Formhook.app is an EU-hosted form backend for static websites. Generate one API key per form, paste it as your HTML form action, and start collecting submissions in minutes. No backend code, no server to maintain. Every submission lands in a clean dashboard, and you get notified instantly through the mobile PWA with push notifications or by email. The progressive web app installs on any phone, so contact requests reach you the moment they arrive, no app store needed. The free plan covers 5 forms and 250 submissions per month, enough to handle a contact form, a quote request, and a support inquiry on a typical small-business site. Hosting in the EU means submission data stays under EU data protection rules by default. Formhook is built for web studios and freelancers who ship static sites and want a reliable, low-overhead way to handle forms for clients who don't need a custom admin panel.
