Nisuform catches every submission from your website’s forms, filters out spam and emails you the real ones in seconds. Claude Code, Cursor and v0 now build whole sites from a prompt, but their forms post to nowhere. Nisuform gives your agent one prompt with your endpoint and field names filled in, so it ships a working form. Free to start.

Hey Product Hunt 👋 I'm Han, the founder of Nisuform.
Every time I shipped a static site, the contact form was the one part that still needed a backend: a server, a database, a mailer and a spam filter, just to read three fields. Now that so many sites are built by Claude Code, Cursor or v0, it happens even more. The agent writes a beautiful form that posts to nowhere.
Nisuform is the backend for that form. Point any HTML form or fetch call at your Nisuform URL, and every real submission is saved to your dashboard and emailed to you within seconds.
A few things I cared about:
Your coding agent can do the setup. The Setup tab gives you a prompt with your endpoint and field names already filled in. Paste it into your agent and it builds the form in your site's style, or exactly as you designed it in the form builder. The docs are also published as llms.txt, and there's an MCP server, so you can ask Claude or Cursor to "create a waitlist form and add it to /launch" without opening the dashboard.
Spam protection needs no setup. Every plan runs a honeypot, a fill-time check and rate limits. Link-stuffed messages and duplicates go to a spam folder that never emails you and never counts toward your limit.
Your submissions stay yours. The free plan includes full history and CSV export, and nothing is deleted until you delete it.
Free is 3 forms and 100 submissions a month, no card needed. Pro is $10 a month for 5,000 submissions and unlimited forms, plus file uploads, auto-replies, analytics and delivery to Slack, Discord, Telegram, Google Sheets or a signed webhook.
I'd love honest feedback, especially if you try the prompt or the MCP server with your own agent. If it gets something wrong, I want to hear about it. I'm here all day to answer questions.
