About form.io

Form.io is an open source platform that combines a form builder with a data management API. You can create complex forms using a visual drag-and-drop interface, then embed them into any application. The platform handles form rendering, submission storage, and data validation out of the box.

It supports Angular, React, and Vue.js through native SDKs, plus a JavaScript renderer for other frameworks. The server component stores submissions in MongoDB and exposes a REST API for CRUD operations. Form.io also includes role-based access control, PDF generation, and webhook integrations for connecting to external services.

The core engine is free and open source under the MIT license, with a hosted cloud version available for teams that want managed infrastructure. It is maintained by the company Form.io, Inc. and has been used by enterprises like NASA and the Department of Defense for internal data collection tools.
