conForm / Compare / Web3Forms
A privacy-first Web3Forms alternative
Web3Forms got the core idea right: paste a form action, get email, no account dashboard to babysit. conForm keeps that simplicity and changes what happens behind the endpoint. We only claim differences you can verify — our side against the open-source engine, theirs against their published materials.
| conForm | Web3Forms | |
|---|---|---|
| Setup | Email + form name → permanent endpoint. No account. | Email → access key. No account for the basics. |
| Submission storage | Never stored — content exists in Worker memory only during delivery (how, exactly). | Retains submissions per their published plans (30 days free / 1 year pro, per centrst/conform#28, checked 2026-07-23). |
| Source code | Open source (MIT); the hosted service reports the exact commit it runs. | Proprietary hosted service. |
| Exit path | Self-host the identical Worker in your own Cloudflare account. | None published. |
| Destinations at rest | AES-GCM encrypted; the alias is the only plaintext customer value. | Not documented. |
| Machine contract | Served OpenAPI, stable error codes with retryability, idempotent provisioning, next_action guidance, MCP server. | Human-oriented docs. |
| Webhooks | Signed (Standard Webhooks), email verification always the trust root. | Offered on paid plans per their site. |
| Test without noise | _test submissions: real delivery, [Test] subject, machine-checkable proof. | — |
Competitor descriptions reflect their public materials as recorded in our claims research (issue centrst/conform#28); if something above is out of date, tell us and we'll fix it.
What's deliberately the same
Ordinary HTML, a hidden honeypot field, reserved fields like _subject and _redirect, and your inbox as the destination. Migrating is changing one action URL.

Create an endpoint on the landing page — the whole flow is one form and one verification click.
