Sourcery vs Ruff: Python Code Quality Comparison

Quick Verdict Sourcery and Ruff solve fundamentally different problems in the Python code quality stack, which makes comparing them somewhat like comparing a mechanic to a speed gauge - both useful, not interchangeable. Ruff is an ultra-fast Python linter and formatter written in Rust that replaces Flake8, isort, Black, and over 50 Flake8 plugins in a single binary. It runs in milliseconds, catches style violations and common bugs through deterministic rules, and costs absolutely nothing. Source
