docfx is a static site generator for .NET API documentation that builds technical documentation sites with landing pages, markdown content, and API reference documentation for .NET and REST APIs.
The tool addresses the challenge of maintaining comprehensive technical documentation by extracting API information directly from .NET assemblies and combining it with custom markdown content into a unified documentation site. It processes source code metadata to generate reference documentation automatically, reducing the manual effort required to keep API docs synchronized with code changes. Users can organize content through markdown files and customize the site's appearance and structure through templates.
Teams building documentation for .NET libraries and services should consider docfx if they want integrated API reference generation tied to their codebase. The tool suits projects where developers need both auto-generated API documentation and hand-authored guides in a single site. It works well for organizations already invested in the .NET ecosystem and comfortable with command-line tooling for site generation.
The project transitioned to community stewardship and operates without a fixed release schedule, with new versions arriving when maintainers accumulate sufficient changes to warrant a release. Development uses the main branch for most work, with occasional feature branches for larger efforts, and the team encourages conventional commits in pull requests. The project maintains a public roadmap through GitHub Milestones, distinguishing between actively worked features in the Working Set and future candidates in the Backlog. Nightly builds are published to GitHub Packages, allowing early access to unreleased changes. The team actively solicits community contributions and marks beginner-friendly issues with help-wanted labels.
