Metalsmith vs Stapy

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.

Stapy is a free, open-source static site generator from Magentix for building sites with Python. It runs on Linux and Windows, needs Python 3.6 or newer, and works without additional packages. A local preview server lets you view generated pages while working. Stapy writes static files into environment directories under the web directory, including a production directory intended for publishing. Page data is kept in JSON files, and page settings can be combined with layouts at several levels. Templates provide variables, included content, plugin methods and reusable child blocks. Themes can inherit from parent themes, with individual files overriding inherited files. Python plugins can alter content and page data during rendering, handle HTTP requests or add template methods. An official plugin adds a web editor at /_editor by default. Publishing documentation covers SFTP, Netlify, Cloudflare Pages, Vercel and GitHub Pages. The free plan costs nothing.
