# Code Quality

> CLI Metalinter and VSCode extension for over 100 code checking tools.

<Info>
  Available as a CLI tool and VSCode extension, Code Quality is a separate from the Trunk Platform for CI Stability, which includes [Merge Queue](/merge-queue/merge-queue) and [Flaky Tests](/flaky-tests/overview). Code Quality runs entirely locally and does not require access to the Trunk web app or platform services.
</Info>

Trunk Code Quality is a **metalinter** that lets you lint every language and every file in your project with a single tool using 100+ supported idiomatic code-checking tools, such as ESLint, Prettier, Ruff, and more for every language and project.

Trunk Code Quality is trusted by popular open-source projects like [**ESLint**](https://eslint.org/) to improve their developer experience. [Learn more about how ESLint leverages Code Quality in their repos](https://trunk.io/blog/improving-linting-experience-in-eslint-s-open-source-repo-with-trunk-code-quality).
