OpnForm Product Information

What is OpnForm?

OpnForm is an open-source form builder for surveys, registrations, applications, intake processes, and internal workflows. It supports unlimited forms and submissions, logic and validation, calculations, prefilled fields, URL parameters, file uploads, webhooks, API access, and reusable templates.

Forms can be hosted by OpnForm or self-hosted, shared through a link, or embedded on a website. Higher tiers add branding control, domains, messaging integrations, access protection, analytics, AI generation, and workspace options; administrators must still configure retention, consent, access, and data-processing practices for the information collected.

Research basis: This is a source-based directory listing prepared from public product information; it is not represented as a hands-on test. Last updated August 8, 2026. Read our methodology.

How to use this tool

  1. Define the collection purpose and include only fields needed for that purpose, especially when personal or sensitive data is involved.
  2. Build the form with validation, conditional logic, calculations, prefilled values, and clear consent or privacy text where required.
  3. Configure confirmations, notifications, integrations, file permissions, retention, and access controls for the selected workspace.
  4. Submit representative responses on desktop and mobile, including invalid entries, large files, interrupted sessions, and conditional branches.
  5. Verify exports, webhooks, deletion requests, and administrator permissions before sharing the live link or embedding the form.
