lintro
A unified CLI tool for code formatting, linting, and quality assurance
Decision gist · record as of 2026-08-14
Yes. Lintro is actively maintained, has low install friction (pure Python, no compiled deps), carries a permissive MIT license, and solves a real problem—unifying disparate linting and formatting tools under one interface. It's in beta (Development Status 4) and relatively young (first release 2025-08-17), so expect occasional rough edges, but the design is sound and the dependency chain is solid. Install it if you manage code quality across multiple languages or want to simplify CI/CD tool orchestration.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later.
- External linting/formatting tools (ruff, prettier, mypy, etc.) must be installed separately or via `lintro install --profile recommended`.
- Low friction: pure Python wheel with no compiled dependencies.

What it is and what it does
Lintro is a unified CLI wrapper that runs multiple code quality tools—linters, formatters, type checkers, and security scanners—across Python, JavaScript, Go, Rust, YAML, and other languages, all from a single command. Instead of maintaining separate configurations and invocations for ruff, prettier, mypy, clippy, and a dozen other tools, you run `lintro check .` or `lintro format .` and get consistent, standardized output (grid, JSON, HTML, CSV, or Markdown) across all of them.
It respects your existing tool configurations (.prettierrc, pyproject.toml, .yamllint, etc.) without requiring migration, auto-fixes issues where tools support it, and includes optional AI-powered summaries and fix suggestions (with your own API key). The package is actively maintained, requires Python 3.11+, and depends on well-established libraries like click, pydantic, rich, and httpx. External tools are detected on PATH or can be auto-installed; a Docker image is also available for isolated environments.
Use it for
- Run all linters and formatters on a codebase in one command instead of invoking each tool separately.
- Enforce consistent code quality across multiple languages in a monorepo with a single configuration layer.
- Generate standardized, human-readable reports (grid, JSON, HTML) from all tools at once for CI/CD pipelines.
- Auto-fix formatting and linting issues across Python, JavaScript, Go, Rust, and other languages in one pass.
- Integrate pre-commit hooks or GitHub Actions workflows that check code quality without tool-specific boilerplate.

Install
lintro on PyPI
Before you install
Low friction: pure Python wheel with no compiled dependencies. Active maintenance (released 2026-08-14, first release 2025-08-17). Requires Python 3.11+. Eleven runtime dependencies are all well-established packages (click, pydantic, rich, httpx, etc.), none of which introduce significant friction.
Requires Python 3.11 or later. External linting/formatting tools (ruff, prettier, mypy, etc.) must be installed separately or via `lintro install --profile recommended`.
