JSON Forms
Munich, Germany
What it is
JSON Forms is a free, MIT-licensed framework for building form-based web interfaces embedded in applications. It lets developers define data with a JSON Schema and describe the form’s presentation with a separate UI Schema. Built-in data binding, input validation and rule-based visibility support forms used to enter, modify and view data. Bindings are available for React, Angular and Vue, with renderer sets including React Material and vanilla, Angular Material, and Vue vanilla and Vuetify. Developers can add or replace renderers, or use the core package to build bindings for another application framework. Validation uses AJV and can be customized with a custom AJV instance. 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 is also noted to have known bugs. Free community support uses a public channel for basic topics with longer response times; professional support includes guaranteed response times and advanced assistance.
