📚 Docs: https://formengine.io/documentation - In this step-by-step tutorial, I'll walk you through building a simple React demo app using FormEngine. You'll see how quickly you can design, render, and manage forms — without writing endless custom code.
The release of FormEngine 4.0.0 took place on May 15, 2025. If you're building complex forms in React, here's great news: Optimajet has released the core libraries of their FormEngine under the permissive MIT license, making it free to use — even in commercial projects.
Now following packages are distributed under the MIT license:
📦 NPM: react-form-builder/core
📦 NPM: react-form-builder/components-rsuite
📦 NPM: react-form-builder/viewer-bundle
All essential features of the React Form Builder are now completely free.
