In their own words
MkDocs
MkDocs is a static site generator for project documentation written in Markdown, with project settings held in a YAML file. It produces static HTML that can be published to GitHub Pages, Amazon S3, or another static-file host. Its development server provides a local preview and refreshes it when documentation changes; generated sites also include search that can link to matching sections. The command-line tools cover creating a project, serving a preview, building the site, checking dependencies, and deploying to GitHub Pages. MkDocs uses Python-Markdown and requires a recent Python version and pip. The built-in mkdocs and readthedocs themes are available alongside third-party and custom themes, while plugins, Markdown extensions, and configuration options allow further changes. The built-in mkdocs theme supports several locales, including English, German, Spanish, French, Japanese, and Chinese. MkDocs is free, available for Linux, macOS, Windows, and self-hosted use, and distributed under the BSD license. Third-party themes and plugins run their authors’ code without sandboxing.
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.
