Jamstack form

A Jamstack form is a form on a site built with the Jamstack architecture - pre-rendered static pages, enhanced with JavaScript, served without a traditional application server. Jamstack's premise is that you do not need a server for most of what a website does, but forms are the place that promise wobbles: a form has to POST somewhere.

The answer is a hosted form backend. The static form's action points at a form endpoint, and the backend receives the submission, filters spam, stores it, notifies you, and fires webhooks - all without you running or maintaining a server. This works identically across static-site generators and hosting providers, because the only contract is an HTTP POST.

This pattern keeps the site fast and cheap to host while still capturing leads and messages reliably. The forms guide covers embedding a form in any stack, and the Jamstack contact form walkthrough builds one end to end.
