What JSON Forms is

JSON Forms is a free, MIT-licensed framework for creating form-based web interfaces inside applications. It lets developers build screens for entering, changing, and viewing data by defining the data with a JSON Schema and the presentation with a UI Schema. Data binding, input validation, and rule-based visibility are built in. Bindings are available for React, Angular, and Vue, with renderer choices including React Material and vanilla, Angular Material, and Vue vanilla and Vuetify sets. Developers can add or replace renderers, or use the core package to create bindings for another application framework. Validation uses AJV and can be customized by passing a custom AJV instance to the standalone component. The listed release is version 3.8.0, which adds support for Angular 22. Vue integration is marked as preview, as is the Vuetify renderer set, which also has known bugs. Community questions go to the forum, while code issues are directed to the repository issue tracker. Professional support includes guaranteed response times, detailed answers, code examples, advanced topics, a private channel under NDA, and feature prioritization.
