Astro waitlist form
Build a waitlist page on your Astro site with zero JavaScript and no backend. A plain form in a .astro component posts to Formpaste, so signups land in your inbox. Perfect for a launch page on static hosting.
How to build it
- Create a form in your Formpaste dashboard and copy its access key.
- Copy the markup above into a .astro page or component.
- Replace YOUR_ACCESS_KEY_HERE with your access key, then build and deploy.

Astro gotchas
An Astro contact form is a plain form in a .astro component that posts to Formpaste. It ships zero JavaScript and works on a fully static build. You only reach for an island if you want an inline success message instead of a redirect.
Zero JavaScript by default
A form with action set to the Formpaste endpoint and method POST submits with a full-page post - no island, no client script. This is the whole point of Astro: the page stays static and fast.
No SSR required
Because the form posts to an external endpoint, you do not need Astro's SSR or an adapter. output stays static and the form works the same on any static host.
Islands only if you want inline JS
If you prefer to stay on the page and show your own success state, move the form into a framework island (client:load) and use the React or Vue onSubmit from the toggle. For a redirect-to-thank-you flow, no island is needed.
The hidden access_key wires it up
Keep the hidden access_key input exactly as generated. It tells Formpaste which form the submission belongs to.
What to get right
Show a success state
A waitlist signup should confirm instantly. Track state after the submit resolves and swap the form for a You are on the list message.
Referral position is optional
You can add a referral code field later, but do not block the core signup on it. Keep the first version to email plus name.
Deduplicate on your side
The same person may sign up twice. Treat email as the key when you export or sync the list.
How it works
Three simple steps for form submissions to land in your email inbox.
Create your form, set your form's action URL to Formpaste's endpoint, and add your access key.
