jless vs JSON Forms

jless is a free command-line viewer for reading and exploring JSON and YAML on macOS and Linux. It formats JSON with indentation and syntax highlighting, and lets users open or close objects and arrays using vim-inspired commands. Search supports both full-text and regular-expression queries. jless reads files or standard input, including newline-delimited JSON; it can detect YAML from a file extension or read it with the --yaml flag. YAML comments and anchors are not shown. Users can copy values, keys, and paths to the system clipboard, or print them in the terminal, including a jq-style path for the focused node. It does not provide jq querying. Data mode gives a streamlined view, while line mode shows formatted JSON. Installation choices include Homebrew, MacPorts, Linux package managers, Cargo, downloadable binaries, and building from source with Rust. The project is MIT-licensed and available as a standalone binary. Its maker suggests it for exploring external APIs or debugging request payloads.

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.
