Introduction

Formtress is a form submission platform that provides advanced spam and bot protection without CAPTCHAs or design compromises.

Instead of forcing users through reCAPTCHA, hCaptcha, or other disruptive challenges, Formtress uses algorithm-based validation to silently filter spam and bots on the server side. You get clean submissions — your users get a seamless experience.

You connect your HTML forms to Formtress via a lightweight script or npm package. Submissions are validated against your rules and forwarded to your integrations — email, webhooks, or (soon) HubSpot.

  1. Add a form in the dashboard — you get a unique Form ID.
  2. Drop in the script (or import the npm package) and tag your form with the ID.
  3. Automatic protection — algorithm-based spam and bot filtering runs on every submission.
  4. Set validation rules — add custom field-level rules to block unwanted submissions.
  5. Connect integrations — email notifications, webhooks to Zapier/Make, and more.
  6. Manage submissions — view, filter, review flagged spam, re-trigger integrations.
  • Freelancers & agencies building client sites in Webflow, static HTML, or any framework.
  • Developers who want form handling and spam protection without spinning up a server.
  • Teams that need shared workspaces, role-based access, and client billing.
