FormBridge

Forms without the backend

FormBridge

Overview

FormBridge is a headless form backend that receives submissions from any framework — plain HTML, React, Vue, Astro, or otherwise — and handles everything downstream: email notifications, storage, spam filtering, routing, and webhook integration. Point your form's action attribute at a FormBridge endpoint and submissions flow straight into a unified inbox, with no server code to write or maintain.

Key features

  • Unified inbox with search, filtering, starring, and status tracking
  • Email notifications with customizable routing based on form field values
  • Autoresponders with personalized templates and file attachments (up to 100 MB)
  • File upload support for submissions (100 MB per file)
  • Spam protection with built-in scoring plus optional reCAPTCHA v3 / hCaptcha
  • Webhook delivery to third-party services with auto-retry
  • Slack and Discord integrations
  • Custom SMTP per form for branded sender addresses
  • CSV export and a visual email template designer
