## What it is
Mistune is a fast, dependency-free Python Markdown parser compatible with sane CommonMark rules, offering pluggable renderers, built-in plugins, and directives. It converts Markdown to HTML or AST and includes command-line tools.

## Use cases
- convert markdown to html in python
- parse markdown into an ast
- render markdown for a blog or documentation site
- extend markdown with custom plugins and directives
- convert markdown files from the command line

## When to choose
- you need one of the fastest Python Markdown parsers with no external dependencies
- you want pluggable renderers, AST output, or built-in plugins like footnotes, math, and TOC
- you need a mature, actively maintained library with a stable v3 API

## When to avoid
- you need strict full CommonMark compliance with mdast-compatible output - the author's newer Wenmode project targets that
- you need streaming output or maximum raw parsing speed beyond Mistune's benchmarks
- you need a Markdown parser outside the Python ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, templating, cli
- domain: web-development, documentation, parsers, developer-tools
- platform: python, cli, cross-platform
- tags: markdown-parser, commonmark, html-renderer, plugins, no-dependencies
