## What it is
Qlty CLI is a multi-language code quality tool written in Rust that unifies linting, auto-formatting, maintainability analysis, and security scanning across 70+ static analysis tools for 40+ languages. It is configured via a simple .qlty/qlty.toml file and is free for all use, with a companion cloud platform for automated code review and code coverage.

## Use cases
- lint and auto-format a polyglot repository with one tool
- run security scanning including SAST, SCA, and secret detection locally
- detect code smells like duplication and complexity
- enforce consistent code style across a team
- measure code quality metrics like complexity and LOC
- set up automated code review on pull requests
- track total and diff code coverage

## When to choose
- your team works across many languages and wants a single unified quality tool
- you want fast local linting and formatting with simple TOML configuration
- you want to consolidate multiple static analysis, SAST, and coverage tools into one
- you want to focus review on newly introduced issues via baseline analysis

## When to avoid
- you need Windows support today, as it is still in development
- you rely on a niche linter not among the 70+ supported plugins
- you need deep customization of a single analyzer beyond what Qlty exposes
- you prefer language-native tooling ecosystems over a wrapper CLI
