mdlint

Opinionated Markdown formatter and linter, written in Rust. Inspired by ruff (Python) and gofmt (Go), it enforces a single canonical style with zero configuration. Version 0.3.17, released as an npm package with bundled platform-specific binaries. Active development; key differentiators: blazing fast (Rust), requires Node.js >=20, respects .gitignore, no config needed for default formatting, ESM-only wrapper. Unlike markdownlint (JS), it is opinionated and not rule-configurable. Aims to eliminate style debates and produce consistent diffs, particularly useful for AI-generated Markdown.
