HTML registration form

Build an HTML registration form with no backend. Copy the markup, collect sign-up details, and submissions land in your inbox or your own system - no server and no JavaScript required.

How to build it

Create a form in your Formpaste dashboard and copy its access key.
Copy the HTML above and paste it into your page.
Replace YOUR_ACCESS_KEY_HERE with your access key, then publish.

Prompt for your AI coding agent

Give me a plain HTML registration form with name, email, and password fields that POSTs to https://api.formpaste.com/submit with a hidden access_key input. No JavaScript, no backend. Note that this collects details only and is not an auth system.

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

HTML gotchas

A plain HTML form needs no framework and no JavaScript. Point the form's action at Formpaste, add a hidden access key, and the browser posts it for you. This is the simplest possible setup and works on any host.

No JavaScript required

A form with action set to the Formpaste endpoint and method POST submits on its own. You only add JavaScript if you want to stay on the page and show your own success message instead of a redirect.

Use a redirect for the thank-you page

Set a redirect URL in your form's dashboard settings and the browser lands the visitor on your thank-you page after posting. No script needed.

The hidden access_key wires it up

Every form needs the hidden access_key input. It tells Formpaste which form the submission belongs to. Keep it in the markup exactly as generated.

Style it however you like

The markup is yours, so any CSS works. Switch the styling toggle to CSS or Tailwind for a starting point, or add your own classes.

What to get right

Formpaste is a form backend, not an auth provider

A registration form collects details and emails them to you or forwards them to your system. It does not create login accounts or store passwords. For real authentication, wire the submission to your auth tool and never treat the form as a credential store.

Never email raw passwords

If you collect a password here, forward the submission to your own signup endpoint over a webhook rather than having it land in an inbox. Better still, capture only the details you need and let your auth provider set the password.

Validate on the client too

Match the two password fields and require an email format in the browser so people fix mistakes before they submit. Formpaste still filters spam on the server.

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.
