Our verdict on PyDoctor

PyDoctor is a standalone, open-source command-line API documentation generator for Python projects. It analyzes Python modules and packages, resolves imports and inheritance hierarchies, and produces static HTML documentation. Developers documenting Python libraries and applications can use it to create API references from Python modules, Python packages, or C modules, with support for Windows, macOS, and Linux.

Its strongest area is the depth of its Python API analysis. PyDoctor computes inheritance hierarchies, parses Epytext, reStructuredText, Google, NumPy, and plaintext docstrings, and can add source-code links to generated pages. Configurable themes and templates, privacy settings, summaries, member ordering, and output paths provide control over how the documentation is presented. Intersphinx inventory generation and external API linking extend references beyond the project itself, while search and cross-references support navigation across the generated documentation.

PyDoctor also fits documentation workflows that publish from continuous integration. Published integrations include GitHub Actions, Read the Docs, Sphinx, and Intersphinx, with documented workflows for GitHub Actions and Read the Docs. Its output is centered on static HTML and Intersphinx inventory rather than a hosted documentation workspace, so teams should expect a command-line publishing model. PyDoctor is a strong fit for Python teams that want linked API references, source links, and configurable static output. Teams seeking a hosted service or broader language coverage should choose an alternative designed around those requirements.

How long have you used it?

I've used PyDoctor myself and this is my honest opinion — nobody paid or asked me to write it.
