## What it is
coala is a unified command-line interface for linting and automatically fixing code across many programming languages, driven by a single configuration file. It supports languages like Python, C/C++, Java, JavaScript, and CSS out of the box and integrates with editors and CI pipelines.

## Use cases
- lint code in multiple languages with one tool
- automatically fix code style violations
- enforce code quality in CI pipelines
- get linting results as JSON
- unify linting configuration across a polyglot codebase

## When to choose
- you work in a polyglot repository and want one linting config
- you want linting plus auto-fixing from a single CLI
- you need JSON lint output for custom tooling

## When to avoid
- you only lint one language and prefer its native, actively maintained linter
- you need a tool with frequent updates and a large active ecosystem
- you want editor-first linting rather than CLI-driven workflows

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: linter, cli, developer-tools, code-review
- domain: developer-tools, programming-languages, testing
- platform: windows, python, cli
- tags: linting, code-analysis, static-analysis, code-fixing, multi-language, ci-integration, command-line, linux, macos
