Sphinx

Sphinx is the most popular documentation generator in the Python ecosystem, used by major projects like Django, NumPy, and the Python language itself to create professional technical documentation. Originally developed for Python documentation, it now powers thousands of open source and enterprise documentation sites.

What makes Sphinx exceptional is its combination of powerful markup capabilities with automatic code documentation. The reStructuredText format provides semantic richness while autodoc features extract documentation directly from Python code, ensuring docs stay synchronized.

Python developers and technical writers choose Sphinx because it produces publication-quality documentation from simple text files. With extensive themeing, cross-referencing, and multi-format output, it handles everything from simple project docs to complex technical manuals.

Key Features

• reStructuredText Markup - Semantic, extensible markup language with rich formatting and cross-referencing capabilities • Automatic API Documentation - Extract documentation from Python docstrings with type hints and inheritance • Intelligent Cross-Referencing - Automatic linking between documents, functions, classes, and external resources • Multi-Format Publishing - Generate HTML, PDF, EPUB, LaTeX, and man pages from single source • Extensive Extension Ecosystem - 100+ extensions for diagrams, bibliography, search, and specialized domains • Professional Theming - Beautiful themes including Read the Docs, Book, and custom theme development • Code Block Integration - Advanced syntax highlighting with line numbers, emphasizing, and testing • Mathematical Notation Support - Full LaTeX math rendering with MathJax for complex scientific documentation
