pajv - Polyglottal JSON Schema Validator

pajv is a command-line JSON Schema validator that supports multiple data formats including CSON, Hjson, JSON5, TOML, and YAML, in addition to standard JSON. Version 1.2.0 is the latest stable release, built on top of Ajv (Another JSON Schema Validator) and any-json for format parsing. It provides a unified CLI interface for validating data files against JSON Schema, with features like referenced schemas, custom keywords, and error formatting. pajv is a fork of ajv-cli and extends its functionality to support polyglottal input formats. The project is actively maintained with regular updates.
