yamllint is a Python-based linter for YAML files that checks syntax validity plus style issues like key duplication, line length, trailing spaces, and indentation. It runs as a CLI, supports custom rule configurations, inline disables, and parsable output for editor integration.

Use cases

• lint yaml files for syntax errors
• check yaml indentation and formatting
• enforce yaml style rules in ci
• detect duplicate keys in yaml
• validate yaml config files before deployment
• integrate yaml linting into vim or emacs

When to choose

• you need configurable yaml style and syntax checking
• you want a lightweight CLI linter with parsable output for editors and CI
• you need per-line or per-file rule disables and ignore patterns

When to avoid

• you need linting for formats other than YAML
• you want a full YAML parser or data transformation library rather than a linter
