conForm / Compare / Formspree
An open-source Formspree alternative
Formspree is a full product: accounts, a submissions inbox, integrations, plans. conForm is deliberately less — a delivery primitive. If what you actually want is "my HTML form reaches my email," the smaller tool has real advantages, and every claim below is verifiable.
| conForm | Formspree | |
|---|---|---|
| Account | None. Email + form name → permanent endpoint. | Account-based product per their site. |
| Where submissions live | Your inbox only — nothing stored server-side (the exact data path). | A hosted submissions inbox is the core product; retention varies by plan per their published materials. |
| Source & exit | MIT engine; self-host the identical Worker anytime. | Proprietary hosted service (an earlier open-source variant is not the hosted product). |
| Automation contract | OpenAPI served by the API, stable error codes, idempotent provisioning, MCP server, generated accessible form code per framework. | Docs and client libraries oriented at humans. |
| Webhooks | Signed (Standard Webhooks) with email verification as the trust root. | Available per plan, per their site. |
| Price of the core flow | Free: 250 deliveries per inbox per month, shared across all its forms. | Free tier with plan limits per their pricing page. |

When Formspree is the better fit
If you want a searchable submissions archive, team workflows, or built-in integrations, you want a form manager — that's their product, on purpose. conForm never builds a second inbox: that absence is the feature.
