Mado is a newly released markdown linter developed in Rust, claiming to be up to 60 times faster than existing linters like markdownlint. It supports CommonMark and GitHub Flavored Markdown and is compatible with multiple platforms.
A new markdown linter named Mado, developed in Rust, has been released, claiming to be up to 60 times faster than existing solutions such as markdownlint, and supporting CommonMark and GitHub Flavored Markdown (GFM).
Mado is a markdown linter compatible with CommonMark and GFM, designed to improve performance significantly. Benchmark tests conducted on a MacBook Pro (2021, M1 Max) indicate that Mado processes approximately 49-60 times faster than markdownlint-cli and other similar tools, depending on the dataset. It can be installed via multiple package managers, including Homebrew, Nix, and Scoop, with pre-built binaries available for download. Mado supports most markdownlint rules, with some marked as unstable or unsupported, and can be configured through local or global configuration files. It is also compatible with GitHub Actions for integration into automated workflows.
Why It Matters
This development matters because faster markdown linting can significantly improve developer productivity, especially in large documentation projects or continuous integration pipelines. By leveraging Rust’s performance capabilities, Mado could reduce linting times from minutes to seconds, enabling more efficient code reviews and documentation updates. Its compatibility with existing markdown rules and integration options makes it a relevant tool for developers seeking performance improvements.

Background
Existing markdown linters like markdownlint and markdownlint-cli are widely used but have performance limitations, especially with large datasets. The recent benchmarking, conducted on a MacBook Pro with an M1 Max chip, shows that Mado outperforms these tools considerably. The release follows ongoing efforts within the developer community to optimize tooling for markdown processing, driven by the increasing size of documentation repositories and the demand for faster CI/CD pipelines.
“Mado leverages Rust’s speed to provide a markdown linting experience that is up to 60 times faster than existing tools.”
— Aki Omik, developer of Mado
“On a MacBook Pro (2021, M1 Max), Mado processes approximately 49-60 times faster than markdownlint-cli, depending on the dataset.”
