Quarto
Scientific publishing SSG. Markdown + Pandoc + Jupyter / R / Observable. Posit's tool.
VISIT QUARTOKey takeaway: When the document has to run code and the results have to appear in the output, Quarto is the strongest option in this directory and nothing else is close. Choose it for papers, books, dashboards, and research blogs. Choose almost anything else for a marketing site.

Templating: Pandoc Markdown Jupyter RMarkdown
What it is
Quarto is Posit's scientific and technical publishing system. Markdown + Pandoc + executable code blocks (Python, R, Julia, Observable). Replaces RMarkdown, Bookdown, blogdown, and Fastpages.
Best for
- Scientific blogs and books
- Research documentation with executable code
- Reports that mix prose with computation
When not to pick it
Skip Quarto for marketing or general content sites. The science-publishing opinions get in the way.
My take
For research and scientific publishing, Quarto is the strongest option. For general content sites, look elsewhere.
Executable documents as the unit of content
A Quarto document is Markdown with code blocks that actually execute at render time, in Python, R, Julia, or Observable, with the results, figures, tables, printed output, embedded into the finished page. That single idea separates it from every other generator listed here: the prose and the analysis cannot drift apart, because the numbers in the text are produced by the code in the file. Jupyter notebooks work as input directly, so an existing analysis becomes a page without a rewrite. Cross-references, BibTeX citations, figure numbering, and callouts are built in rather than plugin territory, because Pandoc does the heavy lifting underneath. The price of that power is a render step that runs your code, which means slower builds and a CI environment that needs the full scientific toolchain installed rather than just Node.
One source, many output formats
Because Quarto sits on Pandoc, the same source renders to a website, a PDF via LaTeX, a Word document, reveal.js slides, an EPUB, or a book with chapters and a table of contents. For academics and analysts that is the real selling point: one document goes to the journal, the seminar, and the web without maintaining three versions that slowly diverge. The website output is a competent static site with search, a sidebar, and a light and dark theme, but it is not competing with Astro or Starlight on design flexibility, and theming beyond the Bootstrap-based options is real work. Quarto also replaced a stack of separate R publishing tools, so a fair amount of the documentation and community material still speaks to that audience even though the Python path is fully supported.
Frequently asked questions
Is Quarto free?
Yes. Quarto is open source under the MIT licence and free to use, including all output formats. It is developed by Posit, who sell commercial products around the R and Python ecosystem, but the publishing system itself has no paid tier and no hosted requirement. You install the command line tool and render locally or in CI like any other generator.
Quarto or Sphinx for technical documentation?
Sphinx when the job is API reference tied to source code, where autodoc and its cross-reference resolution are unmatched. Quarto when the job is narrative documents containing live analysis, and when you also need PDF, slides, or a book from the same source. They overlap less than they appear: one documents code, the other publishes computation.
Does Quarto work with Jupyter notebooks?
Yes, directly. A notebook file can be a Quarto source document, so an existing analysis becomes a published page without converting it first. You can also work the other way, writing plain Markdown with executable code blocks and letting Quarto run them through the Jupyter kernel at render time, which keeps the source diff-friendly in Git.
