OpnForm
Build forms, surveys and workflows with unlimited responses on every plan, including free.
OpnForm is an open-source form builder for creating forms, surveys, and workflows. It supports multi-step and single-page layouts, conditional logic, computed fields, answer piping, and redirects on submit, with AI-assisted form generation available as an option. Forms can be shared by link, embedded, added to Notion, hosted on a custom domain, or turned into QR codes for offline collection.
Responses can be routed to email, Slack, Discord, Telegram, Google Sheets, Zapier, Stripe payments, or any endpoint via webhooks and a REST API. Additional capabilities include custom themes, password-protected forms, form expiration, captcha, analytics, editable submissions, and versioning. Security features include SSO and SAML/LDAP, audit logs, two-factor authentication, and end-to-end data encryption.
OpnForm is available as a free plan with unlimited forms and submissions, with paid editions adding features such as branding removal, custom domains, custom SMTP, advanced integrations, roles and permissions, and priority support. It can be used on OpnForm's cloud, EU hosting, or self-hosted on-premise, with a free Community Edition and a paid Enterprise license for self-hosted deployments.
