## What it is
MegaLinter is an open-source code quality tool that runs over 50 linters and formatters covering 50 languages, 22 formats, and 21 tooling formats in a single pass, detecting security issues, spelling mistakes, and copy-pasted code. It can be run via GitHub Action, other CI systems (GitLab CI, Jenkins, Azure Pipelines), or locally, with autofix and SARIF report support.

## Use cases
- lint all languages in my repository with one CI step
- automatically fix code style issues across a monorepo
- scan my repo for security issues and spelling mistakes in CI
- generate SARIF reports for code quality in GitHub
- run linters locally before pushing
- enforce code quality best practices across python java and golang projects
- lint terraform and markdown files in a pipeline

## When to choose
- you want a single tool to aggregate many linters across polyglot repositories
- you need CI integration with GitHub Actions, GitLab CI, Jenkins, or Azure Pipelines
- you want automatic fixes and SARIF security reporting out of the box

## When to avoid
- you only need one language-specific linter with fine-grained configuration
- you cannot use Docker or Node.js in your environment
- you require a permissive license (it is AGPL-3.0)

## Facets
- artifact type: cli-tool
