Qlty CLI is a multi-language code linter, auto-formatter, and security scanner.
Engineering teams use Qlty CLI for static analysis and auto-formatting of all of their code using a single tool with fast, consistent results.
As a Git-aware tool, Qlty CLI makes adopting linting into the development workflow easy by limiting results to only new issues.
Qlty CLI is implemented in Rust, supported by Qlty Software, free to use, and is published under a Fair Source license.
