rumdl is a fast Markdown linter and formatter written in Rust, inspired by ruff's approach to Python linting. It provides 82 lint rules, automatic fixing, TOML-based configuration, and support for multiple Markdown flavors like GFM, MkDocs, MDX, Quarto, and MyST.

Use cases

• lint markdown files in my repo
• auto-fix markdown style violations
• format markdown documentation consistently
• enforce markdown best practices in CI
• lint MkDocs or MDX flavored markdown
• replace markdownlint with a faster tool

When to choose

• you need very fast Markdown linting and formatting in Rust
• you want a single zero-dependency binary installable via cargo, pip, or standalone binaries
• you use Markdown flavors like GFM, MkDocs, MDX, Quarto, or MyST
• you want CI/CD integration with non-zero exit codes on violations

When to avoid

• you need linting for languages other than Markdown
• you require a plugin ecosystem or rules not covered by rumdl's 82 rules
• you depend on markdownlint-specific configuration files without migration support
