Form.io
Open-source form and API platform for building forms, storing their submissions in MongoDB and serving them over an API, with a paid self-hosted Enterprise Server.
Form.io is a form and API platform: forms are built in a drag-and-drop builder, and the server keeps its data in MongoDB and serves it through an API. The repository holds the server and the management application, which the README runs with Docker Compose or with Node.js and MongoDB. Forms are embedded in Angular.js and React applications through a formio element from the separate formio.js library. Form.io LLC maintains the project, offers a hosted platform, and offers a self-hosted Enterprise Server.
Worth knowing
The Enterprise Server is a separate paid image that runs with a license key, and the pricing page lists it with an Enterprise Form Builder Module for building forms inside one’s own application. The project is licensed under OSL-3.0, a copyleft license, and the README records a change to that license from BSD.
