JSON Schema for Humans vs phpDocumentor

JSON Schema for Humans generates static HTML or Markdown documentation from valid JSON Schema files. Inputs can be JSON or YAML, supplied to its command-line interface as a file, directory, glob pattern, or comma-separated list; Python methods are also available. Multiple templates produce different outputs. The default JavaScript template provides expandable sections, tabs for conditional subschemas, and anchor links. The js_offline template bundles CSS and JavaScript for offline viewing. Markdown output can be published without an HTTP server and is rendered by GitHub when browsing code. A techdocs template is described as optimized for TechDocs and MkDocs Material. References can point within a schema, to local files, or to URLs, including circular references, and the project lists JSON Schema Draft-07 support. Safe mode escapes HTML tags in descriptions by default, while configuration can allow HTML. Property names and size, property dependencies, and media are listed as unsupported. The Apache-2.0 licensed package documents installation with `pip install json-schema-for-humans`.

phpDocumentor is a free, open-source, self-hosted tool for analyzing PHP source code and DocBlock comments to produce API documentation. It can generate UML diagrams, parse Markdown and reStructuredText, and insert API-documentation sections into reStructuredText material. The site says full-text search works offline and describes CI integration through a GitHub Action or Docker image. Installation options include Docker, Phive, and a PHAR file; standalone installation requires PHP 8.1.2 or newer plus mbstring, while PlantUML is optional. The official Docker image supplies dependencies locally. The project also offers Composer-installable components for parsing, rendering, type resolution, and PHP reflection. It runs on Linux and macOS. Its Docker Hub overview does not actively support direct Composer installation because dependency conflicts may occur. No paid plans are listed; the plan costs nothing.
