Custom Forms with No Server Code

The OG form backend for static sites. Founded in 2014 by Cole Krumbholz (who previously built Brace.io, acquired by Squarespace) and Rohit Datta (ex-Apple engineer), Formspree solved a problem as old as the web: collecting form submissions without a server. Point your HTML form to their endpoint, and submissions go straight to your inbox. No PHP, no backend, no fuss. Over 500,000 developers, agencies, and Fortune 500 companies use it. The service has evolved to include AJAX support, spam filtering, file uploads, integrations with Zapier/Slack/Airtable, and a React library for JS-heavy projects. Still bootstrapped, still shipping weekly improvements.
