In their own words

gron

gron is a free, open-source command-line utility that turns JSON into separate assignments with visible paths. This representation helps users grep values in large or deeply nested JSON, including responses from poorly documented APIs. Input can come from a file, URL, or standard input. The --ungron option converts assignments back into JSON, while --json emits a JSON stream. Other options provide value-only output, colored or monochrome display, line-by-line streaming, insecure certificate handling, and sorting control. The output is valid JavaScript, and the project demonstrates comparing JSON files by diffing their gron output. If array entries are missing, ungron inserts null values to preserve keys. gron has no runtime dependencies. Installation instructions cover binary downloads, Homebrew, and Go install. It runs on Linux, macOS, and Windows; plan information also lists FreeBSD binaries. The repository uses the MIT license.

JSON Forms

JSON Forms is a free, MIT-licensed declarative framework for embedding form-based web interfaces in applications. Developers define data with a JSON Schema and describe presentation with a UI Schema. The framework supplies data binding, input validation, and rule-based visibility. Bindings are available for React, Angular, and Vue, with React Material and vanilla renderers, Angular Material renderers, and Vue vanilla and Vuetify sets. Developers can add or replace renderers or build bindings for another framework through the core package. 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, adding Angular 22 support. The project offers free community support through a public channel for basic topics, while professional support includes guaranteed response times, code examples, advanced topics, private NDA channels, and feature prioritization. Vue and Vuetify integrations are marked preview.
