Metalsmith vs Zola

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.

Zola is a static site generator that turns Markdown content into static HTML for blogs, knowledge bases and landing pages. It runs on Linux, macOS and Windows, and can also be self-hosted. Distributed as a single executable, it includes Sass compilation and syntax highlighting. Its maker says an average site generates in less than a second, including those steps. Because the output is static files, a published site does not need a database or server to manage. Zola uses CommonMark with added support for footnotes, GitHub-flavored tables, task lists and strikethrough. It uses the Tera template engine and can create multilingual sites with language-specific configuration and content. Users can define taxonomies and generate pages for their terms, such as categories, genres or tags. Search can run without servers or third parties, and indexing is configurable. Deployment guides cover Netlify, Vercel, GitHub Pages and Cloudflare Pages. The plan is free. Windows installation documentation says Zola does not work in PowerShell ISE. Code introduced after version 0.22 is licensed under EUPL-1.2; earlier code remains under MIT.
