About OpnForm
OpnForm is an open-source form builder that aims to be a simple, privacy-friendly alternative to Typeform and Google Forms. Its editor builds classic or step-by-step forms with conditional logic, hidden fields, file uploads, signatures, pre-filled links and custom CSS, and it integrates with Slack, Discord, Google Sheets, Zapier, webhooks and email notifications. The free cloud plan includes unlimited forms and submissions with no per-response fees, while paid plans add branding removal, custom domains, team features and enterprise controls such as SSO and audit logs. You can also self-host the core product for free with Docker and buy a self-hosted enterprise licence if you need more. The project's licence on GitHub is listed as a custom one, so check its terms if you plan commercial redistribution. It is a smaller project than the big vendors and has fewer templates and native integrations. It runs in the browser.
Best for: Privacy-minded teams that want free unlimited forms or a self-hosted builder.
