Formbox: self-hosted form submissions without Formspree

Static sites still need a place for contact forms to land. Formbox gives you an inbox URL — POST JSON or form-urlencoded, review submissions in a dashboard.

Features

• Create inboxes with a public POST /f/:id endpoint
• JSON or application/x-www-form-urlencoded
• Honeypot field _gotcha (spam discarded silently)
• Open CORS on the capture route (forms on other origins)
• Rate limits + size caps
• Docker one-command deploy

Quick start

git clone https://github.com/mamyan2001-gif/formbox.git
cd formbox
docker compose up --build
# → http://localhost:5100
