Contact forms for Astro

Add a contact form to your Astro site with zero JavaScript and no backend. It is a plain form in a .astro component that posts to Formpaste. Preview it live, copy the markup, and submissions land in your inbox - spam filtered automatically.

How to create a Astro form

1
Create a form in your Formpaste dashboard and copy its access key.
2
Copy the markup above into a .astro component or page.
3
Replace YOUR_ACCESS_KEY_HERE with your access key, then build and deploy.

Prompt for your AI coding agent

Give me a plain HTML contact form for an Astro component that POSTs to https://api.formpaste.com/submit with method POST and a hidden access_key input. No island, no client script, no backend.

Or connect the Formpaste MCP server to Claude Code, Codex, Cursor, Claude Desktop, VS Code, or any mcp-remote client. See the setup guide.

Zero JavaScript by default

The form above is a plain <form action> in a .astro component. It ships no JavaScript and submits with a full-page POST, then a redirect sends the visitor to your thank-you page. This is Astro’s whole point - the page stays static and fast, and the form still works.

An island only if you want inline JS

If you would rather stay on the page and show your own success message, move the form into a framework island (client:load) and use the React or Vue onSubmit from the toggle above. For a redirect-to-thank-you flow, you need no island at all.

Styling it to match your theme

The snippet is unstyled so it inherits your Astro theme. Switch the styling toggle to CSS or Tailwind for a starting point, or add your own classes - the field name attributes are all that matter to Formpaste.

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.

1

Create your form

Sign up, verify your email, and create an access key in your dashboard.

Copy the code

Paste the snippet above into your project. Pick CSS or Tailwind to match your site.
