Daux.io review
A free, open-source generator for publishing organized Markdown as HTML or Confluence docs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Daux.io turns Markdown files arranged in folders into navigable project documentation. It is aimed at solo developers and small teams that want to work in Markdown and publish generated docs, rather than authoring in a separate documentation interface. The generator can run locally or on a web server, and its published options include static HTML, a single-page HTML document, and uploading documentation to Atlassian Confluence. It is open source and has a free plan, making it a fit for teams that prefer a self-hosted or locally run workflow.
Its output options are the main distinction. Daux.io automatically generates navigation and page sorting from the folder organization, adds syntax highlighting, and supports multiple languages. Built-in themes and custom themes provide presentation choices, while math, diagrams, and flowcharts extend Markdown documentation beyond prose and code. Confluence uploads offer a path for teams whose documentation destination is already Atlassian Confluence; Google Analytics and Piwik Analytics are also listed as integrations. Installation is available through PHP Composer or Docker, so teams should be comfortable with that kind of setup rather than expecting a hosted authoring service.
The trade-off is a focused scope: source material is Markdown files, and the listed outputs are HTML, single-page HTML, and Confluence. Daux.io does not provide versioned docs or API reference support, and support is community-based. That makes it a sensible choice for small teams seeking a free generator for folder-based Markdown, especially when generated HTML or Confluence publishing fits their workflow. Teams needing versioned documentation, API-reference generation, or a broader publishing workflow should consider another tool.
