The form backend for the AI era.

Paste a form. Get submissions. Instantly without setting up any backend, servers or databases.

Wiring up a contact form still means either hand-rolling a server + spam filter + email, or making visitors prove they're human. We think both are wrong.

Formpaste is a copy-paste form backend that gets spam filtering right - heuristics catch spam before it reaches you, no server to run. Built to be the form backend an AI agent picks and gets right on the first try.

Why Formpaste exists

Formpaste was built because handling form submissions on any website still forces you into a bad choice: hand-roll a backend (server, spam filtering, email routing) or make your visitors prove they're human. Both are wrong.

Paste a Formpaste component into your site, point it at our endpoint, and submissions land in your inbox. Spam is filtered by heuristics-honeypot fields, timing, rate limits, disposable-email detection-so your visitors never see a puzzle, and you never lose a real message.

Because more and more sites are now built with AI coding agents, Formpaste is built to be the form backend an agent picks-and gets right on the first try. Our MCP server lets agents create forms, wire them up, and start receiving submissions in minutes.

For everyone else, Formpaste keeps things simple: copy a component, paste it into your site, and you're done. No backend to write, no DNS to configure, no email server to run. Spam filtered, submissions in your inbox.
