A simple cask for your form submissions

Formcask is a form backend for static sites and JAMstack apps. Paste one endpoint into your HTML. We store the message, email you, and (on Pro) POST a signed webhook with retries.

No server of your own

Works with plain HTML, Hugo, Astro, Eleventy, and anything that can POST.

Spam stays out of the way

Honeypot field plus per-form rate limits. Spam is stored separately and never emailed or sent to a webhook.

Built for client work

Workspaces group forms by client. The Pro plan unlocks webhooks, file uploads, and more than one workspace.

Copy-paste HTML

<form action="https://formcask.fly.dev/f/f_YOUR_FORM_ID" method="POST">
  <input type="text" name="name" required>
  <input type="email" name="email" required>
  <textarea name="message"></textarea>
  <input type="text" name="_gotcha" style="display:none" tabindex="-1" autocomplete="off">
  <button type="submit">Send</button>
</form>

Free plan: 250 submissions/month. Pro is $12/month, or $108/year.
