RAML2HTML
RAML2HTML is a free, open-source Node.js package that generates HTML documentation from RAML.
What RAML2HTML is
RAML2HTML is a free, open-source Node.js package that generates HTML documentation from RAML. It can run from the command line or be used as a library. The command line renders a RAML file with the default theme, another installed theme, or a custom Nunjucks template. The project also gives an example of rendering RAML to Markdown with a theme. As a library, it accepts a filename, URL, or parsed RAML object as its render source. Its configuration can provide custom processing, HTML post-processing, output writing, and Nunjucks setup functions. RAML 1.0 files are supported in version 4 and later; version 3.x supports RAML 0.8. The package does not parse RAML, and the project directs parsing-error reports to raml-js-parser-2. The README instructs users to install it globally with npm. RAML2HTML is self-hosted, supports Linux, and is available under the MIT license. Additional themes can be installed from NPM, and the project welcomes GitHub pull requests.

Who it suits
RAML2HTML suits developers who want to generate RAML documentation in HTML and customize rendering through themes or Nunjucks. It is a fit for Linux-based, self-hosted workflows that already provide parsed RAML where needed.
Verdict
RAML2HTML provides a free route from RAML input to customizable documentation output. Account for its parsing boundary and version-specific RAML compatibility when selecting it.
