PyMarkdown – Markdown linter

PyMarkdown is a Python Markdown linter built around its own parser. Its rules therefore work with the structure of a document rather than relying solely on individual lines of text.

The parser targets CommonMark and GitHub Flavored Markdown, giving lint rules detailed information about headings, lists, links and other document elements. Its rule engine separates checks into small, focused plugins so diagnostics remain specific.

PyMarkdown offers scan and fix modes and can also be integrated through pre-commit hooks or its API.

This is free and open source software.

Key Features

  • Uses a structure-aware Markdown parser targeting CommonMark and GitHub Flavored Markdown.
  • Implements checks as focused rule plugins running through a central rule engine.
  • Provides scan and automatic fix modes.
  • Supports pre-commit hooks for checking Markdown before changes are committed.
  • Exposes an API for integrating Markdown checks into other software.
