What each one is

The product in its own terms, so the numbers below have context.

Ruff

Leader

A fast Python linter built in Rust that consolidates multiple linting tools into a single interface. It supports over 500 rules, provides automated fixes for common issues, and runs significantly faster than traditional Python linters on even very large codebases.

Independently observed

Trunk

A platform that identifies unstable tests, automatically isolates them from blocking merges, and provides intelligent merge queue management to reduce build delays and developer friction.
