Formspree is a form backend, API and email service for HTML and JavaScript forms. Developers point their form's submit address at a Formspree endpoint, after which submissions are stored in an inbox and forwarded by email, so the website's own frontend code stays under the developer's control. The service is delivered as a hosted online service.
The website does not state the company's legal name or headquarters. Formspree states that its services are hosted with Amazon Web Services in the United States, without naming an AWS region or an EU option, and that it relies on Standard Contractual Clauses for transfers. It holds SOC 2 Type II certification and states that it is fully GDPR compliant. The software is not open source. For a European organisation, US hosting means that transfer safeguards and US jurisdiction should be assessed before use.
