Qlty

Qlty CLI

The free Qlty CLI is a polyglot, Rust-based command-line tool for universal linting, auto-formatting, security scanning, code smells, duplication, and maintainability metrics. It runs 70+ static analysis tools across 40+ languages natively (no Docker), is configured via a .qlty/qlty.toml file, and is free for all use including commercial projects. The CLI is a local developer tool, not an HTTP API; key commands include qlty init, qlty check, qlty fmt, qlty smells, qlty metrics, and qlty coverage publish.

OpenAPI Specification

openapi: 3.0.1
info:
  title: Qlty API
  description: >-
    Qlty is a code quality and coverage platform consisting of the free,
    open (Fair Source) Qlty CLI and the hosted Qlty Cloud service. As of this
    catalog entry, Qlty does not publish a documented public REST/HTTP API.


    Code quality analysis (linting, formatting, security scanning, code smells,
    duplication, and maintainability metrics) is performed by the Rust-based
    Qlty CLI, which is a local command-line tool rather than an HTTP service.
    Configuration lives in a .qlty/qlty.toml file in the Git repository.


    Code coverage is uploaded to Qlty Cloud with the CLI command
    `qlty coverage publish <report-file>`, authenticated by a per-project
    `QLTY_COVERAGE_TOKEN` environment variable. Supported report formats include
    lcov, Cobertura, Clover, JaCoCo, SimpleCov, dotCover, and xccov-json. The
    upload destination is handled internally by the CLI / GitHub Action and is
    not exposed as a documented public REST endpoint.


    Qlty Cloud itself (automated pull request review, quality gates, trends, and
    dashboards) is consumed through Git provider integrations (GitHub App /
    Action) and the web application, not through a documented public HTTP API.


    Because no public HTTP endpoints are documented, the paths object below is
    intentionally empty. This document will be updated if and when Qlty publishes
    a public API reference. No endpoints are fabricated here.
