Metalsmith vs Nanoc

Metalsmith is a free, pluggable static-site generator for NodeJS that works more like a library than a framework. It transforms a directory tree into plain JavaScript objects that plugins can manipulate, without requiring a predefined project structure. Developers can use configuration over code or code over configuration, and access the package through either its JavaScript API or command-line interface. It works with npm, Markdown, JSON, YAML, and a templating language of choice. Example uses include static sites, scaffolding, backups, command-line and deployment tools, and eBooks made from Markdown for PDF, ePUB, or MOBI output. Starter repositories cover blog, company, resume, and clean-blog projects. Builds create static folders for deployment to CDNs, Netlify, GitHub Pages, GitLab Pages, SFTP hosts, or custom servers. Metalsmith requires NodeJS; the listed platforms include Linux, macOS, and Windows. The documentation says partial rebuilds are not available and suggests using a file watcher and browser synchronization package for automatic rebuilds. No billing terms or prices are stated on the supplied pages.

Nanoc is a free static-site generator that turns content such as Markdown or AsciiDoc into HTML. It is a command-line application for local site development and generating finished sites for deployment, not a CMS; content is usually managed on the filesystem. Its scope ranges from personal blogs to corporate websites. Free-form metadata lets pages take different roles, and markup options include Markdown, AsciiDoc and Textile, with eRuby, Haml and Mustache among its template languages. Users can write custom filters and helpers or bring in data from databases and web APIs. Nanoc supports incremental builds, multilingual sites and a local preview server. Deployment integrations include Git, rsync, GitHub Pages, Bitbucket, GitLab Pages and Netlify, and the tool can run checks before deployment. Ruby 3.1 or later is required, with CRuby needed for guaranteed support. macOS and Linux are officially supported; Windows has limitations and is not officially supported. Nanoc is MIT-licensed.
