, Cloudflare Pages, GitHub Pages, S3, a VPS — the form posts from the visitor's browser to us, so your host never sees it and needs no server-side runtime.
