In their own words
JSON Schema for Humans
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`.
Scalar
Scalar is a set of API products for documentation, SDK generation, API registries, API requests, and MCP server use. Scalar Docs combines product guides and interactive API references generated from OpenAPI documents in a developer portal. Teams can write in Markdown or MDX, use GitHub content, preview pull requests, and publish through a CLI or after a merge. The SDK Generator builds idiomatic, type-safe client libraries from OpenAPI documents and can publish them through repository pull requests. Registry stores and versions OpenAPI and AsyncAPI documents, JSON Schema, and Spectral rules with Git integration. The open-source API Client works offline for sending requests, organizing collections, and testing APIs from OpenAPI documents. Scalar supports hosted and self-hosted deployment. Its Free plan is free and includes up to three APIs, one SDK with up to 25 endpoints, one editor seat, and 50 Agent Scalar credits. Pro is $150 a month; Business is $600 a month. Scalar states that it has received a SOC 2 Type 1 report and maintains GDPR-compliant privacy practices.
