Quarkdown

Quarkdown is a modern Markdown-based typesetting system designed for versatility. A single project can compile into a book, an academic paper, a knowledge base, a documentation website, or a slide deck.

It extends GitHub Flavored Markdown with a Turing-complete scripting system, which lets authors define, reuse, and customize their content. Documents compile to HTML, PDF, MD and TXT, fully offline, with a fast live preview, a community-driven package ecosystem, and a language server.

Funding helps sustain full-time development, maintenance, security fixes, documentation, and community support, keeping Quarkdown a free and open alternative to LaTeX and proprietary typesetting tools.
