I'm using Un-static (https://un-static.com) as the form backend for my static site. It gives a form an HTTPS endpoint with no server code. Wire up the form on this page to Un-static. Set the form's action to https://forms.un-static.com/forms/YOUR_ENDPOINT_REFERENCE and method="post". I get YOUR_ENDPOINT_REFERENCE by registering the form at https://forms.un-static.com/register-form (ask me to paste mine). Rules: - Every field needs a "name" attribute. Include a field named "email" so I can reply to submissions. - Spam filtering and reCAPTCHA are handled by Un-static automatically, so a normal HTML POST needs no extra captcha or honeypot fields. - File uploads: add enctype="multipart/form-data" to the form and an <input type="file"> (paid plans). - No-reload submit: POST to the same URL with "/ajax" appended via fetch(). This requires the form to be linked to an account with your own reCAPTCHA. Send FormData (not JSON) if files are involved. - The post-submit redirect is configured in the Un-static dashboard, not in the markup. Machine-readable docs: https://un-static.com/llms.txt (append .md to any docs URL for raw markdown). Generate the form HTML now.

A form endpoint is the whole backend

why-us
We run static sites ourselves.
We are not just a form endpoint provider — we've been on the receiving end of scraped e-mail addresses and bot floods too.

spam
Your e-mail address is being hunted
We feel your pain
We have been targeted by spammers our entire lives as well. We hate spammers stealing e-mail addresses too. And we don't like bots either.
Stay off the spammer's list
Spammers constantly crawl the web for new e-mail addresses and online forms. It's illegal, but spammers don't follow the law — and once you're on a list, you never get removed.
Stop bots in their tracks
With Un-static forms your e-mail address never gets exposed, bots have a hard time sending automated messages, and you can focus on the messages that matter.
Receive messages today.
Register a form endpoint, add it to your form, and sit back and relax. It is simple.
