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.

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.
