Formdall
Formdall
Formdall is the form backend for static sites. Instead of building your own endpoint, you change a single attribute: the action of your HTML form points at Formdall. No SDK, no npm install, no build step. We accept the submission, check it against a field schema you define per form, filter out the spam and store the rest encrypted. Then the notification goes out: email to you, auto-reply to the sender, HMAC-signed webhook to your system, or all of them. In the inbox you search submissions, export them as CSV and delete individual hits. Privacy is the architecture here, not a badge: hosted in Germany, AES-256 at rest, IP addresses kept only as a daily rotating hash, and a self-hosted proof-of-work captcha instead of reCAPTCHA - so no cookies, no cookie banner, no US transfer. Retention periods end in a daily physical deletion, not a soft delete. Formdall also speaks MCP: Claude, Codex, Cursor and any other MCP client create forms and write the finished snippet into your code.Starting Price: 4.99€/mo
