conForm / Docs

A form backend for static websites

Your site is static — GitHub Pages, Netlify, Cloudflare Pages, an S3 bucket, a Vite build. You need a contact form that actually delivers. conForm is the missing backend: one POST creates a permanent endpoint, and submissions arrive in your inbox. No account, no server to run, no submission database anywhere.

Create an endpoint

curl https://api.conform.centrst.com/v1/routes \
  --request POST \
  --header 'Content-Type: application/json' \
  --data '{"email":"[email protected]","alias":"Contact"}'

The response contains your permanent endpoint. One human step remains: the destination inbox receives a verification email that must be confirmed before delivery starts. The endpoint URL never changes while pending, so you can install the form immediately.

Install it

<form action="https://api.conform.centrst.com/f/cfm_7K4P9X2M8RWD3JNH" method="post">
  <!-- your fields -->
  <button type="submit">Send</button>
</form>

Any ordinary HTML form works — no client library, no framework requirement. Ready-made accessible forms for every stack are one request away: see the recipes below or fetch them from the API directly.

Prove it works

curl -sS -X POST https://api.conform.centrst.com/f/cfm_7K4P9X2M8RWD3JNH \
  -d 'name=Test&[email protected]&message=Hello from a test&_test=true'

A _test submission is delivered for real with a [Test] subject, and the response answers test: true as machine-checkable proof.
