OpnForm is an open source form builder, offered as a managed cloud service and as self-hosted software. The self-hosted version runs as Docker containers that include an API worker for queued jobs and an API scheduler for periodic tasks. Forms and submissions can be managed through a REST API, and a JavaScript SDK controls forms embedded in a site.
Worth knowing
The core is licensed AGPL-3.0 or later, and the code under the api/app/Enterprise directory carries a separate proprietary license. The self-hosted license page says OIDC single sign-on works in the free install within a two-user limit across the instance, while SAML and LDAP need the Enterprise license.
